Abstract:
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
service.
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.
