Distance Vector | Dynamic Routing | RIPv2

CISCO as The algorithm creator of RIPv1 known that The service of RIPv1 has some weakness, example : we can't use class less in configuration RIPv1. SO The RIPv1 need to development and overcome it's problems. That development is RIP version 2. RIPv2 was designed for class less, and it is better than RIPv1. To configure RIPv2, you must know how to configure the RIPv1, RIPv2 configuration is different with RIPv1.


There are some additional commands for use RIPv2, so it can use less class:

1. version 2: to select RIPv2


2. no auto-summary: to overcome the confusion network


3. passive-interface: to affirm that each IP interface that is used is different.

Our Scenario:
We need 3 routers and 3 Clients

• PC Client 1 connected to fa0/0 using IP network 10.10.10.0/24


• PC Client 2 connected to fa0/0 using IP network 10.30.10.0/24


• PC Client 3 connected to fa0/0 using IP network 10.50.10.0/24


• Serial2/0 of Router 1 connected to Serial3/0 of Router 2 using IP network 10.20.10.0/30


• Serial2/0 of Router 2 connected to Serial3/0 of Router 3 using IP network 10.40.10.0/30

Configuration on PC Client

PC1	PC2	PC3
IP address : 10.10.10.2 Netmask : 255.255.255.0 Gateway : 10.10.10.1	IP address : 10.30.10.2 Netmask : 255.255.255.0 Gateway : 10.30.10.1	IP address : 10.50.10.2 Netmask : 255.255.255.0 Gateway : 10.50.10.1

Configuration on Router

Router 1

Router>enable Router#configure terminal Router(config)#hostname R1 R1(config)#interface fa0/0 R1(config-if)#ip address 10.10.10.1 255.255.255.0 R1(config-if)#no shutdown R1(config-if)#exit R1(config)#interface s2/0 R1(config-if)#ip address 10.20.10.1 255.255.255.252 R1(config-if)#clock rate 64000 R1(config-if)#no shutdown R1(config-if)#exit Register network on Router 1 R1(config)#router rip R1(config-router)#version 2 R1(config-router)#no auto-summary R1(config-router)#passive-interface fa0/0 R1(config-router)#network 10.10.10.0 R1(config-router)#network 10.20.10.0 R1(config-router)#end

Router 2

Router>enable Router#hostname R2 Router#configure terminal Router(config)#hostname R2 R2(config)#interface fa0/0 R2(config-if)#ip address 10.30.10.1 255.255.255.252 R2(config-if)#no shutdown R2(config-if)#exit R2(config)#interface s3/0 R2(config-if)#ip address 10.20.10.2 255.255.255.252 R2(config-if)#no shutdown R2(config-if)# R2(config-if)#exit R2(config)#interface s2/0 R2(config-if)#ip address 10.40.10.1 255.255.255.252 R2(config-if)#clock rate 64000 R2(config-if)#no shutdown R2(config-if)#exit Register network on Router 2 R2(config)#router rip R2(config-router)#version 2 R2(config-router)#passive-interface fa0/0 R2(config-router)#network 10.30.10.0 R2(config-router)#network 10.20.10.0 R2(config-router)#network 10.40.10.0 R2(config-router)#end

Router 3

Router>enable Router#configure terminal Router(config)#hostname R3 R3(config)#interface fa0/0 R3(config-if)#ip address 10.50.10.1 255.255.255.0 R3(config-if)#no shutdown R3(config-if)#exit R3(config)#interface s3/0 R3(config-if)#ip address 10.40.10.2 255.255.255.252 R3(config-if)#no shutdown R3(config-if)#exit Register network on Router R3(config)#router rip R3(config-router)#version 2 R3(config-router)#passive-interface fa0/0 R3(config-router)#network 10.50.10.0 R3(config-router)#network 10.40.10.0 R3(config-router)#end

To show configuration your RIPv2, please do this command:
R1#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

10.0.0.0/8 is variably subnetted, 5 subnets, 2 masks
C 10.10.10.0/24 is directly connected, FastEthernet0/0
C 10.20.10.0/30 is directly connected, Serial2/0
R 10.30.10.0/30 [120/1] via 10.20.10.2, 00:00:12, Serial2/0
R 10.40.10.0/30 [120/1] via 10.20.10.2, 00:00:12, Serial2/0
R 10.50.10.0/24 [120/2] via 10.20.10.2, 00:00:12, Serial2/0

If you do step by step about configuration RIPv2, you have gotten a RIPv2 with 3 router. Please improve your skill using more than 3 router, We believe you can do it. Trust yourself!!
