Static routing is table mappings that are established by the network administrator before the beginning of routing. These mappings will not change unless the administrator of the network makes the changes. Static routing is a relatively simple design, and works well where you can predict the network traffic, and the network is simple. The problem is that with today’s networks, the fact that static routing doesn’t change or react according to the network, they are really considered unsuitable. In the 1990’s the more dominant algorithms were dynamic routing algorithms. This is because they adjust to the network as it changes. It does this by analyzing incoming routing update messages. If there is a change in the network according to the message then the routing software recalculates and sends out new updated messages. The messages flow through the network, stimulating the routers to rerun their algorithms and

Unformatted text preview: change the routing tables accordingly. You can supplement dynamic routing algorithms with static algorithms where it becomes appropriate. A last resort router (this were packets are sent that become un-routable) can be used as a designated repository for all un-routable packets. This ensures that all messages are handled in some way. As a network administrator I would choose to use dynamic routing. This is because static routing when configuring an IP is normally for a single customer, where the dynamic routing allows you to assign a different IP each time a person logs on. I would also choose to use dynamic routing because static routing is a security risk. This is because the IP address never changes, this makes it easy hack into the IP address....
