Split horizon won't allow BGP to advertise the iBGP route back to the client
from which it was learned. If the router loses the route learned from that
peer though, it will re-advertise it.

Subject: [nsp] When would a reflector not send to another client?
I have 4 routers. One of them has BGP neighboring wth the 3 others, and has
"route-reflector-client" with 2 of them. For a certain route it has two
choices, one via a reflector (IBGP) and the other one through the
non-reflector,
which is EBGP.
When the EBGP route is chosen, the route is advertised to the reflector
peers.
When the route via the reflector is chosen (in case of a higher local-pref),
the route is not advertised.
Synchronization is off.
I read the IOS manual on this topic but nothing relevant is explained.
Thanks in advance!
