Configuring a Router in Cisco Packet Tracer (Quick method)

Basic Router Configuration

Objectives:

This Lab includes procedures for configuring the basic parameters of your Cisco router, including global parameter settings, interfaces, and command-line access.

Overview:

 Router is a device that forwards data packets along networks. A router is connected to at least two networks, commonly two LANs or WANs or a LAN and its ISP's network. Routers are located at gateways, the places where two or more networks connect, and are the critical device that keeps data flowing between networks and keeps the networks connected to the Internet.

Lab Instructions:
 Viewing Basic Router Information
Step#1:
Open the Packet Tracer and Press Control+Alt+R and then select a Router; In this case we have selected 1841 Cisco Router.
Step#2:
Click on the Router Icon and then select the CLI for configuring it. The following interface will appear,
Type no and then press enter. Again press Enter and now you are in user mode, you will see that a prompt appears here.

Configure Global Parameters
Step#1:
Open the Packet Tracer Select the Same Router and get into user mode.
Step#1:
When the User mode prompt appears perform these steps to configure selected global parameters for your router:
Set a console password to Cisco
Router(config)#line con 0 Router(config-line)#login Router(config-line)#password cisco
Router (config)#line con 0
Router (config-line)#logging synchronous

Turns on synchronous logging. Information items sent to console will not interrupt the command you are typing. The command will be moved to a new line

Router(config-line)#exec-timeout 0 0
Sets time limit when console automatically logs off. Set to 0 0 (minutes seconds) means console never logs off.
Connecting two different Networks via a Router

Step#1
Router(config)#interface fastEthernet 0/0
Router(config-if)#ip address 192.168.1.100 255.255.255.0
Router(config-if)#no shut down
%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up
Router(config)#interface fastEthernet 0/1
Router(config-if)#ip address 192.168.2.100 255.255.255.0
Router(config-if)#no shut down
%LINK-5-CHANGED: Interface FastEthernet0/1, changed state to up
Step#2
Assign an ip address to pc0 in the same subnet given to the interface of the router.
And ping the ip address of the router interface for checking connectivity.
For remote login:
Type the following configuration commands on the router:
Router(config)#line vty 0 4
Router(config-line)#password cisco
Router(config-line)#login
