Flushing a Route

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:

ip route flush

All learned routes are immediately deleted from the routing table.

Setting the Default Route

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:

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

ip route default

2Enter the gateway IP address of the route.

The default route is immediately added to the routing table.

Removing the Default Route

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

ip route noDefault

The default route is immediately removed from the routing table.
