Stage two routers are connected only towards the spine and serve as a transit machine among non-spine locations. Degree 1 routers are fully interior into a non-backbone spot.
ISIS utilizes both equally Level-1 and Level-two Hellos, which means that the two sorts of routers just pointed out can not kind an adjacency. Fortunately for us, There's a middle floor, and that's the extent 1-two router. These routers hook up non-spine locations to backbone places. L1-L2 routers preserve two individual routing tables, 1 for L1 routing and A further for L2 routing.
