Hi Loa,

I've read this document and think it provides a useful function for reducing the data plane state of RSVP-TE LSPs. Thus I support the adoption.

I concur with Lou's concern about the TE bandwidth/tspec/rspec processing, the impact of shared label on this needs to be specified. 

I also have some concerns about the automatic delegation process described in section 5.3, maybe I need to reread it, but it seems that in some cases the mechanism may not result in an appropriate set of delegation nodes. And what would happen if the ETLD value in the received PATH message is bigger than the maximum number of labels this node can handle? It seems this case was not covered in section 5.3.

It would be great if the above concerns could be considered either before or after the adoption. 

Best regards,
