In a BGP autonomous system with several Route Reflector clusters into it, should all BGP clusters be fully Meshed?
I read design docs of hierarchical RR architectures, where a backbone RR cluster is the hub of several “spoke” regional RR clusters, so that every regional RR cluster maintains one or two peering sessions with members of the hub RR cluster, but not with other BGP peers in neighboring Regional RR clusters.
But there are some other docs which says that in a BGP AS, all the existing BGP clusters must establish a full mesh peering topology with at least one member of every cluster.
