would match a Class C network, and ff:ff:ff:ff is a route to a single host. (Note: the default is not always sensible; in
particular, if “<dest>” is 0.0.0.0 then it would be better for the mask to default to 0:0:0:0.)
“<cost>” (default 1) is the number of hops counted as the cost of the route, which may affect the choice of route when
the route is competing with routes acquired from RIP. (But note that using a mixture of RIP and static routing is not
advised.)
“<timeout>” (default 0, meaning that the route does not time out) is the number of seconds that the route will remain
in the routing table.
Note that the routing table does not contain routes to the directly connected networks, without going through a gateway.
TCP/IP routes packets to such destinations by using the information in the device and subnet tables instead. The
“route” command (with no parameters) displays the routing table. It adds a comment to each route with the following
information:
• How the route was obtained; one of
MAN — configured by the “route” command
RIP — obtained from RIP
ICMP — obtained from an ICMP redirect message
SNMP — configured by SNMP network management;
• The time-out, if the route is not permanent;
• The original time-out, if the route is not permanent;
• The name of the interface (if known) that will be used for the route;
• An asterisk (“*”) if the route was added recently and RIP has not yet processed the change
(the asterisk should disappear within 30 seconds, when RIP next considers broadcasting routing information).
Configuration saving saves this information. (Only the routes configured by the “route” command are saved or
displayed by “config”.)
Example:

ip route add default 0.0.0.0 192.168.2.3 0:0:0:0

13.5.28. routeflush
Syntax:
routeflush [<i/f>] [all]
Description:
Removes routes from the route table. If “<i/f>” is specified, only routes through the named interface are removed. If
“all” is not specified, only host routes (those with a mask of ff:ff:ff:ff) are removed. The “routeflush” command is
“hidden”, not shown by “ip help”.
Configuration saving saves this information.
Example:
DSL> ip routeflush ether all
DSL> ip routeflush
