Cisco Router Network Configuration

This assignment details the configuration of a Cisco 910 Industrial Router to establish a basic client-server network. The configuration includes setting up a DHCP server to assign IP addresses to client PCs, configuring a DNS server for name resolution, and implementing an access control list (ACL) on the router's serial interface to restrict traffic from specific IP addresses.

Executive Summary
This project has two tasks. First one is based on basic network design and configurations. Second
one is based on advanced configuration like DHCP, DNS, HTTP and ACL.
Generally, Client – Server model network organizes network traffic by a client application. Client
can communicate the server such as file transfer, email and web services. One server manages one or
more client systems. This type model can extend more server with more client. It forms a huge network
like Web. This type model network is used to share the hardware devices, applications and etc.
From the first part, I have implemented the basic configuration like hostname, console password
setting and etc. Another one, RIP protocol is implemented between client and server network. It is used
to communicate the remote network.
From the second part, we have implemented the Web Server in server. Server acts as web
server and dns server. I have modified the web page content in web server. If a client request the web
page from web server, web server replied the web content to the requested client. In Client network,
Client Router acts as DHCP server. If any one of the PC requested the IP address from server, Client
DHCP Server pooled the new IP to Client Machine. Lastly, I have implemented the Firewall setting in
Server Router. This is very important for security purpose. It is very helpful to avoid unauthorized access
from remote. I have blocked the communication between PC2 and Server using ACL configurations
From this project, I have learnt the basic configuration of router, Dynamic Routing protocol
implementation, DHCP and DNS Server implementation and advanced firewall configurations

Basic Configuration
To enable privileged mode, use enable command
Router > enable
Router #
To set the hostname, using the following commands
Router # conf t
Router (conf) # hostname Client-Router
To set the Privileged login password,
Client-Router>en
Client-Router#conf t
Client-Router(config)# line console 0
Client-Router(config-line)# password cisco
Client-Router(config-line)# login
Client-Router(config-line)# exit
Client-Router(config)#
To set the IP Address (Client Router)
Client-Router(config)# interface fastEthernet 0/0
Client-Router(config-if)# ip address 192.168.10.1 255.255.255.0
Client-Router(config-if)# no shut
Client-Router(config-if)# exit
Client-Router(config)# interface serial 0/0/0
Client-Router(config-if)# ip address 192.168.11.2 255.255.255.252
Client-Router(config-if)# clock rate 128000
Client-Router(config-if)# no shut
Client-Router(config-if)# exit
Client-Router(config)#
To set the IP Address (Server Router)
Router>en
Router#conf t
Router(config)# hostname Server-Router
Server-Router(config)# interface fastethernet 0/0
Server-Router(config-if)# ip address 10.10.10.1 255.255.255.0
Server-Router(config-if)# no shut
Server-Router(config-if)#exit
Server-Router(config)# interface serial 0/0/0
Server-Router(config-if)# ip address 192.168.11.1 255.255.255.252

Dynamic Routing Configuration
Client-Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Client-Router(config)# router rip
Client-Router(config-router)# version 2
Client-Router(config-router)# network 192.168.10.0
Client-Router(config-router)# network 192.168.11.0
Client-Router(config-router)# exit
Client-Router(config)#

After configuration (Task 1), I have checked the routing table using show ip route command. The
result has shown as

Testing
I checked the connection between client pc and server using ping command. Client has sent the
request signal and then Server responded the client request

Task 2
DHCP Server Configuration
DHCP Server is designed in Client Router. First, I have created the dhcp pool in Client router and
set the network address and default router address. This configuration is used to generate the dynamic
IP address from Client Server Router. This dynamic IP are allocated into Client PC’s.
Client-Router# conf t
Client-Router(config)# ip dhcp pool client-dhcp
Client-Router(dhcp-config)# network 192.168.10.0 255.255.255.0
Client-Router(dhcp-config)# default-router 192.168.10.1
Client-Router(dhcp-config)# dns-server 10.10.10.2
Client-Router(dhcp-config)# exit
Web Server Configuration
In Server, Open the Server Tab->HTTP, click ON radio button (Default is ON Stage). Edit the
index.html page, the HTML code will be,
<html>
<center><font size='+2' color='blue'>I am Mohammed</font></center>
<hr/>

DNS Server Configuration
In Server, Open the Server Tab->DNS, click ON radio button (Default is ON Stage). Enter the Web
Site Name and IP Address of the web server and then Click Add button (First time). If any modification in
DNS enter, just click the enter and modify and click the save button
Firewall Configuration
I have configured the ACL extended in Server Router. This extended ACL set into Server Router
Serial Interface
Server-Router(config)# access-list 101 deny ip host 192.168.10.3 any
Server-Router(config)# access-list 101 permit ip any any
Server-Router(config)#interface serial 0/0/0
Server-Router(config-if)#ip access-group 101 in
Server-Router(config-if)#exit

Testing (Task 2)
DHCP IP Address automatically allocated in Client PC’s. We can easily check the IP address and
Default gateway and DNS server details in PC (PC1->Desktop->IP Configuration)
From PC3, we can see the web page which is requested from mohammed.csu.edu.au. The result is,

From PC2, I have pinged to Server, it is blocked by Server Router because of ACL configuration. All TCP
traffic blocked the IP Address of 192.168.10.2 (PC2). It allows other IP Address. PC1 and PC3 can ping the
Server
