Configuring the IS-IS Protocol

Overview/Description
To configure Intermediate System-to-Intermediate System (IS-IS) for a scalable multi-area network

Target Audience
Network engineers responsible for configuring, implementing, troubleshooting, and managing medium-to-large routed networks in an enterprise or service provider environment; network architects responsible for designing networks that support multiple routing protocol types; CCNP, CCDP, and CCIP candidates; CCIE routing and switching candidates

Prerequisites
A good understanding of networking terms, topologies, and the OSI reference model; familiarity with TCP/IP and configuring IP address schemes, including subnetting and variable-length subnet masking (VLSM); experience of operating and configuring Cisco routers for general use and configuring basic routing protocol implementations

Expected Duration
185 Minutes

Objectives:

Configuring the IS-IS Protocol

  • identify the characteristics of IS-IS and the System Discovery Protocol and differentiate between OSI routing levels.
  • differentiate between IS-IS and OSPF routing.
  • recall the features that influence the selection of IS-IS as a preferred routing protocol.
  • identify the characteristics of NSAP and NET addresses.
  • Contrast intra-area and inter-area routing in a CLNS environment and identify uses of link-state and IS-IS packet data units.
  • list the network topologies supported by IS-IS, determine adjacency behavior in a broadcast network, and compare LAN, WAN, and Level 2 adjacencies.
  • outline the purpose of Integrated IS-IS NET addressing for advertising IP networks, recall the path selection process for IS-IS routing, and demonstrate how an IP forwarding database is constructed.
  • recognize the commands used to verify and troubleshoot CLNS IS-IS structures.
  • list the steps for configuring Integrated IS-IS and recognize the commands for optimizing IS-IS operation, verifying IS-IS configuration, and troubleshooting IS-IS operations.
  • configure for IS-IS routing and verify connections using IS-IS routes.
