Hi Guys,
Someone has asked me if the following scenario is "Solvable"
R1 (IP:1.1.1.1)
----------------------
router bgp 100
neighbor 2.2.2.2 remote-as 200
R2 (IP:2.2.2.2)
----------------------
router bgp 200
neighbor 1.1.1.1 remote-as 500 <---(intentional-mistake!)
Assuming that R1 does not know what the AS# that was configured on R2 - (if
R1 knows then it can use the "neighbor 2.2.2.2 local-as 500" command to
resolve the problem) - how can you figure out what AS# was configured on R2
so u can establish relationship?
Note: "debug ip bgp detail" won't show you that!
I tried to see IF the "wrong AS# 500" shows up in any of the communications
debugs between R1 and R2 when they hardly try to establish the relationshops
but i could not succeed!! Is it really possible to detect what AS# the
remote router has configured for our router?
Best Regards,
Digital
