Lab 6: Setting up LAB for routing — Dynamic Routing

Chandra Prakash, LPU

b) After assigning IP address, configure the network with RIP v2 Routing Protocol. Ping all

networks from one another. There should be seamless connectivity from every node to

another.

4. Design a topology for 4 network segments connected in given topology through router. Assumethe given IP address and Configure with IGRP Routing Protocol. Ping all networks from one

another. There should be seamless connectivity from every node to another.

5. Create a network having 4 routers, Router A, Router B & Router C and Router D. All router are

connected with serial interfaces and forming a rectangular relationship. Router A has two /19 and

/26 network attached to it. Router B has /28 and /22 & network attached to it. Router C has /17

and /21 and Router D has /24 and /29 network attached to it. Take IP address as 10.2.0.0. and

give IP address to serial interfaces of /30 network. Specify the ranges of IP addresses on each

router for both fast Ethernet and serial interfaces in your notebook. There should be seamless

connectivity from every node to another.a. Use RIP for Routing purpose.

b. Delete the RIP routing from the network and Enable IGRP for the same network. Write

the commands for deleting RIP routing and enabling IGRP






Solution 1.

RIP

Routing Information Protocol (RIP) is a true distance-vector routing protocol.

It sends the complete routing table out to all active interfaces every 30 seconds RIP only uses hop count to determine the best way to a remote network

It has a maximum allowable hop count of 15

AD is 120

Bellman-ford algorithm

Works well in small networks, but it’s inefficient on large networks

RIP version 1 uses only classful routing, which means that all devices in the network must use

the same subnet mask

Command :

R1# config t

R1(config)# )#router rip R1(config)#network Network Address

RIP version 2 does send subnet mask information with the route updates. This is called

classless routing.

Command :

R1# config t

R1(config)# )#router rip

R1(config)#network Network Address

R1(config)#version 2

Cisco RIP commands

• Show ip protocols

• Show ip route

• Show ip route RIP

• Show ip RIP database

• Debug ip RIP

• Debug ip RIP events

• Debug ip routing

IGRP

Some of the IGRP key design characteristics emphasize the following:

It is a distance vector routing protocol.

Routing updates are broadcast every 90 seconds.

IGRP – Hop count 25, default - 100

Bandwidth, load, delay and reliability are used to create a composite metric.

The main difference between RIP and IGRP configuration is that when you configure

IGRP, you supply the autonomous system number. All routers must use the same

number in order to share routing table information.






Command :

R1# config t

R1(config)# )#router igrp 10

R1(config)#network Network Address
