Routing policy. This help contains the following topics: Introduction.

Routing policy Each routing policy serves different use cases and scenarios. Intermediate per-path states are eliminated thanks to source routing. There could be a wide range of routing policies. DLS recomputes load sharing whenever a switch boots up or an E_Port or FX_Port goes online or offline. The model is intended to be vendor neutral to allow operators to manage policy configuration consistently in environments with routers supplied by multiple vendors. permit—Specifies the permit match mode for a routing policy node. This memo introduces a new set of simple extensions to the Routing Policy Specification Language (RPSL), enabling the language to document routing policies for the IPv6 and multicast address families currently used in the Internet. This is similar to how enforcement worked on MFA so far. With carefully architected policies, you can optimize how segments of your network process data, as well as how Route 53 offers several routing policies, each tailored for specific scenarios. g. This policy is not recommend for production sites. MULTIVALUE . The relation between the if-match clauses of a node is logical AND. Routing policies work Routing Policies are the rules that allows you to control and modify the default behaviour of the dynamic routing protocols like RIP, OSPF, IS-IS etc. 26. . Users will automatically Policy-Based Routing (PBR) is a technique used to make routing decisions based on policies set by network administrators rather than solely relying on the destination IP address. Click Edit. ¶ A routing policy is a named ordered list of routing rules that is applied to a listener. Bases: Enum Attributes. RouterOS implements several components that can Internet-Draft SR Policy Architecture November 2020 2. Routing policy is the generic term for all the mechanisms under policy-options in JUNOS. An SR policy can contain one or more candidate paths where each candidate path is identified in PCEP via an PLSP-ID. You can specify the virtual routing and forwarding (VRF) instance that the next hop belongs to or the default VRF instance is used. Each routing policy has a sequence of rules (called entries or statements) and a default action. Basically I am coming from Juniper world and need to create a routing policy that permits static, directly connected routes etc. When I apply the configuration, restart the networking or use netplan apply, only one of these routing-policies works: When I use netplan apply: eno1: First time, only the first routing-policy works. IP-based routing gives you granular control to optimize performance or reduce network costs by uploading your data to Route 53 in the form of user-IP-to-endpoint mappings. Examine the BGP table on C2 to verify the local preference of The Policy Based Routing policy layer page displays the new rule, including the selected sources, destinations, route type, and country. over ibgp/ebgp. RPL streamlines the routing policy configuration, reduces system resources required to store and Each routing policy is a collection of conditional statements and execution statements. Routing Policy Priority. org into the numeric IP addresseslike 192. This help contains the following topics: Introduction. Here are the different routing policies available in Route 53: 1. RPL was designed to support large-scale routing configurations. The Routing table is a logical data structure used to store the IP addresses and relevant information regarding the nearest routers. If no action is specified, the action specified using the Default Action parameter occurs. Routing policies are sorted by priority. In Border Gateway Protocol (BGP), the destination of a route is also known as its network-layer reachability information (NLRI). See an example of routing packets from 10. A higher number means lower priority: rules are processed in order by increasing priority number. Configure PBR. The export policy will advertise routes that were Use case Routing policy; Objective: Expose existing backend services through an API with minimal added complexity. The IRR has been in use since 1995 based initially on the RIPE-181 policy language. An SR Policy is made of one or more candidate paths. In most cases, the import policy will accept routes into the routing table. RPL streamlines the routing policy configuration, reduces system resources required to store and BGP was not designed for joint policy routing as discussed above; Source routing only improves the level of flexibility at the sources, and multi-path routing allows multiple policies at a single AS (e. It’s the simplest type of routing policy and is often used for small websites or applications that don’t Routing policy statements can consist of one or several entries. The default value is the name of the hosted zone. Evaluate Target Health – Specify Yes. This cmdlet returns one or more Emergency Call Routing policies. Do not export NLRI received carrying this community outside the bounds of this autonomous system, or this confederation if the local autonomous system is a Voice routing policies are used in "hybrid" scenarios: when some of your users are homed on the on-premises version of Skype for Business Server and other users are homed on Skype for Business Online. If the action is to accept or reject the label, that action is taken and the evaluation of the label ends. If you add health checks to all the records in a group of weighted records, but you give nonzero weights to some records and zero weights to others, health checks work the same as when all records have nonzero weights with the following exceptions: Policy Routing is a process whereby a device puts packets through a route map before routing the packets. The routing policy 80, in other words, may assign network addresses to the different biological regions 100 within the body area network 22. They generate a choice set of routing policies for each origin–destination (OD) pair by The routing policy language (RPL) provides a single, straightforward language in which all routing policy needs can be expressed. All ports with FICON devices attached must have PBR enabled. All the if-match Simple routing policy: Use for a single resource that performs a given function for your domain, for example, an Amazon EC2 instance that serves content for the example. The action predicate may return success, in which case the Although routing policies and firewall filters share an architecture, their purposes, implementation, and configuration are different. Segment Routing Policy Architecture Abstract Segment Routing (SR) allows a node to steer a packet flow along any path. You can assign the next hop to a next-hop group to use equal-cost multi-path (ECMP) routing. , instructions) that represent a source-routed policy. The packets steered into an SR Policy Segment Routing Policy Architecture Abstract Segment Routing (SR) allows a node to steer a packet flow along any path. ; Click Reorder to move a rule up or down in the policy order. A node with a smaller number is matched first. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. The caller ID for normal outbound PSTN calls is the phone number assigned to the resource account specified in the policy instance. Latency-based routing policy does ensure that the user will have a good experience in terms of latency. If it matches, the specified entry action is taken, either accepted or rejected. noswitchport 5 For extra routes, (both import and export) you can add route descriptions and reorder them (as of Apstra version 5. A label is compared to the first entry in the policy statement. Name - This will be the display name of the rule once created. routing-policy community-set name string member (bgp-std-community-type | bgp-std-community-regexp-type | identityref | bgp-large-community-type | bgp-large-community-regexp-type) Tree: member: Options: no-export. Example: In fast networks like data centers, straight-through routing minimizes latency and overhead. These Routing Policy allows you to modify the routes that are advertised to or accepted from a neighbor while using any of the supported routing protocols. The goal of policy based routing is to make the network as agile as possible. Packet flows are steered into an SR Policy on a node where it is instantiated called a headend node. Routes that meet all match conditions are permitted or denied based on the Policy based routing (PBR) is a technique that forwards and routes data packets based on policies or filters. When the routing policy that contains the action is used in the BGP view, BGP IPv4 unicast address view, or BGP IPv6 unicast address view, the action does not take effect. Assigning your Skype for Business Online users a voice routing policy enables those users to receive and to place phone calls to the public switched telephone The Routing Policy System Working Group intends to provide standardization of protocols and recommended practices neccesary to support interoperability of the Internet Routing Registry (IRR). This browser is no longer supported. Each routing protocol has a default policy. This is usually applied using the import / export statements in each of the protocols. When a router receives a packet it Learn how to use different routing policies with Route 53 to forward requests to one or multiple resources, based on weight, latency, geolocation, or health checks. aws_servicediscovery. Request routing policies allow you to route ingress traffic requests based on whether they match certain conditions you define. Beeram Juniper Networks 22 November 2024 YANG Data Model for Segment Routing Policy draft-ietf-spring-sr-policy-yang-04 Abstract This routing-policy ¶ Description¶ A named ordered list of routing rules that is applied to a listener. Travelers are assumed to choose a routing policy at the origin, instead of a fixed path. Routing policy parameterization provides users with a powerful and flexible configuration approach for policies that are often reused across BGP peers of a common type (such as transit, peer, customer, and so on). You cannot specify the same priority for routing policies that take effect in the same region and direction. Complete the following steps: The routing policy database (RPDB) controls the order in which the kernel searches through the routing tables. RPL streamlines the routing policy configuration, reduces system resources required to store and process these configurations, and simplifies troubleshooting. The route map determines which packets are routed next to which device based on the IP address and port number in the packet. It is possible to form composite policy actions by listing them one after the other. If you define a health check for the service and the health check is healthy, Route 53 returns the applicable value for up to eight instances. Durrani Equinix S. You will learn about importing and exporting routing policies in Junos, match cr routing-policy community-set name string member (bgp-std-community-type | bgp-std-community-regexp-type | identityref | bgp-large-community-type | bgp-large-community-regexp-type) Tree: member: Options: no-export. Some examples are below: Set some metric to routes learned from a particular neighbor. Packet flows are steered into an SR Policy on a This task is called 'policy routing'. Set some attributes (like AS PATH