Static routing is a form of routing that occurs when a router uses a manually configured routing entry, rather than information from a dynamic routing traffic. In many cases, static routes are manually configured by a network administrator by adding entries in a routing table, although this may not always be the case. Unlike dynamic routing, static routes are fixed and do not change if the network is changed or reconfigured. Static routing and dynamic routing are not mutually exclusive. Both dynamic routing and static routing are generally used in a router to maximize routing efficiency and to provide backups in case the dynamic routing information can not be exchanged. Static routing can also be used in stub networks, or to provide a gateway of last resort.
Applications
Static routing can have the following uses:
• Static routing can be used to define an exit point of a router when no other routes are available or necessary. This is called a default route.
• Static routing can be used for small networks that require only one or two routes. This is often more efficient since a link is not being wasted by exchanging dynamic routing information.
• Static routing is often used as a complement to dynamic routing to provide a fail-safe backup in case a dynamic route is unavailable.
• Static routing is often used to help transfer routing information from one routing protocol to another (routing redistribution).
