Routing Commands

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. Specifying
Null0
as nexthop parameter adds a static reject
route. 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
Format
ip route <ipaddr> <subnetmask> [<nexthopip> |
Null0
] [<preference>]
Mode
no ip route
This command deletes a single next hop 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> [<preference>] |
Null0
}]
Mode
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
Format
ip route default <nexthopip> [<preference>]
