Abstract:
This document specifies extensions to the Label Distribution
Protocol(LDP) to support the creation of label-switched paths for
Maximally Redundant Trees (MRT). A prime use of MRTs is for unicast
and multicast IP/LDP Fast-Reroute, which we will refer to as MRT-FRR.
The sole protocol extension to LDP is simply the ability to advertise
an MRT Capability. This document describes that extension and the
associated behavior expected for LSRs and LERs advertising the MRT
Capability.
MRT-FRR uses LDP multi-topology extensions and requires three
different multi-topology IDs to be allocated from the MPLS MT-ID
space.
