Hi

I have read that the 5-tuple {tunnel-endpoint address,tunnel-ID, extended tunnel-ID, sender address, and LSP ID} can uniquely identify an LSP. My question is it locally unique between two nodes or globally unique identifcation

A----B-----C------E
       \     /
         D

For example two LSPs are set up from A to E via the same tunnel. i.e. the have same end points and same path ABDE. Will the 5 tuple uniquely identify any LSP across any two nodes e.g. B and D? Will the values remain same for this LSP across two other nodes in the path e.g. C and E?

Thanks in advance
AN
