Config ipv6 in a zone

Hello

im using solaris sparc 11 with a slorais 9 zone.
im failing to config ipv6 in the zone interface.
you can see my zonecfg info in the attached picture.
when i ran the ifconfig -a command on the solaris9 zone i can see only the ipv4 inteface. what am i missing here?

Thanks!
Guy

Solaris 9 didn't support IPV6, did it?
