ROUTER-CONFIG.

⚙️ Basic Router Configuration on Cisco Packet Tracer

This project focuses on router setup and configuration in Cisco Packet Tracer.
It shows how to assign IP addresses, enable interfaces, and set up basic connectivity.

📌 Steps I Took

1. Chose a Router

  • Used Cisco ISR4331 Router with no GigabitEthernet interfaces.
  • Navigated to the physical tab, switched off the router and inserted a NIC card(NIM ES2-4),in order to establish aa connection.
  • NB: Not all routers cointain Fast Ethernet or Gig. interface, thus a Network interface card is needed for connectivity.

3. Configured Default Gateway for PCs

Each PC had the router’s interface IP as its gateway

4. Verified Connectivity

Pinged router ↔ PC

Confirmed routing table with show ip route

5. Conclusion

Routers enable communication between networks, not just inside one. They are essential for WANs, VLAN routing, and internet access.

6. Files

router-config.pkt → Packet Tracer topology

router-commands.txt → CLI config

7. Learning Outcomes

-Configure router interfaces

-Assign IP addresses to router ports

-Use routers as gateways for PCs

NB:

2. Assigned IPs to Interfaces

Router> enable
Router# configure terminal
Router(config)# interface gigabitethernet0/0/0
Router(config-if)# ip address 192.168.1.1 255.255.255.0
Router(config-if)# no shutdown
