Parameters
ip-address: IP address in dotted decimal notation.
mask: Subnet mask.
mask-length: Length of the subnet mask, that is, the number of successive bits in the subnet mask
whose values are 1.
interface-type interface-number: Interface type and interface number.
next-hop: Next hop IP address in dotted decimal notation.
preference-value: Priority of the route. This argument ranges from 1 to 255.
reject: Specifies the route to be unreachable. If you specify this keyword when executing this command,
any packet destined for the specified IP address is discarded, and the system informs the source that
the destination is unreachable.
blackhole: Specifies the route to be a blackhole route. If you specify this keyword when executing this
command, all outbound interfaces of the static route are the NULL 0 interfaces regardless of the next
hop. In addition, the system discards any packet transmitted along this route without informing the
source.
group-number: Detected group number ranging from 1 to 25.
Description
Use the ip route-static detect-group command to configure a static route, whose validity depends on
detecting results as follows:
The route is valid when the detecting result is reachable.
The route is invalid when the detecting result is unreachable.
Use the undo ip route-static command to remove an existing static route.
Examples
# Configure a static route to 192.168.1.5/24 with 192.168.0.2 as the next hop, and control the static
route validity using the detecting result of detected group 10.
Field
IP address to be detected
