RE: BGP Problem

Hmm, I am a bit confused

 

In your original email "RTR_B & RTR_C is route-reflector for RTR_M & RTR_N"

In your last email "B & C is route-reflector client for M & N"

 

I think it only work if you configure M & N as RR for B & C. The "neighbor
x.x.x.x route-reflector-client" commands have to be configured on M & N. You
do not need this command on B &C.

 

Would you please post the config

 

Cheers,

 

Huan

EBGP between A & B only
 
B & C is route-reflector client for M & N
 
There is a IBGP between M & N
 
 
my problem is "C" is not learning routes, which B is learning from its E-BGP
peer.
