ROUTING

ROUTING
There are three ways to control routing decisions on your router:
1-Static routes
2-Default routes
3-Dynamic routes

1-Static Routes :

A static route is the basic kind of routing that is used in Cisco routers.
The working principle of Static Routing depends on the manually defined paths. To route a packet to the pre-defined destination, the routes on the Cisco routers should be manually defined.
The area of usage is especially small networks that have small bandwidths. This kind of routing is useful only if the routing paths are not changing rapidly. Please keep in mind that, rapidly changing routes causes network connectivity failures which results packet losses. If you change the route, please change the routing path that you defined in the Cisco Router.
