Hi Jonathan:

Thanks a lot for your profound reply. It's much appreciated.

The follow-up question that I've is that, can we still assign a local link 
ID independently of the TE Link ID to an unbundled TE Link (A TE Link with 
only one component link)? In which case, TE Link ID will be an addressable 
entity and component link ID will be a locally assigned identifier. Do you 
think if such an assignment is made, the neighboring nodes have to implement 
link bundling support (as mentioned in draft-ietf-mpls-bundle-00.txt? Or 
there are no pit-falls associated with assigning TE link ID and component 
link ID independently, for unbundled interfaces.

Thanks in advance.
