Explicit Tracking with Wildcard Routes in Multicast VPN
RFC 8534, “Explicit Tracking with Wildcard Routes in Multicast VPN”, is a Proposed Standard document published in February 2019 by A. Dolganow, J. Kotalwar, E. Rosen, Z. Zhang. It updates RFC 6514, RFC 6625, RFC 7524, RFC 7582, RFC 7900. The canonical text is published by the RFC Editor.
Abstract
The base Multicast VPN (MVPN) specifications (RFCs 6513 and 6514) provide procedures to allow a multicast ingress node to invoke "explicit tracking" for a multicast flow or set of flows, thus learning the egress nodes for that flow or set of flows. However, the specifications are not completely clear about how the explicit tracking procedures work in certain scenarios. This document provides the necessary clarifications. It also specifies a new, optimized explicit-tracking procedure. This new procedure allows an ingress node, by sending a single message, to request explicit tracking of each of a set of flows, where the set of flows is specified using a wildcard mechanism. This document updates RFCs 6514, 6625, 7524, 7582, and 7900.
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.
