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.

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. ----- Original Message ----- From: Robert Pineau To: OSPF@PEACH.EASE.LSOFT.COM Sent: Thursday, July 29, 2004 9:35 AM Subject: Re: stub area in a vrf 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.

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.
