At the risk of the Streisand effect, what am I missing about the Arista
7280QR-C36? It looks like a great router for small ISPs (great price,
large packet buffers, good port selection, meaningful hardware routes).
That said, it looks to be right on the border of DFZ viability. It
supports "over 1M" routes, but I currently have about 1,036,824 in my
route table. How much over is "over"? What happens in EOS when it goes
over?
Arista has FIB compression so depending on what your RIB looks like it
might work out fine. Lots of "it depends".
