network-route-static - Manage Static Routing
network route static COMMAND ... network route static add NETWORK [--gateway=GATEWAY,--unreachable,--prohibit,--blackhole] [--mtu=MTU] network route static remove NETWORK network route static list [--protocol=ipv6|ipv4]`
This command helps to manage routes.
The following commands are understood:
- add NETWORK …
A new route may be added by the add command. It is required to pass a valid network prefix NETWORK, which can be either IPv6 or IPv4.
For unicast routes, the --gateway=GATEWAY option must be passed, where GATEWAY is a valid IP address of the same protocol type as the network prefix is.
Use --unreachable, --prohibit, --blackhole can be used to create of that type. See ROUTE TYPES below for more information about these options.
The optional --mtu=MTU parameter defines the MTU along the path to the destination and must be an integer number. This will show you very detailed information about the given device.
- remove NETWORK
A route can be removed with this command.
NETWORK is the network prefix of an existing route.
Shows a list of all configured routes.
Output can be filtered by passing --protocol=[ipv6|ipv4].
A unicast route is the most common route in routing tables. It is a route to a destination network address, which describes the path to the destination. Use the --gateway=GATEWAY option to create such a route.
When a route is determined and the routing decision process returns a destination with an unreachable route type, an ICMP unreachable message is generated and returned to the source address.
This works like an unreachable route, but the returned ICMP message is an ICMP prohibited message.
Packets matching this kind of route are silently discarded. There will be no ICMP message sent to the source and no packet be forwarded.
