Arista Layer3

Tue Mar 5 22:46:50 UTC 2019

We have been using the 7280SR-48C6 for 2.5 years now. Just after Arista
announced the full table BGP routing.
Looking at the price / port there is nothing near Arista. We also use Cisco
ASR1K and Juniper MX204 but these have far less capacity.

When we first started, there were quite a few features missing but over the
past 2 year they have really been catching up. I was very happy when they
added MSS clamping at the end of last year.

The new version 7280R2K should be able to handle 2M routes.
