OSPF-TE Extensions in Support of Shared Mesh Restoration
This document describes extensions to the OSPF-TE routing protocol in support of path computation for shared mesh restoration. New optional sub-TLVs are added to the link TLV of the Traffic Engineering (TE) LSA so that the sharing information of the restoration resource on the TE link reserved for shared mesh restoration is disseminated. The extensions supports both SRLG-disjoint and node-disjoint paths.
