For example, routes for 10.10.8.112 and 10.10.8.254 have gateways of type AF_LINK (Ethenet addresses). I don't know about this specific problem, but adding a route with AF_LINK gateway can be done using a route(8) command, for example: # route add -host 1.2.3.4 -link :0.1.2.3.4.5 -ifp lo0 Which doesn't make any sense, and is presented only to demonstrate the ability to add AF_LINK gateway. The following command adds an "ARP route" through em0 which doesn't have a corresponding network, and is otherwise not possible to do with the arp(8) command: # route add -host 1.2.3.4 -link :0.1.2.3.4.5 -ifp em0 -iface add host 1.2.3.4: gateway :0.1.2.3.4.5 # arp -n 1.2.3.4 ? (1.2.3.4) at 00:01:02:03:04:05 on em0 permanent [ethernet] Cheers, --=20 Ruslan Ermilov ru@FreeBSD.org FreeBSD committer --TDVcAd+kFgbLxwBe Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (FreeBSD) iD8DBQFDkALFqRfpzJluFF4RAolDAKCFoTk/Ic22HRyHkkh+G1TGwqGpLwCeNZU8 aOSpTL+347I/O4XcuJRJME0= =UXi4 -----END PGP SIGNATURE----- --TDVcAd+kFgbLxwBe--
