2. 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

5. 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
