IS-IS: Deployment in IP Networks

IS-IS or Intermediate System to Intermediate System protocol is a routing protocol which has long been used by telephone networks and has recently surged in popularity among Internet Service Providers and in other large networks. The IS-IS protocol is used in conjunction with the Border Gateway Protocol (BGP) and offers flexibility in configuration and scalability for large and complex networks. IS-IS is covered in the CCIE (Cisco Certified Internetwork Expert) exam, and those preparing for that challenging exam will be interested in learning more about this protocol. Two Cisco experts here provide a beneficial mix of operational theory of the protocol and many practical examples and case studies. This new guide provides what network professionals need most: highly valuable configuration examples, combined with expert advice on deploying IS-IS in a real network.
