We are getting ppp authentication failure in a ppp over frame relay setup with a carrier using 2 PVCs. One for voice and one for data. Can you provide a sample configuration?

Thank you for responding, but that is how we have it configured and still doesn't work. This router is connected to COVAD's VOA services and we don't know what kind or the configuration of the remote router but if we use an Edgewater router it works fine. We are using a 2431 IAD with 12.4.(4)T4 load. Do you know if there is any bug that could be causing this problem?

can you try without PPP authentication? If this works it should be simple to introduce PAP or CHAP once connectivity is proven.

Please post the output from
#debug ip ppp authentication
