Extending RSVP-TE to support inter-AS LSPs
Cristel Pelsser and Olivier Bonaventure
Multiprotocol Label Switching (MPLS) is currently used inside Autonomous
Systems (ASs) for Virtual Private Networks (VPNs) or Traffic Engineering
purposes. We first discuss the Service Provider's requirements for the
utilization of MPLS Label Switched Paths (LSPs) across AS boundaries.
Then we propose a minimum set of extensions to RSVP-TE that allow
to establish inter-AS LSPs in accordance with the SPs' requirements. We
also show how LSP protection techniques can be extended to provide
link or node failures protection for the inter-AS links and border routers.
