What is Default Route in Networking? How to Add Static Route to Cisco 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 route in one direction.

What is the Default Route?

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

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

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

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

Cisco Router Route Example

For a better understanding of the default routing logic in the router, 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?

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

R1(config)# ip route 0.0.0.0 0.0.0.0 10.1.1.2

The above command describes that an IP packet request sent to R1 will redirect to the 10.1.1.2 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 0.0.0.0 0.0.0.0 Serial0/1/0

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