![]() ![]() 'Non-Clients' is the default setting for the peer, hence route reflector is disabled by default. Note: If both peers are configured as 'Non-Clients,' then no routes are advertised. A route learned from a non-client can be forwarded to another EBGP neighbor and client, but not to a non-client.A route learned from a client can be forwarded to another EBGP neighbor, client and non-client.This requires the IBGP peers to be configured as client/non-client on B2:Ĭonsider the following aspects of advertisement while configuring the peers as client/non-client : No configuration is required on the peers themselves ,but only the device, which will be acting as a route reflector. To enable B2 to advertise the routes learnt from IBGP peers to other IBGP peers, make it a route reflector.
