Hi all,
This draft is to collect all possible solutions to reach a most optimized 
one. In this 00 version of the draft, we got an alternative option at 
appendixB, and give a brief comparison between the two options. For better 
backward compatibility, we still keep the "label request message" option. 
If you have any preference or comments about the two options, please tell 
us.

Also cc to MPLS WG, to ask for comments about the FEC128/129 update in 
current draft. There are many parameters in FEC128/129 which is not like 
prefix-FEC. In this draft, if a PE receives a label mapping with same FEC 
parameter and label, but only different Cbit value than previously 
received, then PE will update this FEC with new Cbit value.

Thanks
Lizhong
