Technical Summary
The document specify an extensions to the Label Distribution
Protocol (LDP) that support the creation of label-switched paths
for Maximally Redundant Trees (MRT). The most obvious use of MRT
is for Fast-Resoute for IP/LDP uni- and multicast. This is
referred to as MRT-FRR.
This document specifies the ability of LDP to advertise MRT
Capability and the associated behavior expected for LSRs (Label
Switching Routers) and LERs (Label Edge Routers) 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.
Working Group Summary
The working group supported this document. The progress was a
bit slow, since we were waiting for other MRT documents in
other working groups.
Document Quality
We are aware of two prototype implementations of this protocol
specification. An implementation poll has been sent out to the
working group, as soon as we have more information we will update
the shepherd write-up.
The document has been through the normal wg process, no other types
are necessary.
