MS-PW TE and RSVP-TEMotivations Inter-Domain PWs RSVP-TE already supports inter-domain signaling draft-ietf-ccamp-inter-domain-framework-01.txt and draft-ietf-ccamp-inter-domain-rsvp-te-00.txt Not always desirable to setup a direct signaling adjacency between U-PEs Avoid a full mesh of signaling adjacencies between the U-PEs Avoid a full mesh of end-to-end PSN tunnels Instead a U-PE maintains a single adjacency with the neighboring S-PE U-PE/S-PE can establish a RSVP-TE targeted adjacency with the S-PE of the next PSN domain and explicitly route the MS-PW to the destination U-PE
