Thanks for your input but both options didn't quite work.
Maybe I made a mistake in explaining the questions.
Old EBGP config
Router A in AS 5
Router B in AS 10
Neigbor relationship between the two AS'es are formed.
New admin takes over Router A and gets assigned new AS 110.
New Admin does not have the old bgp config.
New admin wants to form a neighbor relationshiop with B and knows B's has AS 10.
Here is the bgp config of A
router bgp 110
bgp router-id x.x.x.x
no auto-summ
neighbor b.b.b.b remote-as 10
neighbor b.b.b.b ebgp-multihop 5
neighbor b.b.b.b update source e0
neighbor b.b.b.b local-as ????
Mind you Router B's config hasn't changed and is still trying to connect back to Router A's old AS.
??? stands for router A's old AS.
Since the admin doesn't know the old AS for Router A to which router B had a neighbor relationship, he is stumped.
I have tried the debug ip bgp and also changing the remote AS to a higher number but I still don't get the message which would give out the AS router B is trying to connect to.
i.e there is a command on router B as follows :
neighbor a.a.a.a remote-as xxxx
I hope I have explained this right ..
Any more insight into finding out the AS ...
