Border Gateway Protocol IPv4 (BGPv4) | 355
Command Modes
ROUTER BGP
Usage
Information
A route reflector reflects routes to the neighbors assigned to the cluster. Neighbors in
the cluster do not need not be fully meshed. By default, when no route reflector is
used, internal BGP (IBGP) speakers in the network must be fully meshed.
The first time you enter this command the router is configured as a route reflector and
the specified BGP neighbors are configured as clients in the route-reflector cluster.
When you remove all clients of a route reflector using the
no neighbor
route-reflector-client command, the router no longer functions as a route reflector.
If the clients of a route reflector are fully meshed, you can configure the route
reflector to not reflect routes to specified clients by using the
no bgp client-to-client
reflection
command.
