[c-nsp] OSPF support to MPLS

[Murilo Antonio Pugliese]

Oliver.

Thanks a lot for you replies. I as aware about MPLS TE restriction with
a multi-area ospf network, ...

Currently, OSPF supports MPLS traffic engineering in only a single area
- typically, the backbone or area 0.

... but right know the environment that I'm considering doesn't consider
employing MPLS TE.

Thanks a lot buddy.

Yours Truly.

forgot to add one thing: MPLS traffic-engineering in a multi-area
network has several restrictions (as the headends no longer have full
visibility), but if you're just using L2VPN or L3VPN, this will continue
to work..
