Most of the networking professionals ignore about this, but it’s a must ask question in interviews at CCNA level.
Let’s know about it in short.
A routed protocol is a protocol by which data can be routed. Routed protocol are IP, AppleTalk, and IPX.
In Routed Protocols we require an addressing scheme and subnetting. Addressing scheme will be used to determine the network to which a host belongs and to identifying that host on that particular network. All hosts on an internetwork are using the services of a routed protocol. That means routers, servers, but workstations too. The only two routed protocols that are in use today are IP and IPX but IPX is dropped from Cisco in exams and is not in use much these days. If you are studying routed protocols the best advice is to focus on IP routed protocol.
A routing protocol is different and is only used between routers. It makes possible for routers to build and maintain routing tables.
