The OS supports it, but I wonder if that command is supported on that hardware or if there are other requirements to make that a go. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest-IX http://www.midwest-ix.com ----- Original Message ----- From: "Mikael Abrahamsson" <swmike@swm.pp.se> To: "Mike Hammett via NANOG" <nanog@lists.nanog.org> Cc: "Mike Hammett" <nanog@ics-il.net> Sent: Monday, December 1, 2025 9:04:18 AM Subject: Re: Arista 7280QR-C36 Viability On Mon, 1 Dec 2025, Mike Hammett via NANOG wrote:
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". https://www.arista.com/en/um-eos/eos-ipv4 look for: "ip hardware fib optimize" -- Mikael Abrahamsson email: swmike@swm.pp.se
