A routed protocol is a protocol by which data can be routed. Routed protocol are IP, AppleTalk, and IPX. In this kind of 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, and workstations to. 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. There are three classes of routing protocols- 1)distance vector, 2)link state,3)hybrid
OSPF is one of two link state protocols, the other one is IS-IS. EIGRP is the only hybrid protocol but in normal literature you will see that EIGRP is distance vector routing protocol.
understand people like data. bus like routed protocol & signals on road like routing protocol.
IP is a vast protocol. IP has many features but yep we can say it holds data.
jsut like we need food on plate to eat. routed protocols also works for a specific protocols. they understand only IP or IPX or appletalk. so they data in IP packet form to get routed.
Dear all ,
Thanks for the replies but I have some questions about this,
Is it true that "routing" and "routed protocols" both are part of "network protocols"?
Also can we say that "routing protocols" not only update the routing tables of the routers, but also forwards the packets based on the best available route or path?
1. "Is it true that "routing" and "routed protocols" both are part of "network protocols"?"
Yes that seems to be correct.
2." Also can we say that "routing protocols" not only update the routing tables of the routers"
Yes that seems to be correct too.
3. ", but also forwards the packets based on the best available route or path?"
No, that's not the case. The forwarding decision will depend on the logic configured within the router. The routing table informs the router , that those are the best paths available. By default, the router consults those tables, and basis its forwarding decisions on those tables.
However, the router can be programmed to ignore those entries and make independent decisions about forwarding paths.
