draft-li-mpls-proxy-te-lsp-00IETF 87 MPLS2 Introduction [I-D. draft-li-mpls-seamless-mpls-mbb-00 ] introduced the framework and requirement of Seamless MPLS for mobile backhaul networks. The draft is to provide a method, Proxy TE, to setup proxy egress MPLS TE LSP with RSVP-TE which could stitch with BGP LSP to form an end-to-end LSP.  Define a new RSVP-TE object: Proxy Destination Object  Procedures of Setup Proxy TE LSP

draft-li-mpls-proxy-te-lsp-00IETF 87 MPLS3 Requirement on Proxy Egress MPLS TE LSP Proxy egress MPLS TE LSP has to be setup in mobile backhaul networks to stitch BGP LSP for Seamless MPLS.

draft-li-mpls-proxy-te-lsp-00IETF 87 MPLS5 Procedures Ingress: Use the proxy destination address to calculate path and the setup procedure is the same as current process. Egress: Identify itself as the proxy node, stitch the proxy RSVP-TE with the other LSP, return RESV message with the same proxy destination object. AN P AGN Remote AN LSP Path message Resv message PATH message Session Object : tunnel end point address = Remote AN Proxy Destination Object : proxy destination address = AGN PATH message Session Object : tunnel end point address = Remote AN Proxy Destination Object : proxy destination address = AGN PATH message Session Object : tunnel end point address = Remote AN Proxy Destination Object : proxy destination address = AGN PATH message Session Object : tunnel end point address = Remote AN Proxy Destination Object : proxy destination address = AGN RESV message Proxy Destination Object : proxy destination address = AGN RESV message Proxy Destination Object : proxy destination address = AGN RESV message Proxy Destination Object : proxy destination address = AGN RESV message Proxy Destination Object : proxy destination address = AGN
