Extranet Multicast in BGP/IP MPLS VPNs
RFC 7900, “Extranet Multicast in BGP/IP MPLS VPNs”, is a Proposed Standard document published in June 2016 by Y. Rekhter, E. Rosen, R. Aggarwal, Y. Cai, T. Morin. It updates RFC 6513, RFC 6514, RFC 6625. It has since been updated by RFC 8534. The canonical text is published by the RFC Editor.
Abstract
Previous RFCs specify the procedures necessary to allow IP multicast traffic to travel from one site to another within a BGP/MPLS IP VPN (Virtual Private Network). However, it is sometimes desirable to allow multicast traffic whose source is in one VPN to be received by systems that are in another VPN. This is known as a "Multicast VPN (MVPN) extranet". This document updates RFCs 6513, 6514, and 6625 by specifying the procedures that are necessary in order to provide extranet MVPN service.
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.
