Multicast VPN State Damping
RFC 7899, “Multicast VPN State Damping”, is a Proposed Standard document published in June 2016 by T. Morin, S. Litkowski, K. Patel, Z. Zhang, R. Kebler, J. Haas. It updates RFC 6514. The canonical text is published by the RFC Editor.
Abstract
This document describes procedures to damp Multicast VPN (MVPN) routing state changes and control the effect of the churn due to the multicast dynamicity in customer sites. The procedures described in this document are applicable to BGP-based multicast VPN and help avoid uncontrolled control-plane load increase in the core routing infrastructure. The new procedures proposed were inspired by BGP unicast route damping principles that have been adapted to multicast.
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.
