In the world of IP Routing Protocols much attention is given to RIP, EIGRP, OSPF and BGP. But often, a fifth option, IS-IS, is overlooked and remains a shadowy protocol that intimidates network engineers. This course goes into the details of how IS-IS (Intermediate System to Intermediate System) operates and will remove any trepidation you may feel about it. By drawing frequent comparisons between IS-IS and OSPF, you will learn such topics as; the differences between Level-1 and Level-2 Intermediate Systems, types of IS-IS Link State Packets, how they differ, and what they are used for, LSP Leaking, Pseudonodes, the usage of IS-IS areas, Filtering and Summarization with IS-IS and much, much more. By the time you are finished with this course you will be well-prepared to answer any questions about IS-IS you may encounter on certification exams.
