SMF Manifest to bring up IPv6 on SmartOS

README

Need to open /usbkey/config and add

admin_v6_ip=xx:xx:xx/xx
admin_v6_gateway=yy:yy:yy

place ipv6 in /opt/custom/smf
place ipv6.xml in /opt/custom/scripts

ipv6

#!/bin/bash

. /lib/svc/share/smf_include.sh
. /lib/sdc/config.sh

load_sdc_sysinfo
load_sdc_config

ifconfig ${SYSINFO_NIC_admin} inet6 plumb up

if [[ -n "${CONFIG_admin_v6_ip}" ]] && [[ -n "${CONFIG_admin_v6_gateway}" ]]; then
  ifconfig ${SYSINFO_NIC_admin} inet6 addif ${CONFIG_admin_v6_ip} up
  route add -inet6 ${CONFIG_admin_v6_gateway} ${CONFIG_admin_v6_ip} -interface
  route add -inet6 default ${CONFIG_admin_v6_gateway}
fi

exit $SMF_EXIT_OK

Took me sometime to figure this out.To actually enable IPv6:

cd /opt/custom/smf
svccfg validate ipv6.xml 
svccfg import ipv6.xml 
svcadm enable site/ipv6
