A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Multiprotocol Label Switching Working Group of the IETF. Title : LDP Extensions to Support Maximally Redundant Trees Authors : Alia Atlas Kishore Tiruveedhula Chris Bowers Jeff Tantsura IJsbrand Wijnands Filename : draft-ietf-mpls-ldp-mrt-00.txt Pages : 16 Date : 2015-01-08 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 LDP MT-ID space.
