14.3 Static and Dynamic Routing Comparison
Static and Dynamic Routing Comparison Section 14: Enabling Static Routing There are two ways that a router can learn where to forward packets to destination networks that are not directly connected. Static Routing: The router learns routes when an administrator manually configures the static route. The administrator must manually update this static route entry whenever an internetwork topology change requires an update. Static routes are userdefined routes that specify the path that packets take when moving between a source and a destination. These administratordefined routes allow very precise control over the routing behavior of the IP internetwork. Dynamic Routing: The router dynamically learns routes after an administrator configures a routing protocol that helps determine routes. Unlike the situation with static routes, after the network administrator enables dynamic routing, the routing process automatically updates route knowledge whenever new topology information is received. The router learns and maintains routes to the remote destinations by exchanging routing updates with other routers in the internetwork. Up Next: When to Use Static Routing
