[f-nsp] mpls + bgp support on NI CES2K

[Youssef Bengelloun-Zahr]

Hello,

I would agree on the "basically".

As someone pointed out before, there are some caveats / limitations between the two platforms. The way I see it :

- CER : entry-level MPLS PE,

- MLXe : high-level MPLS PE,

My 2 cents.

Y.
