   1. Physical layer. v. t. e. Intermediate System to Intermediate System ( IS-IS, also written ISIS) is a routing protocol designed to move information efficiently within a computer network, a group of physically connected computers or similar devices. It accomplishes this by determining the best route for data through a packet switching network.

   Apr 27, 2024 · The process of ISIS can be broken down into three stages: 1. Neighbor Discovery. In this stage, each router discovers its neighboring routers and forms adjacencies with them. This is done by sending out ISIS hello packets, which contain the router's ID, priority, and hold time. 2. Link-State Advertisement (LSA)
