I also use network.

Try adding (keep IPV6_PRIVACY=rfc3041)
net.ipv6.conf.default.use_tempaddr=2
net.ipv6.conf.all.use_tempaddr=2
in /etc/sysctl.d/ipv6_privacy_extensions and reboot.
No need for net.ipv6.conf.<nicN>.use_tempaddr=2
since /etc/sysconfig/network-scripts/ifup-ipv6 do this for you:
if [ "$IPV6_PRIVACY" = "rfc3041" ]; then
/sbin/sysctl -e -w net.ipv6.conf.$SYSCTLDEVICE.use_tempaddr=2 >/dev/null 2>&1
if [ $? -ne 0 ]; then
net_log $"Cannot enable IPv6 privacy method '$IPV6_PRIVACY', not supported by kernel"
