Layer 3 Routing Commands 1264
routes to other clients within the cluster. When client-to-client reflection is
disabled, a route reflector continues to reflect routes from non-clients to
clients and from clients to non-clients.
The same command is available in BGP Router Configuration mode for IPv4
routes.
Command History
Introduced in version 6.2.0.1 firmware.
Example
console(config-router-af)#bgp client-to-client reflection
bgp cluster-id
Use the bgp cluster-id command to specify the cluster ID of a route reflector.
To revert the cluster ID to its default, use the no form of this command.
Syntax
bgp cluster-id cluster-id
no bgp cluster-id
• cluster-id—A non-zero 32-bit identifier that uniquely identifies a cluster
of route reflectors and their clients. The cluster ID may be entered in
dotted notation like an IPv4 address or as an integer.
Default Configuration
A route reflector whose cluster ID has not been configured uses its BGP
router ID (configured with bgp router-id) as the cluster ID.
Command Mode
BGP Router Configuration mode
User Guidelines
A route reflector and its clients form a cluster. Since a cluster with a single
route reflector has a single point of failure, a cluster may be configured with

client, each route reflector in a cluster should be configured with the same
