   This document specifies extensions to OSPF to support the distributed
   computation of Maximally Redundant Trees (MRT).  Some example uses of
   the MRTs 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 transitioning of
   capabilities.  An extension is introduced to flood MRT-Ineligible
   links, due to administrative policy.

   The need for a mechanism to allow routers to advertise a worst-case
   FIB compute/install time is well understood for controlling
   convergence.  This specification introduces the Controlled
   Convergence TLV to be carried in the Router Information LSA.
