Question:

How can you set up a network where two devices with different IP address ranges can communicate with each other using appropriate network devices and configurations?

To establish communication between two devices with different IP address ranges in the given Cisco Packet Tracer network, follow these implementation steps:

1. Assign IP Addresses to PCs

• PC0 (PC1): Assign an IP address from one network, for example, 192.168.1.1 with subnet mask 255.255.255.0.

• PC1 (PC6): Assign an IP address from a different network, for example, 192.168.2.1 with subnet mask 255.255.255.0.

• PC2 (PC7): Assign another IP address, for example, 192.168.3.1 with subnet mask 255.255.255.0.

Ensure each PC is connected to the switch, as shown in the topology.

2. Configure Router

• Add interfaces for each subnet on the router. For example:

  • Router Interface 1: 192.168.1.254/24

  • Router Interface 2: 192.168.2.254/24

  • Router Interface 3: 192.168.3.254/24

• Set up IP addresses for the router interfaces and connect the router to the switch that connects all PCs.

3. Configure Switch

• Switches don’t require IP addresses for basic connectivity. Just ensure the PCs are connected correctly to the switch, as shown in the diagram.

4. Enable Routing on Router

• Use ip routing command in the router’s global configuration mode to enable routing between the different subnets.

Example:
Router> enable

Router# configure terminal

Router(config)# ip routing

5. Test Connectivity

• Ping Test: From each PC, ping the IP address of another PC in a different subnet to verify the routing configuration.

  • Example: From PC0, ping PC6 (IP: 192.168.2.1).

  • Example: From PC3, ping PC7 (IP: 192.168.3.1).

6. Verify Routing Table

• On the router, use the show ip route command to verify that it has routing entries for all connected networks.

7. Check for Any Errors

• Ensure there are no IP conflicts and verify the devices' connections.

• Troubleshoot if necessary by verifying IP configurations, routing entries, and physical connections.

By following these steps, the devices with different IP address ranges should be able to communicate via the router, achieving inter-network communication.