or Community value) to advertised routes to neighbors. It works by allowing administrators to define rules that dictate the path data packets should take through the network, based on various criteria such as source address, application type, or user identity. This command associates a routing ACL with a specific user role on a managed device. The entries specify the matching criteria. Packet flows are steered into an SR Policy on a Get started with the openconfig-routing-policy model using PAN-OS openconfig plugin. com Amazon Route 53 is a highly available and scalable cloud Domain Name System (DNS)web service. It affects control plane, route updates, A call routing policy (also called a voice routing policy) is a container for PSTN usage records. The activities of the RPS Working Group shall include (1) defining a Routing Policy. With IP-based routing in Amazon Route 53, you can fine-tune your DNS routing by using your understanding of your network, applications, and clients to make the best DNS routing decisions for your end users. Node. SR Policy An SR Policy is a framework that enables instantiation of an ordered list of segments on a node for implementing a source routing policy with a specific intent for traffic steering from that node. Second time, only the second routing-policy works. The routing policy's Details page appears. Please refer to Section 7 for a list of these attributes. Raza, Ed. About PBR. It helps control network traffic by defining which routes data packets should follow. DE-CIX India offers the following types of support: Do-It-Yourself Bilateral Peering. Shunwan Huawei Technologies D. 2. This document specifies the Path Computation The composite routing policy is straightforward and easy to follow [40], the picker will not traverse every aisle [21], in fact, to decide the shortest way to each aisle individually, Port-based routing (PBR) is a per-switch policy, where a path (default or user-configured) is based solely on the ingress port and destination. Weighted Routing Policy Route 53 offers several routing policies, each tailored for specific scenarios. Associate with Health Check – Specify No. Each node has a match mode of permit or deny. The next step is to confirm the order of the rules. A single geoproximity routing policy cannot contain two or more locations that are geographically situated within the same metropolitan area. Verification. Routes are matched against match conditions specified in routing policies in descending order of policy priority. RoutingPolicy (value, names = None, *, module = None, qualname = None, type = None, start = 1, boundary = None) . Click Save changes. This policy can contain multiple values but it returns one resource. Configuring active-passive failover with weighted records. 0 Description. The default action specifies a main action and optionally one or more route property modification actions. Without routing policy parameterization, the user must create individual routing policies, prefix-lists, AS-Path lists, community lists, and so on for Each routing policy can optionally be configured with a default action, which is applied to routes that do not match any policy statement. Policy-based routing (PBR) uses user-defined policies to route packets. Use the oci lb routing-policy get command and required parameters to get the details of a load balancer's routing policy: oci lb routing-policy get --routing-policy-name routing_policy_name- List of policy definitions, keyed by unique name These policy definitions are expected to be referenced (by name) in policy in import-policy and/or export-policy statements. , . Voice routing policies are used in "hybrid" scenarios: when some of your users are homed on the on-premises version of Skype for Business Server and other users are homed on Skype for Business Online. For instance, you can specify 25 for one resource and 75 for another, meaning that 25% of requests will go to Policy routing tables: Linux comes with three by default: local (which cannot be modified or deleted), main, and default. Enter the same name for all of the records in the group of Hi, the vrf-export policy is processed while sending routing updates towards your core network (RR or remote PE router), i. With the increasing demand for small-granularity businesses, the equipment management burden and computing capacity limitations caused by the huge increase of small A routing policy can contain multiple nodes, which are in a logical OR relationship. Policy. Failover. The routing policy aims to keep route selection sane, and avoid sending traffic outside of a region where possible. A route matches the routing policy if it matches one node (except the node configured with the continue clause) in the routing policy. Apart from providing Public Peering ports, DE-CIX India also supports its members in optimizing routing and establishing peering relationships over those ports. Routing policies also allow you to control which end-policy Cisco IOS XR Routing Configuration Guide for the Cisco XR 12000 Series Router, Release 4. Activate Policy. With static routing, whoever configured the static controls the routing protocol. Context routing-policy policy name string Configuring SBC Routing Policies. When a new packet arrives for routing (assuming the routing cache is empty), the kernel begins at the highest priority rule in the RPDB--rule 0. . This will expose the configuration panel: Enabled - Ensure the toggle is flipped to ON to enable the rule. Behavior: Returns one or more values without doing any special routing. 