question about PPPoe client configuration

[west33637]

With a router running 12.4T IOS configured as a PPPoE client

do we still need to configure the VPDN commands on the client side?

I was able to get PPPoe to work without the VPDN commands (sh pppoe session showed the session up on both sides). however, I was unable to receive a DHCP address on the dialer interface from the PPPoe server no matter what I tried (including adjusting the MTU). When I put in a static IP on the dialer interface I was able to ping the PPPoe server with no issue, so it was not a reachability issue. The PPPoe client and server were  in the same broadcast domain.

Dear

,

VPDN commands are not a must on client side. See the below link

The problem in receiving IP on the client side may be due to the local pool config. on VPDN server .See a sample config for VPDN server

vpdn enable
!
vpdn-group 1
accept-dialin
  protocol pptp
  virtual-template 1
!

interface Virtual-Template1
ip unnumbered Loopback1
peer default ip address pool test
ppp authentication pap chap

ip local pool test 192.168.222.240 192.168.222.245

Hello Haris. Thanks for the response. Per my earlier post, I was using DHCP and not IPCP to get the ip address. DHCP was configured correctly on the server and client side. Its hard to screw up a DHCP configuration.
