Re: stub area in a vrf

[John Pecola <[e-mail]>]

I think Manis' result were based on tests on a
specific vendor's box and that is why the result.
Otherwise as mentioned by Acee and Rob, there is
nothing stopping the PE-CE link to be in a stub in the
2547 case also since a PE should(must?) behave as an
ABR and can originate a default into the stub.

Thanks
John

I agree. However, I'd say that even if the PE router
is not connected to
multiple areas it should behave as if it one and
originate the default. It can use
the OSPF route type in advertised with the BGP
extended community to determine
which routes to advertise into the stub area.

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