0/8 network to the Internet through a firewall device. Assigning your Skype for Business Online users a voice routing policy enables those users to receive and to place phones calls to the public switched telephone network by Segment Routing (SR) allows a headend node to steer a packet flow along any path. The routing policy language (RPL) provides a single, straightforward language in which all routing policy needs can be expressed. Click ‘Add policy routing rule’ to create a new rule. The system matches routes against the match conditions of routing policies in descending order of priority. Thus, an SR Policy openconfig-policy-types openconfig-version: 3. Home; EN Location. Why does BGP use Policy-Based Routing? BGP uses Policy-Based Routing because it allows network administrators to control how traffic flows between different autonomous systems Syntax Get-Cs Teams Emergency Call Routing Policy [[-Identity] <string>] [<CommonParameters>] Get-Cs Teams Emergency Call Routing Policy [-Filter <string>] [<CommonParameters>] Description. The commands to associate an access list to a user role vary, depending upon the type of access list being associated to that role. In current Note: Routing policy entries are compared against incoming packets. Do-It-Yourself Bilateral Peering . Valid values: 1 to 100. Refer to this policy information when configuring your Direct Connect router. Policy-based routing controls the size and content of the routing tables, the routes that are advertised, and the best route to take to reach a destination. Each different biological region 100 may thus be addressable to send/receive communications to/from the communications network 40. Use Case: Ideal for routing traffic to a single In computer networking, policy-based routing (PBR) is a technique used to make routing decisions based on policies set by the network administrator. Here’s a breakdown of what you can expect: 1. Entries are compared in the numerical sequence of the Entry IDs, from lowest to highest. If that single web server is Routing policy configuration has a significant impact on network operations, and as such, other YANG data models that reference routing policies are also susceptible to vulnerabilities relating to the YANG data nodes specified above. This avoids input/output (I/O) failures while rebalancing port paths. With a global network and multiple peers, the burble. It is designed for developers and corporations to route the end users to Internet applications by translating human-readable names like www. 5 GB), 100 (VE/CE 4 GB), 200 (VE/CE 8 GB), 400 (16 GB), and 600 (32-64 GB) Routing Policy rules. Additionally, some AWS Regions and Local Zones, such as US West (Oregon) and Portland, US, are situated too close to one another to be used within the same geoproximity routing policy. All routing protocols use the Junos OS routing tables to store the routes that they learn and to determine which routes they should advertise in their protocol packets. Policy-based routing enables you to configure complex routing scenarios. PBR and Track. Somewhat unintuitively, routes added to the system without a routing table specified go to the main table, not the default table. The Routing Policies table lets you configure up to 600 (SE), 20 (VE/CE 2 GB), 70 (VE/CE 3. (If you choose the simple routing policy for an alias record, you can specify only one AWS resource or one record in the current hosted zone. Routing policies enable you to control (filter) which routes a routing protocol imports into the routing table and which routes a routing protocol exports from the routing table. ((). •Aftertheroute-policyhasbeenentered The Teams shared calling routing policy configures the caller ID for normal outbound PSTN and emergency calls made by users enabled for Shared Calling using this policy instance. You could define different routing policies based on protocol, source/destination IP and source/destination port, and you could set effective time to make policy routing take effect in the specific time period. You can find the list of first-factor modes that you can enforce in routing policy and MFA modes available respective to that. A Routing Policy determines the routing and manipulation (inbound and outbound) rules per SRD in a multiple SRD configuration topology. The last two options shift that rule up or down by one If you choose the simple routing policy in the Route 53 console, you can't create multiple records that have the same name and type, but you can specify multiple values in the same record, such as multiple IP addresses. That decides the path that’s taken to a given destination network or host. When matching traffic, we can use keywords like ‘exact’, ‘longer’, and ‘orlonger’ for advanced prefix matching. Each policy routing rule consists of a selector and an action predicate. You can configure one or more actions in a term. Typically this is the organization's main auto Default Description OneTrust LLC (OneTrust) is a provider of privacy management software platform. The Routing Policy Specification Language (RPSL) is a language commonly used by Internet Service Providers to describe their routing policies. Scribd is the world's largest social reading and publishing site. Policy routing considers aspects such as source/destination address, ports, protocol, type of service (ToS), and entry interfaces; do not confuse it with a routing policy or traffic policing. Packet flows are steered into a SR Policy on a node where it is instantiated called a headend node. This document describes a YANG data model [] for routing policy configuration based on operational usage and best practices in a variety of service provider networks. txt) or read book online for free. The packets steered into an SR Policy Click Next after you finish defining the rules. 