I had a config working great on my 2811, so I thought it should work on a 2821 . Below is the config
Router#sh run

I copied it line by line, but I'm not able to establish a connection with the Centurylink ONT on the 2821. I forgot how I was able to establish a pppoe client on the fa0/0.1...so I believe that is the problem..below is the config for the 2821
