RFC4577 (OSPF as the Provider/Customer Edge Protocol for BGP/MPLS IP VPNs) proposes a mechanism for the use of the Open Shortest Path First V2 ("OSPF", RFC2328) protocol between the Provider Edge ("PE") and Customer Edge ("CE") routers within a BGP/MPLS IP Virtual Private Network ("IPVPN", RFC4364). The standard provides for use of such a provider VPN to join discontiguous locations together, preserving the OSPF area and domain behaviour. This document describes a technique for utilising the same, IPVPN network infrastructure without the requirement to enable the OSPF protocol on the PE/CE interface and thus relieve the PE router of OSPF duties.
