Group,
Thanks to all those who replied.I added the "Area 0
authetication message-digest" on R12 as u people said
and it works though i had to reboot in the process.
The Virtual Link authentication was not working.Will
also look into the 11.X and 12.X compatibility
problems.
Thanks once again to all.
