1. Applicability of LDP Multi-Topology for Unicast Fast-reroute Using Maximally Redundant Trees
Publication: IETF Individual Draft
Publication History: 2012-10
Publication URL: https://tools.ietf.org/html/draft-li-rtgwg-ldp-mt-mrt-frr-00
Description:
In this document, we analyze the applicability of the LDP multi- topology(MT) for unicast fast-reroute using Maximally Redundant Trees(MRT) . We analyze the label allocation behavior and label forwarding entry setup with LDP Multi-Topology when MRT fast-reroute is used. Different application scenarios are considered and guidance on the applicability of LDP MT for unicast fast-reroute using MRT is provided.
2. Routing Extension for Fast-Reroute Using Maximally Redundant Trees
Publication: IETF Individual Draft
Publication History: 2012-10
Publication URL: https://tools.ietf.org/html/draft-li-rtgwg-igp-ext-mrt-frr-00
Description:
The document proposes the routing protocol extension and procedures to support fast reroute using maximally redundant trees.
3. Intermediate System to Intermediate System (IS-IS) Extensions for Maximally Redundant Trees (MRT)
Publication: IETF WG Draft
Publication History: 2015-02
Publication URL: https://tools.ietf.org/html/draft-ietf-isis-mrt-00
Description:
This document describes necessary extensions to IS-IS to support the distributed computation of Maximally Redundant Trees (MRT). Some example uses of the MRTs include IP/LDP Fast-Reroute and global protection or live-live for multicast traffic. The extensions indicate what MRT profile(s) each router supports. Different MRT profiles can be defined to support different uses and to allow transition of capabilities. An extension is introduced to flood MRT- Ineligible links, due to administrative policy.
4. OSPF Extensions to Support Maximally Redundant Trees
Publication: IETF WG Draft
Publication History: 2015-01
Publication URL: https://tools.ietf.org/html/draft-ietf-ospf-mrt-00
Description:
This document specifies extensions to OSPF to support the distributed computation of Maximally Redundant Trees (MRT). Some example uses of the MRTs include IP/LDP Fast-Reroute and global protection or live- live for multicast traffic. The extensions indicate what MRT profile(s) each router supports. Different MRT profiles can be defined to support different uses and to allow transitioning of capabilities. An extension is introduced to flood MRT-Ineligible links, due to administrative policy. The need for a mechanism to allow routers to advertise a worst-case FIB compute/install time is well understood for controlling convergence. This specification introduces the Controlled Convergence TLV to be carried in the Router Information LSA.
