Parameters

cluster-id: Specifies the cluster ID in the format of an integer, in the range of 1 to 4294967295.

ip-address: Specifies the cluster ID in the format of an IPv4 address in dotted decimal notation.

Usage guidelines

The route reflector and clients form a cluster. Typically a cluster has one route reflector. The ID of the route

reflector is the cluster ID.

You can configure more than one route reflector in a cluster to improve network reliability and prevent a

single point of failure. Use this command to configure the same cluster ID for all route reflectors in the

cluster to avoid routing loops.

Do not configure the router ID of a client as the cluster ID.

Examples

# In BGP IPv4 unicast address family view, configure the cluster ID on the local router (a reflector in the

cluster) as 80.

[Sysname-bgp-ipv4] reflector cluster-id 80

# In BGP VPNv4 address family view, configure the cluster ID on the local router (a reflector in the cluster)

as 80.
