There're 5 tuples in rsvp object that should be used to differentiate lsp:
 	Tunnel endpoint (egress) address (in SESSION object)
 	Tunnel ID (in SESSION object)
 	Extended Tunnel ID (in SESSION object)
 	Sender (ingress) address (in SENDER_TEMPLATE/FILTER_SPEC object)
 	LSP ID (in SENDER_TEMPLATE/FILTER_SPEC object

In one platform,even when ingress and egress destination is the same,
tunnel-id/lsp-id pairs is unique. Tunnel-id (and/or lsp-id) may also 
increasing if lsp is flapping.

Thanks,

Carlos
