I'm having a problem with an 871 router that I need to configure with DMVPN, but I cannot get it to work using a bridge dsl modem using pppoe on 871 as a client. It will not authenticate. I will attach a log from doing a debug ppp authentication. Here is the running config:

recreate the username and password and then try again. The logs show a possiblity ok authentication mismatch.

If possible try a debug of PPP and see what's happening
