   TRILL protocol provides multicast data forwarding based on IS-IS link
   state routing. Distribution trees are computed based on the link
   state information through Shortest Path First calculation. When a
   link on the distribution tree fails, a campus-wide recovergence of
   this distribution tree will take place, which can be time consuming
   and may cause considerable disruption to the ongoing multicast

   This document specifies how to build backup distribution trees to
   protect links on the primary distribution tree. Since the backup
   distribution tree is built up ahead of the link failure, when a link
   on the primary distribution tree fails, the pre-installed backup
   forwarding table will be utilized to deliver multicast packets
   without waiting for the campus-wide recovergence. This minimizes the
   service disruption. This document updates RFC 6325.
