During the 3 minutes of the session holding up, do you see any packets in the OutQ (show ip bgp summ)
Neighbor V AS MsgRcvd MsgSent TblVer InQ OutQ Up/Down State/PfxRcd 172.16.2.1 4 64900 1754971 1714093 1406547 0 0 7w2d 8 As has been fairly pointed out, it looks like your 'fat' update packets are likely dropped by either an MTU mismatch or a CoPP filter on the other side. Its hard to know either way without further debugging (debug ip bgp update) run during your off-hours Shaan _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
