No.... The RR will still reflect the non-RR-Client's routes, but ONLY to the
RR Clients. The RR will not reflect those routes to other IBGP or EBGP peers.

So then the only difference is that a non-RR-client will not have it's routes
reflected by the RR while the RR-clients will reflect to all types?

Danny,
Your assumption about what a RR client is, is correct.
If the RR did not reflect to IBGP Non-Clients, how would they know about the
routes coming from RR Clients? The only way would be to peer the RR Clients
with the IBGP Non-Clients, which would defeat the purpose of RRs. Therefore
the RR needs to reflect routes from RR clients to IBGP non-clients.
Hope this helps.

Subject: BGP question
I have a question about non-clients in a route-reflector topology. Assuming
all routers are in the same AS, you have a hub and spoke topology where the RR
has three peerings with three different routers. Only two of those neighbors
are configured as route-reflector-clients. In Doyle's routing TCPIP V. 2 pg.
127, it says that if a RR learns a route from a RR-client that route will be
sent to the other RR-client as well as the non-client. I am under the
impression that a non-client is simply a neighbor that is not configured as a
RR-client in the RR. If this non-client was in a different AS, I can see this
happening because that is EBGP, but IBGP assumes a full mesh, so how could the
RR send this route to the non-client? Of course, I'm going on the assumption
that a non-client is what I described previously. So I guess my question
really is, what is a non-client?
TIA,
Danny
