- Create and connect multiple subnets
- Configure router interfaces for different networks
- Set IP addresses and subnet masks
- Enable communication between networks using routing
- Test connectivity between devices across different subnets
Ideal for networking students and beginners who want to understand inter-network communication and basic routing concepts in simulated environments.
- Cisco Packet Tracer – for network design and simulation
- Cisco IOS CLI – for configuring router interfaces and routing via command-line
- IP Subnetting – to divide the network into multiple subnets
- Static Routing – to enable communication between networks
- Networking Concepts – addressing, subnetting, interface configuration, routing
- macOS Ventura 13.7.4 (21H2)
Launch Cisco Packet Tracer:
Drag and drop End Devices for the 2 networks and 1 switch for each, connect the computers to its network's switch using Copper Straight-Through cables:
Choose a Router, drag and drop then connect both switches to it using Copper Straight-Through cables:
Double click the computers, select Desktop, IP Configuration then choose Static IPV4 adresses of your choice for each computer of the 2 networks, in this case we'll use 192.168.100.1 and 192.168.100.2 for computers 1 and 2 in the left network. Then 172.16.0.1 and 172.16.0.2 for computers 3 and 4 of the right network:
On the same screen choose Default Gateways for the networks, in this case we'll use 192.168.100.254 for the left one and 172.16.255.254 for the right one :
Double click the Router, go on Config then select the port corresponding to the left network on the Interface tab, which in this case is GigabitEthernet0/0/0 and turn it on. Then on the IPV4 address field type the Default Gateway of the left network which is 192.168.100.254:
Now select the port corresponding to the right network which is GigabitEthernet0/0/1, turn it on then address the Default Gateway which is 172.16.255.254:
Done! You have succesfully configured the Router for multiple networks:
