How to configure RIP in Cisco Routers

RIP (Routing Information Protocol) is the oldest distance vector routing protocol. The maximum number of hop count is 15 and the hop count number 16 is defined as infinite distance. The converged time is slow if compared with other routing protocols such as EIGRP, OSPF and IS-IS. There are two versions in RIP: version 1 and version 2.

RIP V1

RIP v1 uses FLSM (fixed length subnet masking) and does not support VLSM(variable length subnet masking). Using FLSM causes IP wastes.

FLSM Examples,

192.168.1.0 /24
192.168.2.0 /24

RIP V2 

RIP V2 supports VLSM (variable length subnet masking). If there are different amount of hosts in an organization, we should use RIP v2.

For example,

HR Department : 20 hosts
Engineering Department: 50 hosts
IT department: 10 hosts
Sales department: 30 hosts


The following is the sample configuration of RIP in Cisco Routers.


Router 1

Activate Connection to Router 2

en
config t
int s0/0/0
ip address 200.100.10.1 255.255.255.252
clock rate 64000
no shut


Activate Connection to Switch 1

int g0/0
ip address 192.168.1.1 255.255.255.0
no shut
 
Configure RIP V1/V2

router rip
version 2
network 192.168.1.0
network 200.100.10.0
end

Save the Configuration

copy run start

Switch 1

Activate Connection to Router 1

en
config t
int f0/1
no shut

Activate Connection to PC5

int f0/2
no shut

Activate Connection to PC6

int f0/3
no shut
end

Save the Configuration

copy run start

Router 2

Activate Connection to Router 1

en
config t
int s0/0/0
ip address 200.100.10.2 255.255.255.252
clock rate 64000
no shut


Activate Connection to Switch 2
 
int g0/0
ip address 192.168.2.1 255.255.255.0
no shut
 
Configure RIP V1/V2

router rip
version 2
network 192.168.2.0
network 200.100.10.0
end

Save the Configuration

copy run start

Switch 2

Activate Connection to Router 2 

en
config t
int f0/1
no shut

Activate Connection to PC7

int f0/2
no shut

Activate Connection to PC8

int f0/3
no shut
end

Save the Configuration

copy run start
