In Part 2 of my ongoing series on IS-IS, we take a look at some real nice packet captures. You’re going to learn how hello and LSP messages work, how adjacencies work, and we even explore our feelings together, so that we can finally find inner-peace with ourselves. Great!!!
Here’s the first post in my five-part guide to IS-IS. Wow, what a Christmas treat! In this first post we compare IS-IS to OSPF; we’ll talk about Level 1 and Level 2; we’ll explain the unique addressing system; we’ll look at a basic config, and we’ll talk about why Googling for IS-IS is very different from Googling for ISIS.
