Hi Experts

Please help me with this

I have a Scenario

(CE)R1 Fa1/1=================R2 fa1/1 (PE)

R1 is a PPPOE client and R2 is PPPOE server

Query
1. Till the time I do not put the interface on R2 in VRF - PPPOE client gets
and ip from the PPPOE server.
As soon as I put the interface in VRF i cant get the Ip address from the
DHCP server

I have tried it with and without "ip dhcp use vrf connected"
My Current platform is 2851 running
"c2800nm-adventerprisek9-mz.123-14.T7.bin" on both the routers. I have tried
this on a diffent platform as well but nothing works.

Kindly let me know what else do i need to make this work. All you hep is
appreciated. ( Below are the configs from both the sides)

Here are the configs
