match command is configured, a match must occur in order for the continue statement to be executed. clause, the route map will execute the continue clause if a successful match Adds the IP address or peer group name of the neighbor in the specified autonomous system to the IPv4 multiprotocol BGP neighbor table of the local router. If the route map contains only set clauses, the set clauses will be executed automatically, and the route map will not evaluate any other route map entries. Continue clauses allow you to configure and organize more modular policy definitions so that specific policy configurations need not be repeated within the same route map. set commands that configure an additive or accumulative value (for example, If no successful matches occur, the continue clause is ignored. community Cisco recently announced availability of the latest release on the IOS-XE train – IOS-XE Gibraltar 17.4.1. deny} [sequence-number], 8. The BGP Route-Map Continue feature introduces the continue clause to BGP route-map configuration. This sequence does not contain a match clause, so the set clause will be automatically executed and the If a set action occurs in the first route map and then the same set action occurs again, with a different value, in a subsequent route map entry, the last set action may override any previous set actions that were configured with the same An account on Cisco.com is not required.

Configuring Stateful Switchover; Configuring Nonstop Forwarding This behavior is called an “implied continue.”. The route map itself specifies the match criteria and the resulting action if all of the match clauses are met. Continue clauses allow the network operator to configure and organize more modular policy definitions so that specific policy configuration need not be repeated within the same route map. Configures a Route Map Continue. remote-as will “fall through” to the next sequence number if one exists. There are two behaviors that can occur when the same show Set clauses are executed only after a successful match occurs, unless the route map does not contain a match clause. match ip address clause is supported. A packet arriving on the specified interface is subject to policy-based routing. Configures a Bug Search Tool and the release notes for your platform and software release. Continue clauses allow the network operator to configure and organize more modular policy definitions so that specific policy configuration need not be repeated within the same route map.

If there are no successful matches, the route map will fall through to route map entry 30 and execute the set clause. match ip address clause is supported. but, route-map have. set commands can be configured. The following configuration is for a trigger running Cisco IOS XR Software. This issue happened 2 times then I had to reload Switch . match and set clauses. route map will be evaluated normally. For example, a route map in Cisco IOS Software is now represented by a route policy: my-v6. Before the continue clause was introduced, route-map configuration was linear and did not allow any control over the flow of a route map. Route maps have a linear behavior, not a nested behavior. peer-group-name} Route Map Continue, IPv6 Routing: Multiprotocol BGP Extensions for IPv6, IPv6 Routing: Multiprotocol BGP Link-Local Address Peering, IPv6 Multicast Address Family Support for Multiprotocol BGP, Configuring Multiprotocol BGP (MP-BGP) Support for CLNS, Connecting to a Service Provider Using External BGP, BGP Route-Map Continue Support for Outbound Policy, Removing Private AS Numbers from the AS Path in BGP, BGP Support for Next-Hop Address Tracking, BGP Restart Neighbor Session After Max-Prefix Limit Reached, BGP Support for Dual AS Configuration for Network AS Migrations, BGP VPLS Auto Discovery Support on Route Reflector, IPv6 NSF and Graceful Restart for MP-BGP IPv6 Address Family, BGP Multipath Load Sharing for Both eBGP and iBGP in an MPLS-VPN, Loadsharing IP Packets over More Than Six Parallel Paths, BGP Policy Accounting Output Interface Accounting, BGP Support for IP Prefix Import from Global Table into a VRF Table, BGP Support for IP Prefix Export from a VRF Table into the Global Table, Configuring BGP: RT Constrained Route Distribution, BGP Diverse Path Using a Diverse-Path Route Reflector, BGP 4 MIB Support for Per-Peer Received Routes, BGP Support for Nonstop Routing (NSR) with Stateful Switchover (SSO), BFD—BGP Multihop Client The Cisco Support and Documentation website provides online resources to download documentation, software, and tools. Route Map Operation with Continue Clauses In this example, a clause is created to set the specified community. {ip-address| Continue clauses can go only to a higher route map entry (a route map entry with a higher sequence number) and cannot go to a lower route map entry. continue clause entries. In this example, the same Once a route is matched in a route map permit entry with a continue command clause, it will not be processed by the implicit deny at the end of the route-map. map-name SWSFMI11#show route-map route-map 10, permit, sequence 10 Match clauses: Set clauses: Policy routing matches: 0 packets, 0 bytes route-map PBR_TdP, permit, sequence 10 ...

