That's for IBGP updates...
Ebgp updates are sent by an IBGP peer to all its ibgp peers all the time...
(or I would need MCI T-3 lines and BGP peering session on 20 routers,
instead of 2, LOL)

the rule of RR is
Client to non-Client
Client to Client
but non-Client to non-Client is not going to send updates.
R2 and R5 will be clients mean for example
R3
nei R2 remot 100
nei R2 route-reflector-client
nei R5 remot 100
nei R2 route-reflector-client
R4
nei R2 remot 100
nei R2 route-reflector-client
nei R5 remot 100
nei R2 route-reflector-client
R3 and R4 here are servers so they will send only to the clients and if
there will be an update from R2 to R4/3 it Will not be sent to R1 as both
R4/3 and R1 are non-Client.
I think I am going to Dynamips it just to see that what i am saying here is
true on reality but as far of the rules that is how it should act.
