Imagine you need a data center WAN edge router with multiple 10GE uplinks. You’d probably go for an ASR or a MX-series router, right? How about using a 2 Tbps ToR switch and an SDN solution to make it work with full Internet routing table?
David Barroso from Spotify decided to do exactly that. He figured out he needs only a small fraction of the functionality of a reassuringly expensive WAN edge router. Then he listened to the NANOG presentation by Elisa Jasinska, said “that’s exactly how I could figure out what I really need in my forwarding tables”, and implemented a good-enough solution that solves his WAN connectivity challenges with an Arista ToR switch.
