Amit,
The answers is .... it depends on how each router is configured.
If each side is configured to authenticate the remote router regardless of
call direction, then the call will fail if authentication on only one side
fails even though each side is performing authentication in a different way.
IF, however, the routers are configured to only authentication depending on
call direction, then a call can succeed depending on the call direction.
For example, let's say R1 is configured to authen using pap on incoming
calls and R2 is also configured to authen on incoming calls but this time
using chap.
In this scenario, it's possible that calls from R1 to R2 fail while calls
from R2 to R1 succeed because only one side is performing authen on any
given call. Make sense?
But, as Brian says, use debug to see this.
HTH, Tim

Subject: PAP and CHAP Ques
Hi Group
In ISDN if we have a router configured for CHAP server and same router
configured for PAP client and on the other side vica versa, then when we
connect both the authentications run. I understand that those will be
separate processes, but suppose if Chap authentication is successful and PAP
is unsuccessful, there would there be a successfull call?
If any type of authentications fails would it disconnect the call or the
call will be established because other type was successful ?
I hope I was able to convey by ques properly.
Thanks
Amit Jain
