Thanks Guys,
It worked with BVI on both ends and IRB on the central one. Got the point from
Dimitry on BVIs
at R1 and R3 but it is working only when I put in R2 - IRB, bridge 1 bridge ip.
Any idea why IRB is required in R2?. It is supposed to be only a bridge, right?
Cheers
Sarangan

Hi,
I've tried with IRB enabled on R2 (without BVI) - it worked.
Try clear arp on R1 or R3 it may help.
Not 100% sure, but I guess the reason, why BVI on R1 and r3 are necessary,
is because mac-address xxxxxxxxxxxx under serial int doesn't work.
Router accepts it but I don't see it under sh int serial 0
BVIs on R1 and r3 are not necessary if you use ethernet interfaces on r1 and
r3.

Hi ;
it didnt work with me without using BVI on R2 .
still i dont know what is the idea behind creating BVI on R1 and R3 .
why it didnt ping from the begining .
