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.
