Is this behavior exists from the beginning of KAME integration or available
in latest freebsd code? Because I was using a box which derives its ipv6
code from KAME project and the behavior was different from this. Also, in a
host which uses Red Hat Enterprise Linux AS release 4 (Nahant Update 4),
In host implementation, if I manually configure global ipv6 address via
ifconfig command then those addresses are not persistent after making the
interface DOWN and again UP, which is not the case for IPv4 addresses. Is
this an intentional behavior that all ipv6 address needs to be removed from
i
