ifconfig: ioctl(SIOCGIFAFLAG_IN6): Can't assign requested address

[hrsahu]

Hi All,
I was trying to add a IPv6 address to the Ifconfig en0 interface

sudo ifconfig en0 inet6 fe80::204:a3ff:fe12:13b4 add

command was successful

but when i do
ifconfig en0

this the following result

flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
 * *options=2b<RXCSUM,TXCSUM,VLAN_HWTAGGING,TSO4>
 * *ether 40:6c:8f:05:5d:f0 
 * *inet6 fe80::426c:8fff:fe05:5df0%en0 prefixlen 64 scopeid 0x4 
i[COLOR="Red"]fconfig: ioctl(SIOCGIFAFLAG_IN6): Can't assign requested address[/COLOR]
 * *inet 169.254.137.225 netmask 0xffff0000 broadcast 169.254.255.255
 * *media: autoselect (100baseTX <full-duplex,flow-control>)
 * *status: active

I can't get the configured Ipv6 link local address

could you please help me on this .. and it very urgent?
I am trying to use OS X as the IPv6 host and for IPv6 certification , Link local address should be added .

Hi All,
I did this following command to add a Ipv6 link local address to the interface en0

networksetup -setv6manual Ethernet fe80::204:a3ff:fe12:13b4 64 fe80::21f:d0ff:fe40:8bbd

but the observation is -
ifconfig doesn't show any IPv6 link address

$ ifconfig en0
en0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
	options=2b<RXCSUM,TXCSUM,VLAN_HWTAGGING,TSO4>
	ether 40:6c:8f:05:5d:f0 
	inet 169.254.138.147 netmask 0xffff0000 broadcast 169.254.255.255
	media: autoselect (100baseTX <full-duplex>)
	status: active

Please provide your input

Well according to the maul page :

setv6off networkservice] [-setv6automatic networkservice] [-setv6manual network service address prefixLength router]

See if you change you networksetup using the set6manual string.
