BGP and BGP4+ Commands

neighbor route-reflector-client (BGP)

Use this command to configure the router as a BGP route reflector and configure the specified neighbor as its client.

Use the no variant of this command to indicate that the neighbor is not a client.

Syntax neighbor <neighborid> route-reflector-client

no neighbor <neighborid> route-reflector-client

Parameter Description

<neighborid> {<ip-address><peer-group>}

<ip-address>The address of an IPv4 BGP neighbor, in dotted decimal notation A.B.C.D.

<peer-group>Enter the name of an existing peer-group. For information on how to create peer groups, refer to the neighbor peer-group (add a neighbor) (BGP and BGP+) command on page 3.144, and neighbor route-map (BGP and BGP4+) command on page 3.159. When this parameter is used with this command, the command applies on all peers in the specified group.

Mode Router Configuration or IPv4 Address Family Configuration for a VRF instance

Usage Route reflectors are a solution for the explosion of iBGP peering within an autonomous system. By route reflection the number of iBGP peers within an AS is reduced. Use the neighbor route-reflector-clientcommand to configure the local router as the route reflector and specify neighbors as its client.

An AS can have more than one route reflector. One route reflector treats the other route reflector as another iBGP speaker.

In the following configuration, Router1 is the route reflector for clients 3.3.3.3 and 2.2.2.2; it also has a non-client peer 6.6.6.6:

Router1# router bgp 200

neighbor 3.3.3.3 remote-as 200 neighbor 3.3.3.3 route-reflector-client neighbor 2.2.2.2 remote-as 200 neighbor 2.2.2.2 route-reflector-client neighbor 6.6.6.6 remote-as 200

Examples

awplus# configure terminal

awplus(config)# router bgp 10

awplus(config-router)# neighbor 10.10.0.72 route-reflector-client
