Cisco Networking Lab Assignment

This Cisco networking lab assignment guides students through configuring various network services on a router. Tasks include setting up a DHCP server to assign IP addresses automatically, configuring a web server to host a webpage, establishing a DNS server for URL resolution, and implementing a firewall to control traffic flow between devices. The lab utilizes command-line interfaces and provides step-by-step instructions with screenshots demonstrating the configuration process.

Figure 1: PC0 Configuration
The above screenshot demonstrates the configuration of the Pc0 used in the client end of
the network diagram. The gateway address 192.168.1.1 is used which is the IP address of the
interface of router 0.

Router 2
Figure 8: Configuration of the Router 2 interface
The above screenshot defines the static IP address used for the configuration of the serial
interface S0/3/0 of Router 2. It is used for communicating with the router 1 and the PC connected
with the Fast Ethernet of the router 1.

Figure 9: Configuration of the Router 2 interface
The above screenshot defines the static IP address used for the configuration of the fast
Ethernet interface Fa 0/0 of Router 2. It is used as the default gateway address for the servers
installed on the other end of the router for communicating with the other device installed in the
network.
5. Configuration of the routing on the routers
Router 1 Configuration
Router>enable
Router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#interface FastEthernet0/0

11
INTERNETWORKING WITH TCP/IP
Router(config-if)#ip address 192.168.1.1 255.255.255.0
Router(config-if)#
Router(config-if)#exit
Router(config)#interface Serial0/3/0
Router(config-if)#ip address 192.168.2.1 255.255.255.252
Router(config-if)#exit
Router(config)#ip route 192.168.3.0 255.255.255.0 192.168.2.2
Router(config)#
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to down
Router 2 Configuration
Router>enable
Router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#interface Serial0/3/0
Router(config-if)#ip address 192.168.2.2 255.255.255.252

Figure 16: Configuration of the WEB server

18
INTERNETWORKING WITH TCP/IP
The above screenshot shows the configuration of the WEB server where the HTTP and
the HTTPS services are turned on. From the WEB server the Web page can be hosted for serving
the needs of the client end PC connected in the network. The URL to reach the webserver is used
as the www.YOUR NAME.csu.edu.au.
3. DNS Configuration
Figure 17: Testing of the DNS server
The DNS server is configured by adding an IP address with the URL used for accessing
the webserver and the above screen shot shows the working of the DNS server as the URL is
used for accessing the Web page hosted on the Web server.

19
INTERNETWORKING WITH TCP/IP
Figure 17: Testing of the DNS server
The above screenshot is used for the testing of the configuration of the DNS server using
the IP address of the Web server. The DNS server is configured for the resolving of the URL to
the IP address of thee WEB server.
4. Firewall Configuration
The firewall configuration is used for blocking the PC 1 to communicate with the Web
server and for this the access control list is configured. The configuration command used for
blocking the PC are given below:
Router(config)#access-list 101 deny tcp host 192.168.1.2 host 192.168.3.6 eq 80
Router(config)#access-list 101 permit ip any any

20
INTERNETWORKING WITH TCP/IP
Router(config)#int fa 0/0
Router(config-if)#ip access-group 101 in
Router(config-if)#exit
Figure 18: Testing of the firewall configuration
The above screenshot is used for testing the firewall configuration, the browser of the PC
1 is opened and the URL or the IP address is typed for testing the configuration of the traffic
filtering on the router for blocking thee TCP traffic between the client PC 1 and the web server.
