[c-nsp] RPR+ restrictions

[Sukumar Subburayan]

The simplest thing you can do is to have a Gigabit channel between the sup 
uplinks and connect it to your backbone. So, when one sup fails the other 
sup takes over and the 2nd port in the channel on the newly active sup is 
still connected to the backbone.

Also, note that although MPLS doesn't support SSO/NSF, it doesn't mean 
that the system will go to RPR+ mode. It means that MPLS protocol related 
stuff will not be stateful. All other SSO/NSF supported features will be 
stateful.
