What is ISIS?

IS-IS (Intermediate System to Intermediate System) is a routing protocol used to efficiently route data packets within a network. It's commonly used by Internet Service Providers (ISPs) and large enterprise networks. IS-IS is a link-state routing protocol, meaning that each router maintains a map of the network's topology. It's known for its scalability and stability in large networks, and is considered an alternative to OSPF.
