Intro When you spend a lot of time googling or reading documentation trying to find a solution for some unexpected task and, at the end, it's startworking, you says "WOW! Now then I will use it next time!" But after few months you get the same task and... start from scratch. So I started writing Tips and Tricks for every Network OS (Juniper, Cisco , Huawei etc.) in my notes. After few years I decided to start publish my own collection. Hope it will help me and may be someone else to solve a problem in the future. Some of them are from Day One collection, some from my everyday tasks. Enjoy.
