Abstract:
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.
