[j-nsp] RSVP to LDP

[Erdem Sener]

Hi Runt,

 There shouldn't be any problems for both RSVP+LDP running
simultaneously. That said ,I'd suggest to rather
leave the ldp metric alone until you've done configuring LDP on all
the routers, since even with your LDP up
RSVP will have preference over the next-hops anyways.

 Once you have your LDP sessions established and you see the same
amount of routes in your 'show route table inet.3 protocol rsvp'
and show route table inet.3 protocol ldp'  outputs, then you'll be
ready to go deleting your rsvp configuration from the routers in a
quite
relaxed way.

 Cheers,
 Erdem
