configuring pppoe in cisco CLI (VPDN or bba-group)???

Answered Question
Feb 9th, 2009

Hi All,

My scenario is like below:

Cisco 1841 or 2811 router -- DSL modem --- Aggregation router.

Cisco 1841 or 2811 should initiate a PPPOE to the Aggregation router.

When I started configuring PPPoE, i am not able to find the "protocol pppoe" option under vpdn group. (though on Cisco's FN pppoe-client support is listed on the IOS)

LAB-CE2-1841(config)#vpdn-group 1

LAB-CE2-1841(config-vpdn)#pro

LAB-CE2-1841(config-vpdn)#pro?

% Unrecognized command

LAB-CE2-1841(config-vpdn)#reque

LAB-CE2-1841(config-vpdn)#request-diali

LAB-CE2-1841(config-vpdn)#request-dialin

LAB-CE2-1841(config-vpdn-req-in)#pro

LAB-CE2-1841(config-vpdn-req-in)#protocol ?

l2f Use L2F

l2tp Use L2TP

LAB-CE2-1841(config-vpdn-req-in)#protocol

This above router should initiate a PPPoE to the Aggregation router.

Just came across about the "bba-group pppoe" config CLI. Would like to know currently PPPoE under VPDN is replaced with bba-group CLI.

Or bba-group CLI should only be used on the aggregator side.

Any help is much appreciated.

thanks

Hello Arun,

there was a change and newer IOS versions simply don't need to configure VPDN to support PPPoE client

you need just to configure under fe port

int fe0/0

pppoe-client dial-pool-number 1

+

int dialer

interface Dialer1

ip address negotiated

ip mtu 1492

bba-group is needed if you want to use more then one PPPoE session

Hope to help

Giuseppe
