Re: OT: interface HundredGigE0/2/0/0

I'm not an expert on Juniper, but just a comment on cost... for small
installations QFabric is expensive. The fabric interconnect is not cheap.
However, we are doing a comparative design study between Nexus and QFabric
for a new computer room of 100 cabinets - 3200 10G unified ports. Juniper
is *significantly* cheaper. It's possible we have a better discount with
Juniper than with Cisco, but I don't think that's the major difference.

QFabric is basically the same a Nexus 5K/2K fabric extension on a much
larger scale. Just like you wouldn't generally build a data center using
only 5K/2K, you wouldn't build a data center with only QFabric. You want
the big beefy routers (7K or MX) to things like MPLS, L2 interconnects, etc.
