Highlights
One common signaling method for different “regions”
Each region may either nest or stitch the inter-region TE LSP into a “different” intra-region TE LSP to carry the end-to-end multi-region TE LSP
RSVP-TE signaling based on LSP Hierarchy (for both nesting and stitching)
Nesting of multiple inter-region LSPs into intra-region LSP
Control and forwarding plane scalability
