What is Default Route in Networking? How to Add Static Route to Router

When configuring Routers on the network, the default route is usually added to the device that will access the Internet, and IP packets can go in one direction.

What is the Default Route and Understanding It on the Network

If no routing network address exists in the routing table on the Router, a Static way is configured to configure where IP packets go.

For example, if there is only one Router in the network environment, this device performs the routing task. Because IP packets coming to the local network are not likely to pass through another device.

If there are two or more Routers in the network environment, the Route is configured on the network device near the Modem or ISP device.

Therefore, when a computer that will access the internal network to the external network wants to access a network that does not exist in the routers’ routing table, it automatically uses the way and transmits IP packets.

Cisco Router Default Route Example

For a better understanding of its logic, carefully examine the following image. A static route is configured in R1 in the following image. Thus, unrecognized networks will be routed directly from R1 to R2.

Creating a Static Route in a Router

In small or large network topology, a route must be configured. Otherwise, IP packets will always drop when accessing unknown networks.

How to Create a Default Route?

The following command is applied to define the Route on a Cisco Router.

R1(config)# ip route

The above command describes that an IP packet request sent to R1 will redirect to the IP address.

Thus, R1 sends packets to R2 and fulfills the request of a PC on the LAN to display the webpage.

Another example of using the ip route command is as follows.

R1(config)# ip route Serial0/1/0

The interface and port number added to the end of this command belong to R1.
