We run Arista 7280SR's on our edge. I went looking, and as far as I can tell, the TTL is NOT part of the default ECMP algorithm on this platform (Jericho chipset)? We certainly haven't tuned this setting one way or another. I would love for someone more experienced with Arista kit to weigh in on this, since it seems like it may be platform dependent. We do have a support contract so I can reach out to them directly, too.

These commands are the best I could find browsing the Arista docs/blog/forums.

edit: fixed code formatting

edit2: We're on the EOS 4.20.x version train, fwiw

  #show port-channel load-balance jericho fields | grep TTL
