Technical Summary

   This document describes procedures to damp multicast VPN 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.  New procedures are proposed inspired from BGP
   unicast route damping principles, but adapted to multicast.

Working Group Summary

  This Document has been presented several times before the WG at 
  IETF meetings.  There was good support to adopt it as a WG Document.
  There have been fewer opinions expressed at the time of WG Last Call.

Document Quality

   There are no current implementations, but one seems to be planned.
