[f-nsp] FES-XE Performance Q

[Jason J. W. Williams]

Hi Niels,

Thank you for the detailed response. The FES-XE can hold 1M entries in
its RIB and 500K in its FIB, so I think from that point of view it
will barely let us cram in full routes from three peers. Otherwise, I
think we have to consider an MLX-4 or a Juniper M7i.

-J
