Routed versus routing protocols

Two categories of protocol exist at the network layer: routed and routing. A routed protocol is a Network Layer protocol that is used to move traffic between networks. Routed protocols allow a host on one network to communicate with a host on another, with routers forwarding traffic between the source and destination networks. IP, IPX, and AppleTalk are all examples of routed protocols. Routing protocols let routers route routed protocols after a path has been determined. RIP, IGRP, EIGRP, OSPF, IS-IS, BGP are all examples of routing protocols.
