Packet loss when Router Advertisement enabled



  • Hi all,

    I've got a strange situation. When I enable Router Advertisement with the option unmanaged, there is packet loss even in the same L2 segment.

    Here is the segment that I enabled RA.

    root@dns:~# ping -f -c 100000 10.79.1.2
    PING 10.79.1.2 (10.79.1.2) 56(84) bytes of data.

    --- 10.79.1.2 ping statistics ---
    100000 packets transmitted, 99869 received, 0% packet loss, time 76839ms
    rtt min/avg/max/mdev = 0.517/0.693/6.999/0.131 ms, ipg/ewma 0.768/0.649 ms

    And the segment RA disabled.

    root@dns:~# ping -f -c 100000 10.79.5.4
    PING 10.79.5.4 (10.79.5.4) 56(84) bytes of data.

    --- 10.79.5.4 ping statistics ---
    100000 packets transmitted, 100000 received, 0% packet loss, time 72443ms
    rtt min/avg/max/mdev = 0.524/0.660/6.982/0.097 ms, ipg/ewma 0.724/0.657 ms

    and this is the source.

    root@dns:~# ifconfig eth1
    eth1      Link encap:Ethernet  HWaddr 00:50:56:89:30:6e
              inet addr:10.0.0.2  Bcast:10.0.0.255  Mask:255.255.255.0
