IS-IS Course by Russ White

Learn Intermediate System to Intermediate System (IS-IS) with network expert Russ White in a self-paced video course focused on the core concepts and design principles behind the IS-IS routing protocol used in service provider and large-scale enterprise networks. You’ll compare the IS-IS protocol with OSPF, see where each fits, and build a clear mental model you can apply in real deployments.

Core Topics Covered

• IS-IS basics and how it differs from OSPF
• The flooding process, Link State Packet (LSP) creation, and LSP management
• Splitting flooding domains, aggregation and summarization, and routing between Level 1 and Level 2 domains
• Neighborship formation in IS-IS, including neighbor discovery, timers, and multiaccess links

How You’ll Learn

Short, focused lessons walk through the IS-IS Basic Flooding Process, controlling flooding domains, and stable neighbor formation so you can apply IS-IS confidently in large networks or while preparing for advanced design certifications such as CCDE.