Enables higher privilege levels, such as privileged EXEC mode. Mario Jost. If a successful match does not occur, the route map “falls through” and evaluates the next sequence number of the route map until all configured route map entries have been evaluated or a successful match occurs. Unless noted otherwise, subsequent releases of that software release train also support that feature. Multiple [sequence-number], 12. A sequence number is not specified for the only when a successful match occurs. Route map entries are evaluated in order starting with the lowest sequence number and ending with the highest sequence number. Route maps have a linear behavior and not a nested behavior. Configuration. Configuring Routing Information Protocol; BFD for RIPv2 Support; IPv6: RIPng VRF-Aware Support; SAF In the following example, when routes match an as-path of 10, 20, or 30, the routes are permitted and the continue clause jumps over the explicit deny clause to process the match ip address prefix list. After a match occurs, the route map stops evaluating match clauses and starts executing the set clauses, in the order in which they were configured. access-list-name], 9. Use Cisco Feature Navigator to find information about platform support and Cisco software image support. prepend command is configured to add an autonomous system number to the as-path. bgp Because the Cisco IOS is not capable of automatically failing over VTI tunnels, we will use the route-map functionality to prefer the Primary VTI. Continue clauses in outbound route maps are supported in Cisco IOS XE Release 2.1 and later releases. Enters router configuration mode, and creates a BGP routing process. The continue clause can be configured to go to (jump to) a specific route map entry by specifying the sequence number, or if a sequence number is not specified, the continue clause will go to the next sequence number. community-number additional entries in a route map after an entry is executed with successful as-path When a continue clause is configured, the route map will continue to evaluate and execute match clauses in the specified route map entry after a successful match occurs. Route map entries are evaluated in order starting with the lowest sequence number and ending with the highest sequence number.

The following table provides release information about the feature or features described in this module. This behavior is called an “implied continue.” If a match clause exists, the continue clause is executed only if a match occurs. community Unless noted otherwise, subsequent releases of that software release train also support that feature. If a continue clause does not exist in the next route map entry, the If the route map contains only set clauses, the set clauses will be executed automatically, and the route map will not evaluate any other route map entries. Depending on how many successful match clauses occur, the as-path is prepended by one, two, or three autonomous system numbers. set If the number of community lists in a match community clause within a To access Cisco Feature Navigator, go to This table lists only the software release that introduced support for a given feature in a given software release train.

This section lists the open bugs for Cisco IOS Release 15.5(3)S2. asked Oct 29 at 13:48. 2. To enable policy-based routing on an interface, indicate which route map the device should use by using the ip policy route-map map-tag command in interface configuration mode. continue In the following example, when routes match an as-path of 10, 20, or 30, the routes are permitted and the continue clause jumps over the explicit deny clause to process the match ip address prefix list. If no sequence number is specified, the continue clause will go to the route map with the next sequence number. according to check, some route-map statement doens't contain 'prefix' which already removed. The BGP Route match commands are met. In the next article, we will be configuring Route Based VPN tunnels with a dynamic routing protocol under different VRF's. Content Library . Configures a route map to continue to evaluate and execute match statements after a successful match occurs. The following sample output shows how to verify the configuration of continue clauses using the A continue clause can be executed, without a successful match, if a route map entry does not contain a match clause. only when a successful match occurs. The following example shows continue clause configuration in a route map sequence. 2. votes. autonomous-system-number, 4. none}, 10. After the match occurs, the route map stops evaluating match clauses and starts executing set clauses, in the order in which they were configured. additive, and match command is not configured, set and continue clauses will be executed. The set clause value in sequence 20 overwrites the set clause value from sequence 10. Exits router configuration mode and enters global configuration mode.
