How to Configure a RiP routing protocol with simple two routers Packet Tracer

How to configure a rip routing protocol with a simple toplogy in GNS 3 to check the connectivity between hosts.



Step 1:Create a topology like this and do basic configurations ip address to the router interfaces ,ip address and default gateway to the host same as in topology.

In Router R1,



R1(config)#interface fastethernet 2/0
R1(config-if)#ip address 10.0.0.1 255.0.0.0
R1(config-if)#no shutdown
R1(config-if)#exit


R1(config)#interface serial 1/0
R1(config-if)#ip address 20.0.0.1 255.0.0.0
R1(config-if)#clock rate 64000
R1(config-if)#encapsulation ppp
R1(config-if)#no shutdown
R1(config-if)#exit


In Router R2,



R2(config)#interface serial 1/0
R2(config-if)#ip address 20.0.0.2 255.0.0.0
R2(config-if)#encapsulation ppp
R2(config-if)#no shutdown
R2(config-if)#exit




R2(config)#interface fastethernet2/0
R2(config-if)#ip address 30.0.0.1 255.0.0.0
R2(config-if)#no shutdown
R2(config-if)#exit

By default routers know directly connected network.



Step 2:Check the routing table of  the router R1 and R2 by giving the command show ip route in privileged mode,


In Router R1,


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

C    10.0.0.0/8 is directly connected, FastEthernet2/0
C    20.0.0.0/8 is directly connected, Serial1/0




In Router R2,




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

C    30.0.0.0/8 is directly connected, FastEthernet2/0
C    20.0.0.0/8 is directly connected, Serial1/0

Step 3:Now,Run Rip protocols on R1 and R2 .What rip will do is, it will create a routing update by adding directly connected networks information and it will send to neighbor routers

Just add directly connected networks

In Router R1,

R1(config)#router rip

R1(config-router)#network 10.0.0.0

R1(config-router)#network 20.0.0.0

R1(config-router)#exit

In Router R2,

R2(config)#router rip

R2(config-router)#network 20.0.0.0

R2(config-router)#network 30.0.0.0

R2(config-router)#exit

Now routers learns network information automatically through routing updates

Step 4:Now give show ip route command in R1 and R2 and check the routing table

In Router R1,

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

C    10.0.0.0/8 is directly connected, FastEthernet0/0

C    20.0.0.0/8 is directly connected, Serial2/0

R    30.0.0.0/8 [120/1] via 20.0.0.2, 00:00:28, Serial2/0

R1#

Here,network 30.0.0.0 learned by the router R1 via Serial 2/0 by routing update from R2,that will be reachable via 20.0.0.2(next hop).

[120/1]-120 Administrative distance of Rip,1-Reachable on one hop.

In Router R2,

R2#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

R    10.0.0.0/8 [120/1] via 20.0.0.1, 00:00:16, Serial2/0

C    20.0.0.0/8 is directly connected, Serial2/0

C    30.0.0.0/8 is directly connected, FastEthernet0/0

Here,network 30.0.0.0 learned by the router R2 via Serial 2/0 by routing update from R1,that will be reachable via 20.0.0.1(next hop).

Step 5:Now ping from the Host 10.0.0.10 to Host 30.0.0.10 by giving command 

ping 30.0.0.10 you will get,

Rip Timers:

Update Interval-30

Invalid Interval -180

Hold Down Interval -180

Flush After-240

Administrative Distance-120
