RE: RFC1483 Bridging

OK, looking thru your configuration.

You need to have a pvc with the vpi/vci and under this apply
pppoe-client dial-pool-number 1

You will need to find the pvc information from your provider.

Hi Nish ,

THe problem I am seeing is that PPP never kicks in. Dialer is not initiating
the PPP Session because it thinks that Dialer string is not set.

I understand if PPP authentication is the problem I would have got the PPP
debugs which would clearly tell me that authentiation has indeed failed.

Having said that I did change the configuration and found that nothing
changed
after enabling PAP ( as per your instruction ). Moreover I stuck the configs
on the ATM interface ( WIC1-ADSL on 1841 ) , there is not problem in getting
authenticated via CHAP . I removed the bridging on Modem and applied the
same
user name and password on the MODEM , it worked absolutely fine. It appears
to
me that this is not a PPP issue but a dialer issue. But I could not figure
out
why dialer is looking for a dialer string for initiating PPP.

Thanks and Regards

Arun
