   This document describes extensions to IS-IS to support the
   distributed computation of Maximally Redundant Trees (MRT).  Example
   uses of MRT include IP/LDP Fast-Reroute and global protection or
   live-live for multicast traffic.  The extensions indicate what MRT
   profile(s) each router supports.  Different MRT profiles can be
   defined to support different uses and to allow transition of
   capabilities.  An extension is introduced to flood MRT-Ineligible
   links, due to administrative policy.  This document also defines the
   Controlled Convergence sub-TLV, which is useful for MRT FRR as well
   as other applications.
