Configuring Static Routes

Deployment and configuration of static routes is appropriate when the Cisco ASAs cannot dynamically build a route to a specific destination. This may be because the device to which the Cisco ASA is forwarding the packets might not support any dynamic routing protocols. Another example when static routes are appropriate is when the network topology is small and uncomplicated. Static routes are easy to configure. However, they do not scale well in large environments. Dynamic routing protocols, such as RIP, OSPF or EIGRP, must be considered if the network is fairly large and complex.

It is strongly recommended that you have a complete understanding of your network topology before configuring routing in your Cisco ASA. A best practice is to have a network topology diagram on hand to refer to when configuring your Cisco ASA.
