Sorry we messed up (denog17)

How we route-leaked everything to everyone due to a fun Arista bug. A post-mortem kind of story about us changing Arista RCF function names, resulting in a global route leak. The talk includes the history of why we intended to make a change, how we rollout configurations, why it resulted in an unexpected behavior and how it was fixed.
