[c-nsp] PPPoE related question

[Tseveendorj]

Hello,

I'm trying to do PPPoE on c3825 router but I faced VPDN related problem. 
c3825-ipvoicek9-mz.124-11.T4 IOS has only 2 (PPTP, L2TP) options in 
protocol.

vpdn-group 1
accept-dialin *
* protocol pptp* *
virtual-template 1

I want look like follow.

vpdn-group 1
accept-dialin
**protocol pppoe **
virtual-template 1

The IOS version is c3825-ipvoicek9-mz.124-11.T4 of c3825.
Which IOS version supported *protocol pppoe* command ?

Look forward hearing from you.

Best regards,
Tseveen.
