You are going to also turn into familiar with End Systems, referred to in ISIS as an "ES". The End Program is just an finish host.
ISIS and OSPF both use the idea of locations, but ISIS takes a diverse method to this notion. ISIS routers use 3 different sorts of routing levels, according to the alkaline water scam place a router has been placed in. Level 2 routers are connected only to the backbone and serve as a transit device between non-backbone regions. Level 1 routers are entirely internal to a non-backbone region.
ISIS makes use of both Level-1 and Level-two Hellos, which means that the two kinds of routers just mentioned cannot form an adjacency. Luckily for us, there is a middle ground, and that is the Level 1-two router. These routers connect non-backbone places to backbone areas.
