Below is an excerpt from a Cisco case study on multiple route reflectors within a cluster:
An important thing to note, is that peer-groups were not used in the above configuration. If the clients inside a cluster do not have direct IBGP peers among one another and they exchange updates through the RR, peer-goups should not be used. If peer groups were to be configured, then a potential withdrawal to the source of a route on the RR would be sent to all clients inside the cluster and could cause problems. The router sub-command bgp client-to-client reflection is enabled by default on the RR. If BGP client-to-client reflection were turned off on the RR and redundant BGP peering was made between the clients, then using peer groups would be alright. Does anyone know what they mean? I know in IOS versions 12.0 and lower there were issues with route reflection using peer groups, but I am trying to figure out what they are trying to say here. What do they mean by a potential withdrawal to the source of a route on the RR? Any help would be appreciated. Guy H.
