OSPF will NOT work... It is the BGP community values that allow you to
properly filter the routes into the correct VRF. Think of the VRF as a
mini-routing-table... If you have different customers with the SAME IP
routes, OSPF (or "regular" BGP setup, or any routing protocol for that
matter) would fail. You'd have multiple destinations to IP routes, and your
customers would be very upset. :)
You need MBGP for some additional "address family" features that have been
added.

Subject: RE: [nsp] REG: MPLS based VPN's
Hi All,
Thanks a lot for all the advice, Further I would like to clarify a few
more queries. In an MPLS network, I do understand that the edge routers have
a VRF, which is a subset of the routes belonging to a VPN. Now how is the
VRF distributed to other routers, Do I need to use MBGP, or else will OSPF
do the job.
Kindly advice
With warmest regards,
Vinod.
