MRT OAM Requirements and Use cases
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-FRR creates two alternate trees separate from the primary next- hop forwarding used during stable operation. These two trees are maximally diverse from each other, providing link and node protection for 100% of paths and failures as long as the failure does not cut the network into multiple pieces. This document spcifies how data plane protocols can be applied to operations and maintenance procedures for MRT. The document is structured to outline how Operations and Management functionality can be used to assist in fault management.
