The BGP split horizon rule is confusing me. It states that routes learned by a IBGP router are not propagated to other IBGP routers. I guess this only regards IGP learned routes and trying to avoid that an IBGP router learns a IGP route before other parts of the AS which are needed for this route do. Is this right? .....
Secondly, when a route reflector is configured and it receives an update from a client, this route is propagated to all clients (except the originating client), and, which confuses me, to all nonclients. This is like an IBGP router (in this case a cluster) propagating routes to other IBGP peers, isn't ? How come there is no need for a split horizon rule here, or rather, since I don't seem to understand it very well, why is the effect that causes us to have a split horizon rule in the first place not there?
