Abstract:
With increasing deployment of Loop-Free Alternates (LFA) [RFC5286],
it is clear that a complete solution for IP and LDP Fast-Reroute is
required. This specification provides that solution. IP/LDP Fast-
Reroute with Maximally Redundant Trees (MRT-FRR) is a technology that
gives link-protection and node-protection with 100% coverage in any
network topology that is still connected after the failure.
MRT removes all need to engineer for coverage. MRT is also extremely
computationally efficient. For any router in the network, the MRT
computation is less than the LFA computation for a node with three or
more neighbors.
