Static routing is a method of routing in which network routes are manually configured by a network administrator. This means that the paths data packets take through a network are predetermined and do not change unless the administrator alters them. Static routes are typically used in smaller networks where traffic patterns are predictable and do not require frequent updates. One advantage of static routing is its simplicity and low overhead, as it does not require complex protocols or additional resources to maintain. However, it lacks the flexibility of dynamic routing protocols like RIP or OSPF, which automatically adjust to changes in the network, making static routing less suitable for larger or more dynamic environments.
