[OSPF] RFC 4577 Query

["Lokesh Jain" <jainlokesh at gmail.com>]

Hi All,

In RFC 4577 it states that earlier PE-CE link used BGP but to provide certain advantages to customer, OSPF would be a better choice between PE-CE link.
But to do that we have to modify BGP /OSPF interaction so that routes are distributed as inter-area routes and not as AS-External routes. 

My doubt is:

In earlier scenario, CE would be running an instance of BGP and some other IGP, say OSPF. In that case also the routes distributed in a customer VPN site would be AS-External routes and not inter-area routes. How was that handled in previous case? Or is it the just the case of moving BGP/OSPF interaction from CE to PE?

Please guide me regarding this. I must be missing on some point here.
