Part of managing routing on a BIG-IP system is to add static routes for destinations that are not located on the directly-connected network. If you are using the route domains feature, you can specify a route domain ID as part of each IP address that you include in a static route entry.
Perform this task when you want to explicitly add a route for a destination that is not on the directly-connected network. Depending on the settings you choose, the BIG-IP system can forward packets to a specified network device (such as a next-hop router or a destination server), or the system can drop packets altogether.
|Use Gateway||Select this option when you want the next hop in the route to be a network IP address. This choice works well when the destination is a pool member on the same internal network as this gateway address.|
|Use Pool||Select this option when you want the next hop in the route to be a pool of routers instead of a single next-hop router. If you select this option, verify that you have created a pool on the BIG-IP system, with the routers as pool members.|
|Use VLAN/Tunnel||Select this option when you want the next hop in the route to be a VLAN or tunnel. This option works well when the destination address you specify in the routing entry is a network address. Selecting a VLAN/tunnel name as the resource implies that the specified network is directly connected to the BIG-IP system. In this case, the BIG-IP system can find the destination host simply by sending an ARP request to the hosts in the specified VLAN, thereby obtaining the destination host’s MAC address.|
