Basic Router Configuration using Cisco
Objective
The objective of this lab is to configure a basic
router setup using Cisco Packet Tracer. The setup involves configuring the IP
addresses for a router and two PCs as shown in the topology diagram.
Topology
Diagram
The network topology consists of one router and two
PCs connected through FastEthernet interfaces. The IP addresses and subnet
masks for each device are as follows:
- Router Interface Fa0/0:
- IP Address:
192.168.20.1
- Subnet Mask:
255.255.255.224
- Router Interface Fa1/0:
- IP Address:
192.168.10.1
- Subnet Mask:
255.255.255.224
- PC1:
- IP Address:
192.168.20.2
- Subnet Mask:
255.255.255.224
- PC2:
- IP Address:
192.168.10.2
- Subnet Mask:
255.255.255.224
Equipment
- Cisco Packet Tracer software
- 1 Cisco Router
- 2 PCs
- 2 Ethernet cables
Steps and Configuration
Step 1: Setting up the Network Topology
1. Open Cisco Packet Tracer.
2. Place the devices:
- Drag and
drop one router and two PCs onto the workspace.
3. Connect the devices:
- Connect PC1
to the router’s Fa0/0 interface using an Ethernet cable.
- Connect PC2
to the router’s Fa1/0 interface using an Ethernet cable.
Step 2: Configuring the Router Interfaces
1. Select the router and enter the CLI:
- Click on
the router and then click on the `CLI` tab.
2. Enter global configuration mode:
```
Router>
enable
Router#
configure terminal
```
3. Configure the Fa0/0 interface:
```
Router(config)# interface FastEthernet0/0
Router(config-if)# ip address 192.168.20.1 255.255.255.224
Router(config-if)# no shutdown
Router(config-if)# exit
```
4. Configure the Fa1/0 interface:
```
Router(config)# interface FastEthernet1/0
Router(config-if)# ip address 192.168.10.1 255.255.255.224
Router(config-if)# no shutdown
Router(config-if)# exit
```
5. Verify the interfaces are up:
```
Router# show
ip interface brief
```
Step 3:
Configuring the PCs
1. PC1 Configuration:
- Click on
PC1.
- Go to the
`Desktop` tab and open the `IP Configuration`.
- Set the IP
address to 192.168.20.2.
- Set the
subnet mask to 255.255.255.224.
- Set the
default gateway to 192.168.20.1.
2. PC2 Configuration:
- Click on
PC2.
- Go to the
`Desktop` tab and open the `IP Configuration`.
- Set the IP
address to 192.168.10.2.
- Set the
subnet mask to 255.255.255.224.
- Set the
default gateway to 192.168.10.1.
Step 4: Testing
Connectivity
1. Ping from PC1 to the router’s Fa0/0 interface:
- Open the
`Command Prompt` from the `Desktop` tab on PC1.
- Enter the
command:
```
ping
192.168.20.1
```
- Verify that
the ping is successful.
2. Ping from PC2 to the router’s Fa1/0 interface:
- Open the
`Command Prompt` from the `Desktop` tab on PC2.
- Enter the
command:
```
ping
192.168.10.1
```
- Verify that
the ping is successful.
3. Ping from PC1 to PC2:
- Open the
`Command Prompt` from the `Desktop` tab on PC1.
- Enter the
command:
```
ping
192.168.10.2
```
- Verify that
the ping is successful.
Results
After completing the configuration steps, both PCs
should be able to communicate with each other through the router. Successful
pings between the PCs and from the PCs to the router interfaces indicate that
the network is correctly configured.
Conclusion
This lab demonstrated the basic steps to configure a
router and connect two PCs using Cisco Packet Tracer. The essential
configurations included setting up IP addresses and subnet masks on the router
interfaces and the PCs. Testing the connectivity confirmed that the setup was
successful and the devices were able to communicate with each other.
By following these steps, you can set up a basic
network topology and understand the foundational aspects of router
configuration.
