   This document specifies extensions to the Label Distribution
   Protocol(LDP) to support the creation of label-switched paths for
   Maximally Redundant Trees (MRT).  A prime use of MRTs is for unicast
   and multicast IP/LDP Fast-Reroute, which we will refer to as MRT-FRR.

   The sole protocol extension to LDP is simply the ability to advertise
   an MRT Capability.  This document describes that extension and the
   associated behavior expected for LSRs (Label Switching Routers) and
   LERs (Label Edge Routers) advertising the MRT Capability.

   MRT-FRR uses LDP multi-topology extensions and requires three
   different multi-topology IDs to be allocated from the MPLS MT-ID
