Yes. All route-reflector servers within your network should be fully
meshed.

All route-reflector servers peer as non-clients.

Read BGP 101. A client router is just like any other BGP router, the
protocol allows for a BGP router to hear multiple announcements for the
same destination. The router will choose the best destination based on
the usual BGP decision rules.
