Setting up LAB for routing(Setting up lab for configuring Dynamic Routing) Routing Protocols(Setting up lab for RIPV1,RIPV2 and IGRP commands) Description of Commands for Configuring Routing Techniques

---------------------------------------------------------------------------------------------------------------------

1. Familiar your-self with the types of Routing protocol –a. Dynamic.

i. Distance Vector ii. Link State

b. RIP – Version1 and Version2 c. Cisco RIP commandsd. IGRP

2. Design a topology for 4 network segments connected in given topology through router. Assume the given IP address and Configure with RIP v1Routing Protocol. Ping all networks from one another. There should be seamless connectivity from every node to another.

3. Consider the given topology for 4 network segments connected through router.

a) Find out the IP Address and SNM of each interface.

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 7 network segments connected in given topology through router. Assume the given IP address and Configure with RIP Routing Protocol. Ping all networks from one another. There should be seamless connectivity from every node to another.

5. Design a topology for 4 network segments connected in given topology through router. Assume the 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.

6. 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 tR1(config)# )#router ripR1(config)#network Network Address

RIP version 2 does send subnet mask information with the route updates. This is called classless routing. Command : R1# config tR1(config)# )#router ripR1(config)#network Network Address R1(config)#version 2

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.
