Technical Summary
The initial BGP/MPLS IP VPN specification enabled PE routers to learn routes
within customer sites through static routing, or through a dynamic routing
protocol instantiated on the PE-CE link.
Specifically, RFC4364 includes support for dynamic routing protocols such as
BGP, RIP, and OSPFv2. The OSPFv2 as the Provider/Customer Edge Protocol for
BGP/MPLS IP Virtual Private Networks specification (RFC4577) further updates the
operation of OSPFv2 as the PE-CE routing protocol by detailing additional
extensions to enable intra-domain routing connectivity between OSPFv2-based
customer sites.
This document defines the mechanisms required to enable the operation of OSPFv3
as the PE-CE Routing Protocol in BGP MPLS/IP VPNs. In doing so, it reuses, and
extends where necessary, the "BGP/MPLS IP VPN" method for IPv6 VPNs defined in
RFC4659, and OSPFv2 as the PE-CE routing protocol defined in RFC4577. This
document also includes the specifications for maintaining intra-domain routing
connectivity between OSPFv3-based customer sites across a SP backbone.
