IS-IS

Intermediate System to Intermediate System (IS-IS) is an Interior Gateway Protocol (IGP) and runs at the link layer. IS-IS features rapid aggregation and a hierarchical structure. IS-IS is widely used on large-scale carrier networks.

Overview of IS-IS: Intermediate System to Intermediate System (IS-IS) is a link status protocol that uses the shortest path first (SPF) algorithm to calculate routes.

Understanding IS-IS: This section describes ISIS principles.

Configuring IS-IS: By building IS-IS networks, you can enable IS-IS to discover and calculate routes in ASs.

Maintaining IS-IS: Maintaining IS-IS involves resetting IS-IS and clearing IS-IS statistics.

Configuration Examples for IS-IS: This section provides several configuration examples of IS-IS. The configuration examples explain networking requirements, and configuration roadmap.
