Hi, I think in CR-LDP you may use LSP-ID TLV, which will give you the tunnel ingress and the LSP ID. And in RSVP-TE you may use the Sender Template Object, which will give you the same information. RRO may also be used in RSVP-TE, however you only will get the ingress LSR information that you need, but not which LSP it is coming from.
