Static or Dynamic
* As a network administrator for a company, you want to configure an IP route between two
routers. Of static and dynamic routing, which is more appropriate?
A router is a device that connects two LANs or WANs together. It has the ability to determine
the best known route to send packets to a destination. The factors used to determine the best
known route include not only the fastest route, but the most efficient. By using routing tables the
router can determine the route with the least amount of congestion or traffic, as well as the safest
route for the packets to travel. It doesnt always mean its the fastest route to the destination, but
it is the most efficient.
A router can be manually programmed by the network administrator to provide the most
efficient route. This is called static routing. In this type of routing, the network administrator
manually determines the best mappings to each destination before the routing begin. This is a
finite form of routing. Once the network administrator programs the routers, there is no change
in the routing pattern unless it is reprogrammed to a new route. If the pattern runs through a
congested network area, a router in the pattern is not functioning properly, or part of the network
is down, the router continues to try the same pattern because that is all it is programmed to
For todays larger networks, an unforgiving router mapping is not necessarily the most
efficient way of passing information within the network. When routing dynamically, software is
used to program a router to be forgiving. This means that the router remembers the best or most
efficient path, but if that path is not working, it will try the next most efficient route. The router is
able to do this by remembering the routing tables most often used in the network.
