Administering Routes 69

from the routing table immediately.
Flushing All Learned
Routes
Flushing deletes all learned routes from the routing table. To flush all
learned routes, enter the following at the top-level menu:
ip route flush
The Layer 3 Module deletes all learned routes from the routing table
immediately.
Setting the Default
Route
If you define a default route, the Layer 3 Module uses it to forward
packets that do not match any other routing table entry. The Layer 3
Module can learn a default route using RIP, or you can configure a default
route statically.
If the routing table does not contain a default route, then the Layer 3
Module cannot forward a packet that does not match any other routing
table entry. If this occurs, then the Layer 3 Module drops the packet and
sends an ICMP “destination unreachable” message to the host that sent
the packet.
You cannot configure the default route using the command line
interface; you must use the Web management interface for the Switch.
To set the default route, follow the procedure described in step 3 on
page 31.
Removing the Default
Route
To remove a default route from the routing table, follow the procedure
described in step 3 on page 31.
