After some hours when ISP assign another IP then dhcpv6 add another second ipv6 on DHCPv6 interface. and then internet stop working.. after restart DHPv6 interface then old ipv6 address removed and show only one current ipv6 address and internet start working..
so, some time need manually restart interface when ip changed by ISP.
if i reboot CPE and get new ip from isp then also add new second ip to DHCPv6 interface and internet stop working. Also that time restart interface for remove old ipv6 address.
so, may be ipv6 should be automatically replaced with new ip when it changed by isp.
How to solve this issue?
AFAIR they call it prefix rotation and it is a normal behaviour. But my ISP doesn't change it until I release it intentionally. They added new button in WAN6 settings recently (UCI option existed for years) called "Do not send a Release when restarting" so I have semipermanent prefix. It doesn't change even after reboot. Have you tried playing with it?
where is "Do not send a Release when restarting" option?
Just like I said - WAN6 settings (very bottom of first tab).
You need to have updated packages. If you don't want to do it, just use "norelease" option from https://openwrt.org/docs/guide-user/network/ipv6/configuration

any command for enable norelease on luci interface?
uci set network.wan6.norelease='1'
what command to get current value of network.wan6.norelease?
root@OpenWrt:~# uci set network.wan6.norelease='1'
uci: Invalid argument
What version of OpenWrt are you using?
opkg list-upgradable | cut -f 1 -d ' ' | xargs opkg upgrade - update your packages and relogin to web-interface. Option should be there.
any effect on current settings on run this command ?
opkg list-upgradable | cut -f 1 -d ' ' | xargs opkg upgrade
It just updates packages which will affect Web-interface. Don't forget to logout and login again.
