Lets not forget, the list price for a limited PTX1000 is $650,000. Even
with a substantial 95 percent off list discount, it is nowhere close to the
same ballpark as the Arista solution.

Because Arista has no other routing solution out there, I think they have a
pricing advantage. The spent almost nothing on the hardware since its a
Broadcom Jericho chipset, and can focus on the software. Plus, they don't
have to worry about cannibalizing their routing sales because they only
have one routing product. Unlike Cisco/Juniper, who have to make sure they
don't price their products too low making people jump ship from one of
their routing lines to another.
