Well thats what the routers are telling me, setting a higher AS-Number than
the local one would generate the output needed
For Example:
In As 4 is R4 --- R3 is in As 3
Lets say I miss configure R3
At R3 I get this
BGP: 3.3.4.4 bad OPEN, remote AS is 4, expected 44
BGP: 3.3.4.4 went f
R3(config-routrom OpenSent to Closing
%BGP-3-NOTIFICATION: sent to neighbor 3.3.4.4 2/2 (peer in wrong AS) 2 bytes
0004 FFFF FFFF FFFF FFFF FFFF FFFF FFFF FFFF 002D 0104 0004 00B4 0A07 0101
1002 0601 0400 0100 0102 0280 0002 0202 00
And in R4 I only get this
R4(config-router)#
*Mar 1 01:48:04.959: %BGP-3-NOTIFICATION: received from neighbor 3.3.3.3
2/2 (peer in wrong AS) 2 bytes 0004
0004h = 4, R4 AS Number the output show nothing more than that!
Now if At R4 I set this
R4(config-router)#neigh 3.3.3.3 remote-as 65535
*Mar 1 01:50:48.459: BGP: 3.3.3.3 bad OPEN, remote AS is 3, expected 65535
*Mar 1 01:50:48.459: BGP: 3.3.3.3 went from OpenSent to Closing
*Mar 1 01:50:48.459: %BGP-3-NOTIFICATION: sent to neighbor 3.3.3.3 2/2
(peer in wrong AS) 2 bytes 0003 FFFF FFFF FFFF FFFF FFFF FFFF FFFF FFFF 002D
0104 0003 00B4 0303 0303 1002 0601 0400 0100 0102 0280 0002 0202 00

Victor,
Is it required to set the neighbor as "higher" then the unknown side?
Does that make a difference in the output?
Thanks in advance,
Paul
