[j-nsp] Adaptive LSPs

[Craig Pierantozzi]

Adaptive allocates a reservation for each RSVP session (shared explicit). 
This means when configuring standby secondary paths, shared links
can be used for the primary and the secondary.  Depending on 
how you are designing your MPLS network this may not be 
optimal.  Some people do not want secondary paths signaled
over the same link as the primary for restoration reasons. 

So it depends on the network topology and what the requirements
are for the design that could be a con.
