Flushing deletes all learned routes from the routing table.

To flush all learned routes, enter the following from the top level of the 
Administration Console:

All learned routes are immediately deleted from the routing table.

The system uses the default route to forward packets that do not match any 
other routing table entry. A system can learn a default route using RIP, or 
you can configure a default route statically.

If a system’s routing table does not contain a default route, either statically 
configured or learned using RIP, then it cannot forward a packet that does 
not match any other routing table entry. If it cannot forward a packet for 
this reason, then it drops the packet and sends an ICMP “destination 
unreachable” message to the host that sent the packet to notify it of the 
problem.

To statically configure the default route:

1 From the top level of the Administration Console, enter:

2 Enter the gateway IP address of the route.

The default route is immediately added to the routing table.

To remove a default route, enter the following from the top level of the 
Administration Console:

The default route is immediately removed from the routing table.
