Configuring RIP

RIP is one of the oldest routing protocols, but it is still used in small networks. In our days there are two versions of this protocol. The number of steps between routes from one network to another is the metric of this protocol(the maximum number is 15 for default). If the number is more that 15, the router will not deliver the package.

By default the routes are updated every 30 seconds. Updating of routing table are sent only to neighbour routers. Protocol RIP version 1 supports only network with standout masks, network classes A, B, C. RIP version 2 supports not only standard masks. Also authentication is supported by RIP version 2.

To enter in configuring RIP, you should enter "router rip" command. Then using command "version 1|2" you can choose the version of RIP.I suggest you to use RIP version 2, because it also includes RIP version 1 options. Then using "network" command you should provide the network, that connected to this router directly.

Main commands:
router rip - enter in configuration rip mode;
version(1|2) - protocol version;
network (ip address) - network address;
show ip route - show route table;
debug ip rip - enable debug mode for RIP.

Example of configuration:
Router(config)#router rip
Router(config-router)#network 192.168.3.0
Router(config-router)#network 192.168.5.0
Router(config-router)#network 192.168.1.0
