The upcoming release of Suzieq(github.com/netenglabs/suz…) has a ton of new features. A favorite of mine is to address a common problem of network operators. Finding the switch where a MAC or IP address is attached. Sample screenshot:

I've been doing a lot of Go + rtnetlink plumbing recently and I think it's time to add nexthops API support to github.com/jsimonetti/rtn…! Thanks @dsahern for your work on this, and for the very informative presentation: linuxplumbersconf.org/event/4/contri… #golang #linux #networking

Listened to the latest Kernel of Truth podcast from @CumulusNetworks while working out. Good updates on FRR from @menotyousharp. Loved the progress on nexthop groups. Look forward to updates on the route install times.
