Vikas, The result was that C 'knew' via the BGP session with A, that to get to external network 'ext-net', it should send traffic to A. It does the IGRP lookup to get to A, and sends the traffic to 'B'. However, since B did not have a BGP session with A, it did not know how to get to the ext-net (in the real case, B was sending traffic back to C since the default route was via C). This is a documented limitation running with "no synchronization". What really make me worried is that there doesn't seem to be way to detect this kind of a problem easily.. how do others monitor their BGP sessions ? "show ip bgp summary". And a little bird tells me that there is MIB in the works... Tony
