Hi John, Mani,

What if the VRF was an ABR, and simply supplied a default route to the CE in
the stub?

I think this should work and allow the PE-CE link be part of a stub area.

Thanks,
Rob.

Hi Jonh,
 I tried to do similar kind of testing, that is configuring PE-CE link as
stub. But as PE will be ASBR, we cannot configure  it in a stub.

rfc 2328: Section 3.6
 AS boundary routers cannot be placed internal to stub  areas.

Thanks,
Mani
