A route is the sequence of devices through which network traffic is sent. Each device in this sequence, usually called a router, stores information about the networks it is connected to inside a route table. This information is used to forward the network traffic to the next router in the route.
Your XTM device automatically updates its route table when you change network interface settings, when a physical network connection fails, or when it is restarted. To update the route table at other times, you must use dynamic routing or add a static route. Static routes can improve performance, but if there is a change in the network structure or if a connection fails, network traffic cannot get to its destination. Dynamic routing ensures that your network traffic can reach its destination, but it is more difficult to set up.
