>Abstract:
>   TRILL protocol provides layer 2 multicast data forwarding using IS-IS
>   link state routing. Distribution trees are computed based on the link
>   state information through Shortest Path First calculation and shared
>   among VLANs across the campus. 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 proposes to build the backup distribution tree 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, which minimizes the
>   service disruption.
