Many Service Providers offer Virtual Private Network (VPN) services
to their customers, using a technique in which customer edge routers
(CE routers) are routing peers of provider edge routers (PE
routers). The Border Gateway Protocol (BGP) is used to distribute
the customer's routes across the provider's IP backbone network, and
Multiprotocol Label Switching (MPLS) is used to tunnel customer
packets across the provider's backbone. This is known as a "BGP/MPLS
IP VPN". The base specification for BGP/MPLS IP VPNs presumes that
the routing protocol on the interface between a PE router and a CE
router is BGP. This document extends that specification by allowing
the routing protocol on the PE/CE interface to be the Open Shortest
Path First (OSPF) protocol.
This document updates RFC 4364. [STANDARDS TRACK]
