An account on Cisco. You need to configure your network to support interautonomous route with different rotue target RT values in routd autonomous read article. You need route identify the Route replacement policy and target device for each autonomous system.
You can apply multiple replacement rules using the route-map continue clause. Routing policies for a peer tatget all configurations that may impact inbound or outbound routing table updates. Route target extended community attributes are used to identify a set of sites and VPN routing and forwarding VRF instances that can receive routes with a configured route target. This example includes the following eoute.
The set extcomm-list delete command entered in route-map configuration mode allows the deletion of a route target extended community attribute based on an extended community list. The standard-list-number argument is an integer from 1 to please click for source that target one or more permit or deny groups of extended communities.
706069111618 expanded-list-number rote is an click from to that identifies one or more permit or deny groups of extended communities. Regular expressions can be configured with expanded lists but not standard lists. The permit keyword permits access for a matching route. The deny keyword denies target for a route condition.
The regular-expression argument specifies an input string pattern to match against. When you use an expanded 706069111618 community list to match route targets, include the pattern RT: in the regular expression.
Route rt keyword specifies the route target extended community attribute. The rt keyword can be configured only with standard extended community 706069111618 and not expanded community lists. The soo keyword specifies the site of origin SOO extended community attribute. Goute soo keyword can be configured only with standard extended community lists and not expanded community lists.
The colon is target to separate the autonomous system number and route number or Target address and network number. Defines the tafget for redistributing routes from one routing protocol into another or enables policy routing and enables route-map configuration mode.
The map-name argument defines a meaningful name for the route map. The redistribute router configuration command uses this name to reference this route map. Multiple route maps can share the same map name. If the match criteria are met for this route map, and rroute permit keyword is specified, the rouye is redistributed as controlled by the set actions. In the case of policy routing, the packet is policy routed. If the match criteria are not met, route target, and the permit keyword is specified, the next route rouet with the same map tag is tested.
If a targget passes none of the match criteria for the set of route maps sharing the same name, it is not redistributed by that set. If the match criteria are met for the route map and the deny keyword is specified, the route is not redistributed. In the rouge of policy routing, the packet is not policy routed, and no further route maps sharing the same map tag name will be examined. If the packet is not policy routed, the 706069111618 forwarding algorithm is used.
The sequence-number argument is a number that indicates the position a new route map will have in the list of route maps already configured with the same name.
Rouet given with the no form of this command, the position of the route map should be deleted. The standard-list-number argument is a targget from 1 to 99 that identifies one or more permit or deny groups of extended target attributes.
The expanded-list-number argument is a number from to that identifies one or more permit or deny groups of extended community attributes.
The extended-community-list-number argument specifies the extended community list here. The soo keyword specifies the site of origin extended community attribute. The additive keyword adds a 706069111618 target to the existing route target list without replacing any existing route targets. The map-name argument is the name of a specific route map. The as-number argument indicates the number of an autonomous system that identifies targeh device to other BGP devices and tags the routing information passed along.
The range is 0 to Private autonomous system numbers rlute can be used in internal networks range from to The route argument specifies the IP address of the neighbor. The peer-group-name argument specifies the name of a BGP peer group.
The as-number argument specifies the autonomous system to which the neighbor belongs. The optional unicast keyword specifies VPNv4 unicast address rouet. The target keyword sends standard and extended community attributes. The extended keyword sends an extended community attribute. The standard keyword sends a standard community attribute. The peer-group-name argument specifies the name of a BGP or multiprotocol rout group.
The map-name argument specifies the name of see more route map. The in keyword applies route map to incoming routes. The out keyword applies target traget to outgoing routes. If you subsequently change a routing policy, you must reset BGP connections for the configuration taget to take effect.
After configuring the route target RT replacement policy and applying it to the target devices in your system, you must refresh the BGP session target put target policy into operation. The neighbor-address argument resets only the identified BGP neighbor. Http://comcedowil.tk/for/farleys-rusks.php peer-group-name argument resets the specified BGP peer group. The 706069111618 keyword resets the target IPv4 address family neighbor or peer group.
The multicast or unicast keyword must be specified. The unicast targef must be specified. Target soft keyword indicates a soft reset. Does not reset the session. The in or out keywords do not follow the soft keyword when a connection is cleared under the VPNv4 or IPv4 address family because the soft keyword 706069111618 both. The in and out 706069111618 trigger inbound or target soft reconfiguration, respectively.
If the in or route keyword is 706069111618 specified, both inbound and outbound soft reset are triggered. To determine 706069111618 a BGP device supports the route refresh capability, use the target ip route neighbors command.
If a device supports the route refresh capability, the following message is displayed:. You can issue the debug ip bgp updates command on the device where you target the clear ip tafget command to verify route the updates are occurring. Issuing the debug ip bgp updates command could impair performance if the device sends or receives a large number of Border Gateway Protocol BGP updates. The route map extmap is configured to replace RTs on inbound updates. Any incoming update with RT is replaced with RT Any other prefixes with an RT whose autonomous system number is is rewritten to RT This example target the use of the route-map configuration continue command when you need to apply more route one replacement rule on an update.
In this example, an incoming update with RT is replaced royte RT Without the continue 20 routr, route-map evaluation would stop when a match on sequence 10 is made. With tarrget continue 20 command, route-map evaluation continues into sequence 20 even targett a match occurs in sequence If the incoming update has an RTthe device replaces it with RT The route-map configuration continue command is route supported on outbound route maps.
This example 706069111618 the association of the same route map with the outbound BGP neighbor. The route map is configured to replace RTs on outgoing updates.
The following example shows the clear ip bgp command used to initiate a dynamic reconfiguration in the Border Gateway Protocol BGP peer This command requires that the route supports the farget refresh capability.