0 OL-23246-02 3 Implementing Routing Policy on Cisco IOS XR Software Information About Implementing Routing Policy ƒ 8D ó P„ so6}¾{. The routing policies are stored at various whois databases including RIPE, RADB and APNIC. Routing Policy - Free ebook download as PDF File (. Routing policies in Apstra include the following details: Policy Routing Policies could be used to tell the router (self or neighbors) what routes and their attributes needs to be put into the routing table. The command sets a next hop IP address for the routes that match the relevant route-policy, which may change the service forwarding path. The Edit routing policy dialog box appears. You can also use weighted records for active-passive failover, with caveats. Choose Geolocation. " The backend set must be one you have already created. With this control and modify mechanims, you can arrange the routing facilities for your network needs. The header of a packet steered in an SR Policy is augmented with the ordered list of segments associated with that SR Policy. Segment-routing policy — a policy identified by the tuple of (head-end Internet-Draft Segment Routing Policies in BGP June 2021 situations, BGP Route Reflectors may be used to propagate the advertisements, or it may be necessary for the advertisement to propagate through a sequence of one or more AS. Q3. Failover Record Type – Specify Secondary. SPRING Working Group K. Routing traffic from a specific subnet to a Each term in a routing policy can include two statements, from and to, to define the conditions that a route must match for the policy to apply: Segment Routing (SR) allows a node to steer a packet flow along any path. A policy-based route can be configured under Network-wide > Routing > Policy routing. routing-policy-map . configureterminal 3. The kernel iterates over each rule A segment-routing policy intended for use by a particular head-end router can be statically configured on that router or advertised to it in the form of a BGP route. those BGP neighbors that are defined in the global routing instance with family inet-vpn unicast, while the standard export policy is evaluated for updates towards your CE router. Use this only when you have exactly one resource such as one EC2 web server. In a composite policy action, the actions are executed left to right. This policy is used for the life cycle of emergency call routing - emergency numbers Routing policy parameterization allows operators a powerful and flexible configuration approach to routing policies for policies are often reused across BGP peers of a common type (such as, transit, peer, customer). Example FortiGate will first check regular policy routes before coming to SD-WAN policy routes (if any) and then the routing table. These sites block access The routing policy language (RPL) provides the ability to test destinations for a match to a list of prefix match specifications using the in operator. Choose from among Move to top, Move to bottom, Move up, or Move down. interfacetypenumber 4. to balance the E_Port load across all E_Ports with the same The routing policy language (RPL) provides a single, straightforward language in which all routing policy needs can be expressed. To make this possible, an attribute needs to be attached to the advertisement that enables a BGP speaker to determine whether it is intended RFC-4012: Routing Policy Specification Language next generation (RPSLng) Recommended reading. Use Case: Ideal for routing traffic to a single Specify a priority for the routing policy rule, to influence the order in which routing rules are processed. The default action is applied to all routes evaluated by the policy that do not match any By default, the kernel in RHEL decides where to forward network packets based on the destination address using a routing table. When PBR is active, you can enable DLS to optimize routing by sharing traffic among multiple equivalent paths between switches. dn42 network typically has many alternative route paths for reaching a particular destination. Skip to main content Skip to in-page navigation. For example, you can route packets based on various criteria, such as the source address, packet metadata, or protocol. When a routing policy takes effect, it affects inter-AS VPN route receiving and advertising. All routing policies are listed in tabular form. You create and manage voice routing policies by going to Voice > Voice routing policies in the Microsoft Teams admin center or by using Windows PowerShell. Including the new multianswer routing policy. For example, generate some test traffic from the configured source IP / subnet and check on the traffic logs for the outgoing interface. The headend node steers a flow into an SR Policy. This is an example of what I have configured on my existing Juniper router: policy-statement iBGP-Direct {term iBGP-direct-permit {from protocol direct; then accept;}} and this policy statement is applied to my bgp config to RP/0/RP0/CPU0:router(config)# route-policy sample1 Entersroute-policyconfigurationmode. Check . E-Port Balance Priority. See Creating a Load Balancer Routing Policy for details on the routing policy settings. Voyer Bell Canada M. eno2. This is used to identify a network node for routing purposes. e. The rules are evaluated in the order you define and the evaluation stops at the first match. This starts like simple policy but with a health check. An SR policy is identified by <headend, color, end-point> tuple. IANA Considerations IANA has registered the following URI in the "ns" subregistry of the "IETF XML Registry" [RFC3688]: URI: The routing policy attributes whose values can be modified in policy actions are specified in the RPSL dictionary.

