Hi,
I am experimenting with IPv6 and I can't seem to remove an IPv6 address=20
from an interface, eg I have..
[midget 22:11] ~ >ifconfig fxp0
fxp0: flags=3D8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu=20
1500
        options=3Db<RXCSUM,TXCSUM,VLAN_MTU>
        inet 10.0.2.1 netmask 0xffffff00 broadcast 10.0.2.255
        inet 10.0.2.3 netmask 0xffffffff broadcast 10.0.2.3
        inet 10.0.2.4 netmask 0xffffffff broadcast 10.0.2.4
        inet 10.0.2.7 netmask 0xffffffff broadcast 10.0.2.7
        inet6 2002:792d:8527::1:1 prefixlen 64
        ether 00:02:b3:32:2c:51
        media: Ethernet 100baseTX
        status: active

But I can't remove it, viz..
[midget 22:11] ~ >sudo ifconfig fxp0 -alias 2002:792d:8527::1:1/64
ifconfig: 2002:792d:8527::1:1/64: bad value
[midget 22:27] ~ >sudo ifconfig fxp0 delete 2002:792d:8527::1:1/64
ifconfig: 2002:792d:8527::1:1/64: bad value
[midget 22:27] ~ >sudo ifconfig fxp0 delete 2002:792d:8527::1:1
ifconfig: 2002:792d:8527::1:1: bad value
[midget 22:27] ~ >sudo ifconfig fxp0 delete 2002:792d:8527::1:1=20
prefixlen 64
ifconfig: 2002:792d:8527::1:1: bad value
[midget 22:27] ~ >sudo ifconfig fxp0 delete 2002:792d:8527::/64
ifconfig: 2002:792d:8527::/64: bad value

Anyone know the right way to do this? :)
