Configuring BGP
12-17
name is the BGP neighbor peer group name that is the route reflector client.
Example
The commands in the following example configure Routers New York and Boston as
route reflector clients (as shown in Figure 12-6):
MOT(config)#router bgp 100
MOT(config-bgp)#neighbor 1.1.1.1 remote-as 100
MOT(config-bgp)#neighbor 1.1.1.1 route-reflector-client
MOT(config-bgp)#neighbor 2.2.2.2 remote-as 100
MOT(config-bgp)#neighbor 2.2.2.2 route-reflector-client
Configuring a Cluster-ID
A route reflector and its clients form a cluster. Usually a cluster of clients has a single
route reflector. The cluster is identified by the router ID of the route reflector.
If the cluster has more than one route reflector, use the bgp cluster-id command in
Router BGP Configuration mode to configure the cluster ID:
MOT(config-bgp)#bgp cluster-id <num>
where:
num is the number of the cluster ID; valid entries are 0 – 4294967295.
Example
In the following example,
the local router is one of the route reflectors serving
the cluster. The example configures the local router with the cluster ID to
identify the cluster.
MOT(config)#router bgp 100
MOT(config-bgp)#neighbor 156.80.20.12 route-reflector-client
MOT(config-bgp)#bgp cluster-id 40000
