[j-nsp] single ip on two interfaces

[Morgan McLean]

I'm making VC's out of all our existing 3300 top of rack switches, as well
as the EX8200 core, resulting in no spanning tree bs, 40gbit lags + lacp to
the tor vc and SRX cluster, plus 2-4gbit lags to the server using lacp
bonding mode.

It works great as long as layer 4 hashing is configured server side to
allow for more than 1gbit between two hosts. Bonding isn't extremely robust
by itself.
