Command:

neighbor route-reflector-client


Mode:

Router(config-router)# 

Router(config-router-af)#

 

Syntax:

neighbor ip-address route-reflector-client

no neighbor ip-address route-reflector-client

 

Syntax Description:

ip address

IP address of the BGP neighbor being identified as a client


Command Description:

To configure the router as a BGP route reflector and configure the specified neighbor as its client, use the neighbor route-reflector-client command in address family or router configuration mode. To indicate that the neighbor is not a client, use the no form of this command.

Usage Guidelines:

By default, all internal BGP (iBGP) speakers in an autonomous system must be fully meshed, and neighbors do not readvertise iBGP learned routes to neighbors, thus preventing a routing information loop. When all the clients are disabled, the local router is no longer a route reflector.

If you use route reflectors, all iBGP speakers need not be fully meshed. In the route reflector model, an Interior BGP peer is configured to be a route reflector responsible for passing iBGP learned routes to iBGP neighbors. This scheme eliminates the need for each router to talk to every other router.

 

Example:

In the following router configuration mode example, the local router is a route reflector. It passes learned iBGP routes to the neighbor at 198.92.70.24.

Router(config)#router bgp 5

Router(config-router)#neighbor 198.92.70.24 route-reflector-client

In the following address family configuration mode example, the local router is a route reflector. It passes learned iBGP routes to the neighbor at 198.92.70.24.

Router(config)#router bgp 5
Router(config-router)#address-family ipv4 unicast
Router(config-router-af)#neighbor 198.92.70.24 route-reflector-client
