2921 Problem with VDPN and PPPoE

Unanswered Question
Sep 6th, 2010

Hello Folks,

Customer's got a problem.

He can't configure "protocol pppoe" on his 2921 in a VDPN group.

/* Style Definitions */ table.MsoNormalTable {mso-style-name:"Normale Tabelle"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin:0cm; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman","serif";}

vpdn-group test


protocol x <---- only l2tp or pptp are available, but no pppoe

I've searched the whole internet for a reason/solution but couldn't find anything...

My guess would be that he needs another IOS w/ another feature-set.

Can somebody enlighten me?

Kind Regards,


I have this problem too.

Hello Tim,

In recent IOSes, the PPPoE access is configured under bba-group and not under a vpdn-group anymore.

This can be an example:

vpdn enable

bba-group pppoe global

virtual-template 1

If the PPPoE session has to be further forwarded via L2TP, an additional vpdn-group must be configured for this but to create a simple PPPoE concentrator, this configuration should work (note you still have to create the virtual-template interface referred to in the bba-group config).

Best regards,