This module contains general data definitions for use in routing policy. Each term in a routing policy can include a then statement, which defines the actions to take if a route matches all the conditions in the from and to statements in the term: Internet-Draft SR Policy Architecture May 2021 2. Only the routes that meet the matching rules are accepted. In policy-based routing (PBR), an administrator establishes rules that match certain characteristics of the traffic in order to determine which paths it should take. It can even be used to steer local and overseas traffic to different gateways. Click the routing policy whose details you want to get. Learn about routing policy behaviors and managing routing policies. Traffic policing and shaping are sometimes summarized as traffic conditioning. Review the following examples of how to use Policy Based Routing (PBR) rules to address specific use cases. It greatly reduces the redundancy inherent in previous routing policy configuration methods. Policy within the dynamic protocols listed will filter or manipulate the way you use the information.

Matsushima SoftBank V. Latency-Based Routing: Region Failovers for Your Serverless A routing policy is a set of rules that dictates the path data takes through a network. When you create a record, you choose a routing policy, which determines how Amazon Route 53 responds to queries: Simple routing policy – Use for a single resource that performs a given function for your domain, for example, a web server that serves content for the example. for a specific SLA) from that node. Policy Objectives. , AS3), selecting different routes for each upstream neighbor (e. Route Server (Public Peering) IPv4 & IPv6 Peering. You can use the filter-policy command in the protocol view and apply an ACL or an IP prefix list to filter the received routes. Record name. The Segment Routing architecture [] specifies that any instruction can be bound to a segment. RPL streamlines the routing policy configuration, reduces system resources required 1. When the communications device 34 receives the biological signal 30, A routing policy can be realized as different paths depending on the realizations of travel times; a path is a special routing policy where the action is independent of time or information. Applying routing policy parameters to BGP neighbors doesn’t necessarily change the BGP table, as the new routing policy might be evaluated only on new incoming updates. There is an example of daily use below showing Policy Based Routing Policy Examples. The SR Linux supports policy-based routing. When Voice routing policies are used in "hybrid" scenarios: when some of your users are homed on the on-premises version of Skype for Business Server and other users are homed on Skype for Business Online. The filter-policy import command is used to filter received routes. You can use the global (Org-wide default) policy or create and assign custom policies. Saleh Intended status: Standards Track Cisco Systems Expires: 26 May 2025 Z. Segment Routing (SR) allows a node to steer a packet flow along any path. Note. com website. If no default action is specified, the default action for the routing-policy-map. geeksforgeeks. This approach ideally suits applications that require (DLS) to optimize the selected routing policy by balancing the load across the available output ports within a domain. If the keyword additive is not set in the apply extcommunity command, the original extended community attribute is Step 3: Routing Table. Table 1 describes their purposes. Every time, only the second routing Routing policies allow you to control the routing information between the routing protocols and the routing tables and between the routing tables and the forwarding table. SR Policy An SR Policy is a framework that enables the instantiation of an ordered list of segments on a node for implementing a source routing policy for the steering of traffic for a specific purpose (e. 9. This type pf routing is called Policy Based Routing. These rule conditions can use boolean and near-match operations. This document details the concepts of SR Policy You can implement policy within these protocols, but this is not policy-based routing (PBR). Download Microsoft Edge More This document introduces a mechanism to specify a Segment Routing (SR) policy, as a collection of SR candidate paths. 0. branch <XX:XX:XX:XX:XX:XX> access-list <STRING> role <STRING> access-list <STRING> Description. Click the routing policy you want to edit. A policy can specify parameters for packets that match specific criteria such as ACLs, packet lengths, service Segment Routing (SR) allows a node to steer a packet flow along any path. The destination in command is protocol-independent. If you're creating a record that has the same name as the hosted zone, don't enter a value (for example, an @ symbol) in the Name field. RPL streamlines the routing policy configuration, reduces system resources required Policy-based routing. Routing Policy for Balanced Management of Slices Using Flexible Ethernet Abstract: Flexible Ethernet (FlexE) technology meets the business needs of multi-granularity bandwidth, low latency, high reliability.
