Hi,

I am experiencing an issue with my hAP ax lite LTE6 running RouterOS 7.18.2.

After each reboot, the static IPv6 address I configured on the LAN interface (bridge) is no longer functioning properly. The address still appears in the configuration, but the interface is not reachable via IPv6 from other devices on the LAN — Router Advertisements also do not work at this point.

To restore proper IPv6 functionality, I have to manually disable and then re-enable the IPv6 address :

/ipv6/address/disable numbers=0;
/ipv6/address/enable numbers=0;

Once I do that, IPv6 works again.

This issue does not occur on another MikroTik router with identical configuration but a different model (CCR2116 and CRS328), so it seems specific to this device or hardware/firmware combination.

thanks.

If you believe it's a RouterOS bug: help.mikrotik.com is your best recourse.
If you think it could be a misconfiguration: need to see the config.

Honestly, I think it is a bug.
I will open a ticket, but it is strange that nobody already post about that..
