Routing protocols are the rules that devices must follow in order to share route information over a network. Everyone needs to share directions so that everything goes where it needs to go. There are two main types of routing protocols: distance-vector and link-state. <\/p>\n

The IS-IS routing protocol comes in two key types: Level 1 and Level 2. Each one has its own role and works in different parts of the network. Here\u2019s what they are:<\/p>\n
