    Vol II Lab 2 - Section 1.6 - PPPoE

    Reply Contact

    Going through the documentation on Cisco's site, I came up with another solution for R6 in this section:

     

    Here is the config I applied to R6 and it works just fine - R5 calls in using its Dialer profile.  This should meet all the requirements of that section.

    I'm posting this because I saw references all over the place that made me believe the VPDN config is the 'old' way of doing this.  R6 is a 3640 running 12.3(8)T11 IOS.

    this is depending on the IOS which u r using, sometimes PPPoE encapsulation is not available under vpdn-group so you have to use bba-group....

    Thanks for the reply!  What I was suggesting though is that the VPDN config is the 'old' way of doing it.  Newer IOS' should support the bba-group command.

    Hint - it is good to know either way of configuring this feature :)

    You should be able to configure it either way.  In new IOS versions if you use the VPDN-group it should automatically change it to the bba-group in the config.

    Hi Brian,

    When I was using Internetwork expert racks for this lab I tried to use vpdn-group but I could not find pppoe as an option in the protocol command. It took me a lot of time to know that bba-group should be used, I dont remeber what is the IOS which is being used in IE racks for R3 and R5.

    I am using Version 12.3(14)T7 for my dynamips and it works fine with vpdn-group.

    Rack1R3(config-vpdn-acc-in)#protocol ?
      any    Use any protocol
      l2f    Use L2F
      l2tp   Use L2TP
      pppoe  Use PPPoE
      pptp   Use PPTP


    BR,
    Mohammed Samir
