Chapter 6 IS-IS Routed Protocol
Well today I spent a lot of time reading and re-reading the IS-IS pages on CLNS NSAP (Network Service Access Points) which is basically the OSI version of an IP address. Since I've been dealing mainly with IPv4 and some IPv6 it's been really hard to grasp the NSAP theory. Nothing like reading the same three pages over and over again until you sorta grasp what they're talking about. I believe that repetition is key to becoming good at anything and this seemed to work pretty well because after that I was able to read the rest of the pages pretty easily. NSAP works very similar to an IP protocol but it reminds me kinda of like NetBIOS for some reason. Tomorrow will be more IS-IS theory, this chapter doesn't have much configuration so may try and lab some other topics in the mean time to keep my CLI skills sharp.
