RFC says Tunnel-id uniquely defines a traffic
engineered tunnel. If 2 LSP are part of same traffic
engineered tunnel then tunnel-id is same.So its LSP
ID which varies when 2 paths are set up between
same source and destination.

But isn't this similar to tunnel bandwidth increase
procedure defined in RFC ?.My question is what object
is used to differentiate tunnel bandwidth procedure
and setting up of 2 LSP ? Tunnel bandwidth increase
requires resv with STYLE shared explicit but 2 LSP
set up requires resv with STYLE Fixed Format.

Thanks
Sriram
