Oh, ok. So this router only knows about a single path.

Well, in this case, your route reflector seems to prefer the eBGP
learned prefix over the other one, this is why it is not sending the
alternate path to the router, and your router only shows one path. Can
you show "show ip bgp <prefix>" from the RR?
