||CleanOpenFabric with Russ White on Software Gone Wild||Continuing the series of data center routing protocol podcasts, we sat down with Russ White (of the CCDE fame), author of another proposal: OpenFabric. As always, we started with the “what’s wrong with what we have right now, like using BGP a||4/19/2018||Free||View in iTunes|
||CleanData Center Routing with RIFT on Software Gone Wild||Years ago Petr Lapukhov decided that it’s a waste of time to try to make OSPF or IS-IS work in large-scale data center leaf-and-spine fabrics and figured out how to use BGP as a better IGP. In the meantime, old-time routing gurus started designing||3/30/2018||Free||View in iTunes|
||CleanLinux Interfaces on Software Gone Wild||Continuing the Linux networking discussion we had in Episode 86, we focused on Linux interfaces in Episode 87 of Software Gone Wild with Roopa Prabhu and David Ahern.

||CleanStart Using OpenConfig with NAPALM on Software Gone Wild||OpenConfig sounds like a great idea, but unfortunately only a few vendors support it, and it doesn’t run on all their platforms, and you need the latest-and-greatest software release.
