Connected routes always take precedence over static or dynamically discovered
routes. In the event of a multiple entries match for a specified destination address, the longest match is
preferred. The longest match is the entry with the highest number of 1 bits in its Routing Mask.
Configure static routes using the route command from the global configuration mode to forward traffic for
specified nonconnected destination network. One disadvantage of a static route is that route entry will always
remain in the routing table, even if the specified gateway becomes unavailable. This is because no mechanism
exists for the Security Appliance to determine that the gateway address is not reachable. (This behavior is
prevented when using dynamic routing protocol.) If the specified gateway becomes unavailable, static routes
need to be manually removed. However, static routes are removed automatically from the routing table if the
specified physical interface goes down, and they are reinstated when the interface comes back up.
Static Route Tracking
Software Version 8.0 introduces another unique feature called Static Route Tracking. This feature supports the
capability to track the status of the next-hop IP address in the static route.
