Re: [mpls] [PWE3] Multiple RSVP paths

Hi John,

It is not clear to me 

1) how the proposed solution works in Figure 1 situation of the draft. Even
the receiver B assigns the same label for all five sub-LSPs, because there
are intermediate nodes between A and B, the sender A will be asked to use
the different labels for five sub-LSPs, is that right?  

2) For the following MLSP case, do sub-LSPs start from node A or from node
W?

                           --L--   --P-- 
                          /     \ /     \
                  A------W       S---Q---B
                          \     / \     /
                           --M--   --R-- 

Thanks,
Lucy
