Hi! I need to create route table entry for single IPv4 host address pointing to specified interface and link level address (MAC address), so that ARP protocol not used and supplied address always used instead. A command similar to the following one used to work in previous versions of FreeBSD (8.x AFAIR). It is still accepted as correct command, is processed and installs new entry to the routing table: # route -n add -host 192.168.0.0 -link lagg0:0.1b.21.bc.10.d0 -interface add host 192.168.0.0: gateway lagg0:0.1b.21.bc.10.d0 fib 0 # netstat -rn Routing tables Internet: Destination Gateway Flags Netif Expire ... 192.168.0.0 lagg0:0.1b.21.bc.10.d0 UHS lagg0 Nice entry, right interface with link level address, nice flags: host (H), no intermediate gateway required (no G flag). Still, it does not work as "ping 192.168.0.0" makes kernel to send ARP requests to lagg0 interface. They get no response as 192.168.0.0 is unpublished loopback address of neighbouring host having noted link level (MAC) address. So, not IP packets sent. How can I install static routing entry for such ethernet neighbour usable without ARP protocol these days? I use recent 10.3-STABLE/amd64. Eugene Grosbein
