what is difference between routed and routing protocols

A routing protocol sends and receives routing information packets to and from other routers.

A routed protocol can be routed by a router, which means that it can be forwarded from one router to another.

A routed protocol contains the data elements required for a packet to be sent outside of its host netowkr or network segment. In other words, a routed protocol can be routed.

Protocols used to communicate routing information between routers within an autonomous system are Interior Gateway Protocols (IGP), which are routing protocols, but not routed protocols.

Examples of routed protocols are IP and IPX, and examples of routing protocfols are RIP and IGRP.
