Correct.  Don't forget, however, that the session object has three 
values - destination address, tunnel ID and extended tunnel ID, and the 
sender template has two values - sender address and LSP ID.

If the two LSPs are going to be in different sessions, then they will 
have different tunnel IDs.

If they are in the same session, then they will have to have different 
LSP IDs.

See above.  They will have different tunnel IDs, if they are in 
different sessions, or different LSP IDs if they are in the same session.

Yes.
