RIP (Routing Information Protocol) is the routing protocol and one format of Distance Vector by the nature of RIP that it will sending all routing table data by itself go out to neighbor router in every 30 second and work on UDP and on port 520 numbers, that's why make RIP work slow and consume the very resource of router more when compare with other routing protocol such as OSPF Routing Protocol and EIGRP Routing Protocol these sending out for updated routing table only.

For the factor of choosing best route path on RIP, it will choose the routing path route that have least Hop Count, that is one factor for choosing by the topmost space or Maximum Hop Count of RIP that 15 router or 15 hop count only if have more 15 will can not seek the route path or inaccessible, which RIP that will work well with the network that have small-sized and it will can not work efficiently in large-sized network because of the limitation about Hop Count and the lateness in routing table update at must exchange both of the table and must wait for 30 seconds before change the routing table.

This below is the step for how to configure RIP to your router.

- Login to router Global Configuration Mode with this command

Router#enable

- Change to RIP Routing Configuration with command

Router(config)#router rip

- Change for run to RIP version 2

Router(config-router)#version 2

- Step for setting up an your network address of your router interfaces that your router interface has connected to. For example we'll setting for two network address as below

Router(config-router)#network 192.168.1.0

Router(config-router)#network 192.168.50.0

- If in Network you has Discontingous Network Address or have don't conform address if you set for router use Auto-Route Summarization feature sometimes may have the error in something route which the command will come use to stop doing Auto-Summarization this for example.

Router(config)#router rip

Router(config-router)#no auto-summary

- If in your router connected goes out to WAN Link far exceed location more than limits that you wants true such as if you have network address 172.16.1.0, 172.16.2.0 and 172.16.3.0 and already set for both three interfaces of router but, while you set in router rip you will necessary must set in Classful Network Address like 172.16.0.0 which in this example if 172.16.3.0 networks are you set it run on other routing protocol such as OSPF or EIGRP and you don't want a result that routing rip go to disturb WAN Link traffic go to interface at you don't want you can stop traffic that be from RIP sending to that interfaces with this command.

Router(config)#router rip

Router(config-router)#passive-interface

- If you want to send routing update cross interface at have doing Passive Interface go to destination interface at run RIP once more, This interface may be interface behind interface that do Passive Interface make RIP broadcase traffic usually don't arrive come to, you can make specify RIP traffic cross to interface of Passive Interface come to the uprightly destination with the command as follows.

Router(config)#router rip

Router(config-router)#neighbor

RIP Troubleshooting and Debug Command

show ip route - Use for show routing table

show protocols ? Use for show Routed Protocol such as IP, IPX and view for status of that routed protocol interface

show ip protocols ? Use for show routing protocol status and RIP timing update and Administrative Distance (AD)

debug ip rip ? Use for view step on sending network address on RIP and view for RIP changing topology

undebug all ? Disable for Debug Process

This is the basic information and how to setting up RIP Routing Protocol in to your network it is simple and fast for setting up on small-sized network and use on classful ip address to apply on, but for the large network we'll apply for the classless routing protocol such as OSPF or EIGRP that is these routing protocol it have a very performance and stable for the lage-sized network or hard working network, but you can do with the high knowledge or have more skills on networking system and routing protocol.
