The IESG has received a request from the Multiprotocol Label Switching WG (mpls) to consider the following document: - 'LDP Extensions to Support Maximally Redundant Trees' <draft-ietf-mpls-ldp-mrt-06.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2017-09-01. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. 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 (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. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-mpls-ldp-mrt/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-mpls-ldp-mrt/ballot/ No IPR declarations have been submitted directly on this I-D.
