Basic Router Configuration.

 

In this configuration article we will see how different networks can communicate using router, Router definition is given below.

A router is a device that connects two or more packet-switched networks or subnetworks. It serves two primary functions: managing traffic between these networks by forwarding data packets to their intended IP addresses and allowing multiple devices to use the same Internet connection.

Router which we are using in packet tracer file is 2911 which has two interfaces which mean we can two different networks, so we will configure interfaces for each network and also to get the functionality of routing (communication between networks) from router. After entering in global configuration, we will select the interface GigabitEthernet 0/0, which we want to configure for left network, Up the interface as in router by default interfaces are down as given below:

Figure 1: Router Interface getting up.

After this we will assign the probably first IP of that network which will also act as gateway for network, as shown below:

Figure 2: IP Assignment to Interface GigabitEthernet 0/0

Now we will configure second network which is attached to second interface GigabitEthernet 0/1 of router and run commands as shown above diagrams.

Figure 3: IP Assignment to Interface GigabitEthernet 0/1

Now we will assign IP Addresses from networks manually to nodes (PC’s) connected to interfaces and give them gateway which are addresses of interfaces as we have given up in figures.

                                         Figure 4: Manual IP to PC from network 192.168.100.1 range

IP Assignment to second network of Router.

First check node is pinging interface configure on router.

                                            Figure 6: Ping of node to left Interface.

After above task ping nodes of different networks and in our example, we will ping node PC2 and PC3.

Conclusion

In above all discussion we have configure interfaces on route for different networks communication and basic commands which are used for router configurations. In this article I have used wr for saving configurations from RAM into flash Drive of router.
