Abstract:
RSVP-TE Enhancement for MPLS-FRR Bandwidth Optimization is a method of RSVP-TE protocol enhancement for optimizing network resources when FRR is protecting LSP traffic in a topology where the bypass LSP tunnel traverses the original previous hop(s) of the protected LSP. The node providing FRR protection, the PLR, will use the enhanced message TLVs to report to the nodes all the way back to the HE node. The node(s) on the original path prior to the PLR node can check if there is a better alternative bypass tunnel to use to provide FRR from a network resource optimization perspective (such as using the bypass tunnel from the HE node in a ring topology to reduce the traffic in the ring).
