Route reflection functionality can be configured as follows:
RS G8264(config)# router bgp
RS G8264(config­router­bgp)# as 22
RS G8264(config­router­bgp)# enable
RS G8264(config­router­bgp)# neighbor 2 remote­address 10.1.50.1
RS G8264(config­router­bgp)# neighbor 2 remote­as 22
RS G8264(config­router­bgp)# neighbor 2 route­reflector­client
RS G8264(config­router­bgp)# no neighbor 2 shutdown
Note: When a client is configured on the G8264, the switch automatically gets
configured as a route reflector.
RS G8264(config)# show ip bgp neighbor 2 information

Once configured as a route reflector, the switch, by default, passes routes between
clients. If required, you can disable this by using the following command:
RS G8264(config­router­bgp)# no client­to­client reflection
You can view the route reflector BGP attributes attached to a BGP route using the
following command:
