Introduction to Static Routes and Default Routes

What is a Static Route?

A Static Route is a route that is created manually by a network administrator. Static routes are typically used in smaller networks. In static routing, the routing table entries are populated manually by a network administrator.

The opposite of a static route is a dynamic route. In dynamic routing, the routing table entries are populated with the help of routing protocols.

The major advantages of static routing are reduced routing protocol router overhead and reduced routing protocol network traffic. The major disadvantages of static routing are network changes require manual reconfiguration in routers and network outages cannot be automatically routed around. Also it is difficult to configure static routing in a complex network.

What is a Default Route?

A Default Route (also known as the gateway of last resort) is a special type of static route. Where a static route specifies a path a router should use to reach a specific destination, a default route specifies a path the router should use if it doesn’t know how to reach the destination.

Default Route is the network route used by a router when there is no other known route exists for a given IP datagram’s destination address. All the IP datagrams with unknown destination address are sent to the default route.
