Document The First Time, Every Time
Imagine you’re deep into a massive issue. You’ve been troubleshooting for hours trying to figure out why something isn’t working. You’ve pulled in resources to help and you’re on the line with the TAC to try and get a resolution. You know this has to be related to something recent because you just got notified about it yesterday. You’re working through logs and configuration setting trying to gain insights into what went wrong. That’s when the TAC engineer hits you with with an armor-piecing question:
When did this start happening?
Now you’re sunk. When did you first start seeing it? Was it happening before and no one noticed? Did a tree fall in the forest and no one was around to hear the sound? What is the meaning of life now?
It’s not too hard to imagine the above scenario because we’ve found ourselves in it more times than we can count. We’ve started working on a problem and traced it back to a root cause only to find out that the actual inciting incident goes back even further than that. Maybe the symptoms just took a while to show up. Perhaps someone unknowingly “fixed” the issue with a Continue reading
Heavy Networking 580: Multivendor EVPN? Nope
Today's Heavy Networking is a nerdy excursion into EVPN VXLAN, including how it works, why you might want it, and why multivendor interoperability is so difficult with this standard. Guest Tony Bourke and host Ethan Banks also explore hardware challenges, automation strategies, EVPN flooding mechanisms, BGP multi-homing, and more.Heavy Networking 580: Multivendor EVPN? Nope

Dennis Jennings and the History of NSFNET
The NSFNET followed the CSNET, connecting the campuses of several colleges and supercomputing systems with a 56K core in 1986. The NSFNET was the first large-scale implementation of Internet technologies in a complex environment of many independently operated networks, and forced the Internet community to iron out technical issues arising from the rapidly increasing number of computers and address many practical details of operations, management and conformance. The NSF eventually became the “seed” of the commercialized core of the Internet, playing an outsized role in the current design of routing, transport, and other Internet technologies.
In this episode of the History of Networking, Dennis Jennings joins Donald Sharp and Russ White to discuss the origins and operation of the NSFNET.
