In this article, we will focus on how to configure RIP (Routing Information Protocol) on Cisco Routers. Generally in all network courses, RIP is used to explain routing protocol configuration basically. This is because of its basic configuration.
You can DOWNLOAD the Packet Tracer example with .pkt format HERE.
For our example, we will use the following basic topology:
RIP Example Topology
With this topology, the IP addresses are configured. We will pass the configuration of IP addresses and continue only the routing protocol, RIP configuration.
Before the configuration of RIP, let’s check the routing table of RouterA.
RouterA# show ip route
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area
* - candidate default, U - per-user static route, o - ODR
P - periodic downloaded static route
Gateway of last resort is not set
10.0.0.0/30 is subnetted, 1 subnets
C 10.10.10.0 is directly connected, FastEthernet0/0
184.108.40.206/30 is subnetted, 1 subnets
C 220.127.116.11 is directly connected, FastEthernet0/1
RouterA# show ip protocols
RouterA# show ip int brief
Interface IP-Address OK? Method Status Protocol
FastEthernet0/0 10.10.10.1 YES manual up up
FastEthernet0/1 18.104.22.168 YES manual up up
Vlan1 unassigned YES unset administratively down down
As you can see, there is only directly connected neighbours in the routing table of RouterA. RouterA do not know any other networks, also RouterD. There is no routing protocol configured on RouterA.
Firstly RouterA is configured like below with network commands under rip process.
