Encoding Multipoint LDP Forwarding Equivalence Classes in the NLRI of BGP MCAST-VPN Routes
RFC 7441, “Encoding Multipoint LDP Forwarding Equivalence Classes in the NLRI of BGP MCAST-VPN Routes”, is a Proposed Standard document published in January 2015 by IJ. Wijnands, E. Rosen, U. Joorde. It updates RFC 6514. The canonical text is published by the RFC Editor.
Abstract
Many service providers offer "BGP/MPLS IP VPN" service to their customers. Existing IETF standards specify the procedures and protocols that a service provider uses in order to offer this service to customers who have IP unicast and IP multicast traffic in their VPNs. It is also desirable to be able to support customers who have MPLS multicast traffic in their VPNs. This document specifies the procedures and protocol extensions that are needed to support customers who use the Multipoint LDP (mLDP) as the control protocol for their MPLS multicast traffic. Existing standards do provide some support for customers who use mLDP, but only under a restrictive set of circumstances. This document generalizes the existing support to include all cases where the customer uses mLDP, without any restrictions. This document updates RFC 6514.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
