Ranjith,
Let me teach you a trick to tackle similar problems. If you do
not know the AS # of the remote peer, turn on notification on the router and
you will see a similar message:
*Sep 30 11:37: 40.741: %BGP-3-NOTIFICATION: sent to neighbor 10.10.10.2 2/2
(peer in wrong AS) 2 bytes *0384
*FFFF FFFF FFFF FFFF FFFF FFFF FFFF FFFF 002D 0104 0384 00B4 9601 0202 1
002 0601 0400 0100 0102 0280 0002 0202 00
The Hex Value in the Bold will actuall tell you the right AS you should be
peering with ;-)
You can use the Calculator in Windows XP in scientific mode, enter this
value and then just hit decimal value to get the AS value in decimals.
HTH,
Tarun
