IS-IS (IS-IS) Hard Skill
IS-IS (Intermediate System to Intermediate System) is a routing protocol designed to move information efficiently within a computer network by determining the best path for data through a packet-switched network. It is widely used in large ISP and enterprise networks for its scalability and fast convergence.
