[c-nsp] ospf authentication

[Collins Richard, SLC SBS ITO (SHA)]

Yes authentication will only then take effect.  I just wouldn't know which
area 0 is the 'real' area 0 during the transition-the area 0 which is still
operating without authentication or the area 0 which is now doing
authentication.

It's not until I add "area 0 authentication message-digest" into our "router
ospf 1" section that this actually takes effect right?
