To configure the cluster ID if the BGP cluster has more than one route reflector, use the bgp cluster-id router configuration com mand. To remove the cluster ID, use the no form of this command.
bgp cluster-id cluster-id
no bgp cluster-id cluster-id
cluster-id Cluster ID of this router acting as a route reflector; maximum of 4 bytes.
The router ID of the single route reflector in a cluster

Together, a route reflector and its clients form a cluster .
Usually a cluster of clients will have a single route reflector. In that case, the cluster is identified by the router ID of the route reflector. In order to increase redundancy and avoid a single point of failure, a cluster might have more than one route reflector. In this case, all route reflectors in the cluster must be configured with the 4-byte cluster ID so that a route reflector can recognize updates from route reflectors in the same cluster.
If the cluster has more than one route reflector, use this command to configure the cluster ID.
In the following example, the local router is one of the route reflectors serving the cluster. It is configured with the cluster ID to identify the cluster.
router bgp 5 neighbor 198.92.70.24 route-reflector-client bgp cluster-id 50000
| Command | Description |
|---|---|
| bgp client-to-client reflection | Restores route reflection from a BGP route reflector to clients. |
| neighbor route-reflector-client | Configures the router as a BGP route reflector and configure the specified neighbor as its client. |
| show ip bgp | Display entries in the BGP routing table. |
