Learning How YANG, RESTCONF, Docker, and Golang can be useful for a Network Engineer 07/14/2018 While it sounds like buzzword soup, there is a way to align the stars and make these tools useful for a myriad of situations. In this post, I'll go over a basic example of how to develop a bare-bones web app in Go to interface with a Cisco IOS-XE Router using RESTCONF as our entry point and YANG modeling to normalize the data. Finally, when it's all working we'll 'Dockerize' the app for easy distribution. Goal A lot to cover, so

Learning IPsec - Transport vs Tunnel Mode 07/09/2018 IPsec: Tunnel Mode VS Transport Mode Here we'll go over the difference between Tunnel and Transport mode IPsec configurations and when to use each one respectively. All configurations and packet captures can be found on GitHub, here In a quick sentence, transport mode IPsec only encapsulates the inner content excluding the original IP header, while tunnel mode encapsulates the entire inner content, including the IP header. In each case, the content needs to traverse a network, therefore the
