On Windows 7 I have been using the command route add to add routing entries with a gateway. I now want to add a routing entry with no gateway, where the route is directly reachable.

Windows 7 calls such routes "on-link". I have tried creating on-link routes using the route add command and omitting the gateway entry, but that hasn't worked.

How can I create an on-link route in Windows 7?

You need to put 0.0.0.0 in the gateway entry to create an "on-link" route.

For example, enter the following command in cmd.exe or bash:

route add 10.10.10.100 mask 255.255.255.0 0.0.0.0

The answers here are right when it comes to ipv4, but ipv6 information is missing, so for the others like me looking for ipv6 equivalent, the "on-link" bit would be simply ::. So if you want to add a v6 route to, for example fe80::edc8:81a:d696:331/128 (single ip6), command would be:

route add fe80::edc8:81a:d696:331/128 ::

And in case you want to specify the interface, just add if <number> to the end of the command. Say, if you want to specify interface 10:

route add fe80::edc8:81a:d696:331/128 :: if 10

(usually interface 1 should be the loopback device)

You can add an interface using the command

route add 10.10.10.100 mask 255.255.255.0 0.0.0.0 IF <26>
