I have been over the automatic creation of the VXLAN topology in the previous post. However, this stopped at the creation of the topology only. If in the future I wanted to add a new spine or leaf switch, this could be done, but the other switches wouldn’t be aware as they would also need […]

This is going to follow on from the previous post to get a basic three switch topology up and running with VXLAN. This time however, instead of doing more VXLAN I will concentrate on a way to automate the adding of spine and leaf switches to the fabric.The purpose of this automation piece is to

This post is a follow-up to the post I created that gives a basic multi threaded example. There isn’t any context and when I came back to the code I found it difficult to translate into one of my functions. In this example, I will take a function of my F5 Flask Dashboard that has

When I was creating the page in my Scrapli and Flask Project for Multicast details. I had a requirement to split a string on multiple delimiters. As always Stack Overflow came to aid me. The “show ip mroute” plain text output from the Nexus switch uses multiple delimiters for new lines, three specifically: “\n, \n\n,

I used Genie and TextFSM to parse Cisco output in order to get specific details.TextFSM in ProjectGenie in ProjectHere I want to take a closer look at creating a TextFSM template. As I could not easily find a TextFSM template for the Nexus command “show ip mroute” I

I have added the ability to create a base device template for Cisco IOS, Nexus and IOS-XE.The idea of this is to create a quick way to get a basic configuration to SSH on to the device. For switches, the options for configuration can become quite complex as you can have either a VLAN or
