    Hi!

    netstat says me there are no routes through 172.20.2.105:

    # netstat -rn | fgrep 172.20.2.105
    172.20.2.105 00:60:94:23:da:43 UHLS 10 8062 rl1
    # ifconfig rl1
    rl1: flags=89c3<UP,BROADCAST,RUNNING,NOARP,PROMISC,SIMPLEX,MULTICAST> mtu 1500
            inet 172.20.2.75 netmask 0xffffff00 broadcast 172.20.2.255
            inet 172.20.2.77 netmask 0xffffffff broadcast 172.20.2.77
            ether 00:50:ba:5d:09:24
            media: Ethernet autoselect (100baseTX <full-duplex>)
            status: active

    But route says there are:

    # route -n get 172.20.100.45
       route to: 172.20.100.45
    destination: 172.20.100.45
        gateway: 172.20.2.105
      interface: rl1
          flags: <UP,GATEWAY,HOST,MODIFIED,DONE,WASCLONED>
     recvpipe sendpipe ssthresh rtt,msec rttvar hopcount mtu
    expire
           0 0 0 22 17 0 1500 0

    And kernel really tries to send packets through 172.20.2.105
    that has static ARP entry but is down.

    How this can be?
