    Hi All,
    I need a quick help.
    I was trying to add a IPv6 Link local address using Ifconfig

    sudo ifconfig en0 inet6 fe80::204:a3ff:fe12:13b4 add
    and the result is
    ifconfig: ioctl(SIOCGIFAFLAG_IN6): Can't assign requested address
    again I tried using
    networksetup -setv6manual Ethernet fe80::204:a3ff:fe12:13b4 64 fe80::21f:d0ff:fe40:8bbd
    but interface en0 doesn't show any Ipv6 link local address when I do ifconfig en0.

    result -

    $ ifconfig en0
    	ether 40:6c:8f:05:5d:f0 
    	inet netmask 0xffff0000 broadcast
    	media: autoselect (100baseTX <full-duplex>)
    	status: active
    please help me quickly.

    One more input on this -
    I tried ping6 -c 5 ::1 and there are responses.

    $ ping6 -c 5 ::1
    PING6(56=40+8+8 bytes) ::1 --> ::1
    16 bytes from ::1, icmp_seq=0 hlim=64 time=0.136 ms
    16 bytes from ::1, icmp_seq=1 hlim=64 time=0.283 ms
    16 bytes from ::1, icmp_seq=2 hlim=64 time=0.287 ms
    16 bytes from ::1, icmp_seq=3 hlim=64 time=0.285 ms
    16 bytes from ::1, icmp_seq=4 hlim=64 time=0.275 ms
    But system preference -> network -> status shows ,
    Ethernet is connected to the link local address "fe80::204:a3ff:fe12:13b4".

    but when i do ping6 from a peer machine which is connected to the MAC OS device, no response from the MAC OS. I checked from wire shark.
