RFC4561 · Definition of a Record Route Object (RRO) Node-Id Sub-Object
Definition of a Record Route Object (RRO) Node-Id Sub-Object
In the context of MPLS TE Fast Reroute, the Merge Point (MP) address is required at the Point of Local Repair (PLR) in order to select a backup tunnel intersecting a fast reroutable Traffic Engineering Label Switched Path (TE LSP) on a downstream Label Switching Router (LSR). However, existing protocol mechanisms are not sufficient to find an MP address in multi-domain routing networks where a domain is defined as an Interior Gateway Protocol (IGP) area or an Autonomous System (AS). Hence, the current MPLS Fast Reroute mechanism cannot be used in order to protect inter-domain TE LSPs from a failure of an Area Border Router (ABR) or Autonomous System Border Router (ASBR). This document specifies the use of existing Record Route Object (RRO) IPv4 and IPv6 sub-objects (with a new flag defined) thus defining the node-id sub-object in order to solve this issue. The MPLS Fast Reroute mechanism mentioned in this document refers to the "Facility backup" MPLS TE Fast Reroute method. [STANDARDS-TRACK]
