"draft-ietf-l3vpn-ospf-2547-00.txt", specifies that MP-BGP creates VPN-IPV4 route for a route learnt from CE where PE-CE link uses OSPF.
VPN-IPV4 route attaches "OSPF router ID", "OSPF route type " and "OSPF domain ID" extended communities.This is to allow this route to be converted back into OSPF route transperantly.
Why does one need to attach "OSPF router id" ?Is this attribute  used by the remote PE?
 
thanks.
Rahul
