Mode Interface Config
3.2.4 ip route
This command configures a static route. The <ipaddr> parameter is a valid IP
address, and
<subnetmask>
is a valid subnet mask. The
<nexthopip>
parameter is a
valid IP address of the next hop router. The optional
<preference>
parameter is an
integer (value from 1 to 255) that allows you to specify the preference value
(sometimes called “administrative distance”) of an individual static route. Among
routes to the same destination, the route with the lowest preference value is the route
entered into the forwarding database. By specifying the preference of a static route,
you control whether a static route is more or less preferred than routes from dynamic
routing protocols. The preference also controls whether a static route is more or less
preferred than other static routes to the same destination. A route with a preference of
255 cannot be used to forward traffic.
For the static routes to be visible, you must perform the following steps:
• Enable ip routing globally.
• Enable ip routing for the interface.
• Confirm that the associated link is also up.
Default preference—1
Format ip route <ipaddr> <subnetmask> <nexthopip> [<preference>]
Mode Global Config
3.2.4.1 no ip route
This command deletes all next hops to a destination static route. If you use the
<nexthopip> parameter, the next hop is deleted. If you use the <preference> value,
the preference value of the static route is reset to its default.
Format
no ip route <ipaddr> <subnetmask> [{<nexthopip> | <prefer-
ence>}]
Mode Global Config
3.2.5 ip route default
This command configures the default route. The value for <nexthopip> is a valid IP
address of the next hop router. The <preference> is an integer value from 1 to 255. A
route with a preference of 255 cannot be used to forward traffic.
Default preference—1
Format ip route default <nexthopip> [<preference>]
Mode Global Config
3.2.5.1 no ip route default
This command deletes all configured default routes. If the optional
<nexthopip>
parameter is designated, the specific next hop is deleted from the configured default
route and if the optional preference value is designated, the preference of the
configured default route is reset to its default.
