Dynamic routing protocols attempt to build a map of the network topology to identify the best routes to reach different destinations. Instead of manually defining static routes, which is not scalable, dynamic routing typically involves defining neighbors and peer routers that share their network topology and routing updates with each other. Protocols like distance vector, link state, and path vector are used by popular routing protocols. FortiGate supports RIP, OSPF, BGP, and IS-IS, which are interoperable with other vendors. When different dynamic routing protocols are used, the administrative distance of each protocol helps the FortiGate decide which route to pick.
