Comments :

We connect four computer,two switch and one router.Configured all the PC.And to configured the Router we go to the Router CLI and write down the commend on it step by step.And we successfully done it.To check the connection we ping from all PC’’s with both IP address and get reply from it.Finally we send packet to one PC to another and all packets are successfully sends.

Basic Router configuration :

Step-1 : Connecting Router with the PC/Laptop

Connect the console or rollover cable to the router console port,an RJ-45 connector.Next connect the other end of the console or rollover cable to the RJ-45 or RJ-45 to DB-25 adapter depending on the available PC serial port.Finally attached the adepter to a PC serial port,either DB-9 DB-25,depending on the computer.

Fig-10 : Connecting diagram

Step-2 : Start HyperTerminal program :

a.Turn on the computer and router.Then

Fig -11:Turn on Hyper terminal

But in the lab we use Tera Term software to do this.

Step-3 : Name the Hyper Terminal session :

At the connection description popup enter a name in the connection name field and select OK.

Step-4 : Specify the computer connecting interface :

At the “Connect To” popup use the drop down arrow in the Connect using field to select COM-1 and Select OK.

Step-5 : Specify the interface connection properties :

a.At the COM-1 Properties use the drop down arrow to select.

Bit per second :9600

Data bits : 8

Parity : None

Stop bit : 1

Flow control : None

Then select OK

b.The Hyper Terminal session window comes up turn on the router.If the router is already on press the enter key.There should be a respons from the router.If there is then the connection has been successfully completed.

Router Modes :

Router> User mode

Router# Privileged mode (also known as EXEC-level mode)

Router(config)# Global configuration mode

Router(config-if)# Interface mode

Router(config-subif)# Subinterface mode

Router(config-line)# Line mode

Router(config-router)# Router configuration mode

Interface:Supports commands that configure operations on a per-interface basis

Subinterface:Supports commands that configure multiple virtual interfaces on a single physical interface

Controller: Supports commands that configure controllers (for example, E1 and T1 controllers)

Line:Supports commands that configure the operation of a terminal line (for example, the console or the vty ports)

Router:Supports commands that configure an IP routing protocolIf we enter the exit command, the router backs out one level, eventually logging out. In general, we enter the exit command from one of the specific configuration modes to return to global configuration mode. Press Ctrl+Z or enter end to leave configuration mode completely and return to the privileged EXEC mode.

Commands that affect the entire device are called global commands.The hostname and enable password commands are examples of global commands.

Discussion:

In this experiment, at first, Packet Tracer is used to simulate a computer network with four computers, two switches, and one router. A router is a computer networking device that buffers and forwards data packets across an internetwork toward their destinations, through a process known as routing. A router acts as a junction between two or more networks to buffer and transfer data packets among them. A router is different from a switch. A router works on layer 3 of OSI model, while a switch works on layer 2. This experiment gives us a hand on experience of using Packet Tracer for simulating a computer network and pinging from one network’s PC to another network’s PC. While sending PDU from one PC to another, the process became failed sometimes. It happened because the network needs a minimal time to synchronous all the devices. But after trying some more times the PDU could successfully be transferred between the PCs.

Conclusion :

In this lab we learn about the router configuration.Now we are able to setup a router and properly configured it.It was very interesting lab its extend our knowledge about computer networking.
