Doubt regarding the control channel seperation in GMPLS CR-LDP.



Hello,
I have a couple of doubts regarding the control channel seperation in GMPLS CR-LDP (draft-ietf-mpls-generalized-cr-ldp-05.txt). For simplicity let me consider a scenario of setting up a uni-directional path between two nodes having seperate data channel and control channel and neither link bundling nor unnumbered links is being considered.
1) What is the significance of IPv4 next hop address in the Interface ID TLV? Is this the next hop address for a Forwarding Equivalence Class(FEC) F1?
2) What does the Logical Interface ID in the Interface ID TLV specify? Is this the interface ID of the control channel at the downstream LSR? If yes how does the upstream node know about it in prior?
3) How does the upstream LSR knows about the data channel id at the downstream node, since the draft mentions data channels are specified from the view point of the sender of the Mapping message i.e. downstream node.
 
Thanks in advance for your reply.
Regards
Vinay
