OSPFv3 as a Provider Edge to Customer Edge (PE-CE) Routing Protocol
Abstract
Many Service Providers (SPs) offer Virtual Private Network (VPN)
services to their customers using a technique in which Customer Edge
(CE) routers are routing peers of Provider Edge (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. Support currently exists for both IPv4 and IPv6
VPNs; however, only Open Shortest Path First version 2 (OSPFv2) as
PE-CE protocol is specified. This document extends those
specifications to support OSPF version 3 (OSPFv3) as a PE-CE routing
protocol. The OSPFv3 PE-CE functionality is identical to that of
OSPFv2 except for the differences described in this document.
