A local Area Network (LAN) is a data communication network connecting various terminals or computers within a building or limited geographical area. In this article, we will know about how to implement a topologies connection between 2 LAN/Topologies in Cisco Packet Tracer.
Steps to Configure and Verify Connection between Two LANs in Cisco Packet Tracer:
Step 1: First, open the Cisco packet tracer desktop and select the devices given below:
| S.NO | Device | Model Name | Qty. |
|---|---|---|---|
| 1. | PC | PC | 8 |
| 2. | Switch | 2496-24TT, PT-Switch | 5 |
| 3. | Router | 2911 | 1 |
IP Addressing Table for PCs of LAN1 and LAN2:
LAN1-
| S.NO | Device | IPv4 Address | Subnet Mask | Default Gateway |
|---|---|---|---|---|
| 1. | PC0 | 13.12.11.1 | 255.0.0.0 | 13.12.11.5 |
| 2. | PC1 | 13.12.11.2 | 255.0.0.0 | 13.12.11.5 |
| 3. | PC2 | 13.12.11.3 | 255.0.0.0 | 13.12.11.5 |
| 4. | PC3 | 13.12.11.4 | 255.0.0.0 | 13.12.11.5 |
LAN2-
| S.NO | Device | IPv4 Address | Subnet Mask | Default Gateway |
|---|---|---|---|---|
| 1. | PC4 | 192.168.1.1 | 255.255.255.0 | 192.168.1.5 |
| 2. | PC5 | 192.168.1.2 | 255.255.255.0 | 192.168.1.5 |
| 3. | PC6 | 192.168.1.3 | 255.255.255.0 | 192.168.1.5 |
| 4. | PC7 | 192.168.1.4 | 255.255.255.0 | 192.168.1.5 |
- Then, create two network topologies (Ring and Bus)as shown below the image.
- Use an Automatic connecting cable to connect the devices with others.
Representation of the topologies should look like the image given below:
Step 2: Configure the PCs (hosts) with IPv4 address, Subnet Mask, and Default gateway according to the IP addressing table above.
- To assign an IP address in PC0, click on PC0.
- Then, go to desktop and IP configuration and there you will find IPv4 configuration.
- ‘Fill IPv4 address, subnet mask, and default gateway to the particular input box.
- Repeat the same procedure with PCs of LAN2 to configure them.
Step 3. Assigning IP address using the ipconfig command.
- We can also assign an IP address with the help of a command.
- Go to the command terminal of the PC0.
- Then, type iPConfig <IPv4 address><subnet mask><default gateway>(if needed)
Example: ipconfig 13.12.11.1 255.255.255.0 13.12.11.5
- Repeat the same procedure with other PCs of Both LANs to configure them thoroughly.
Step 4: Configure router with IP address and Subnet mask.
IP Addressing Table Router:
| Device | Interface | IPv4 Address | Subnet mask |
|---|---|---|---|
| Router0 | FastEthernet0/0 | 13.12.11.5 | 255.255.255.0 |
| FastEthernet0/1 | 192.168.1.5 | 255.255.255.0 |
- To assign an IP address in router0, click on router0.
- Then, go to config and then Interfaces.
- Then, configure the IP address in Fast Ethernet and serial ports according to IP addressing Table.
- Fill IPv4 address and subnet mask.
Step 5: Verifying the network by pinging the IP address of any PC. We will use the ping command to do so.
- First, click on PC0 then Go to the command prompt
- Then type ping <IP address of targeted node>
- As we can see in the below image we are getting replies which means the connection is working properly.
Example : ping 192.168.1.2Simulation Result:
