IPv6 addresses can not be deleted

RouterOS General
1

I have a strange issue:
I had some HE IPv6 addresses used in the past, which worked as expected. I added them to several pools and assigned them to different interfaces.
Now I deleted those assignments and pools. Everything is fine, just after a reboot, the old addresses appear again, this time with errors, since the pools are gone.

After deleting them and placing the proper new configuration, everything works fine, untill the first reboot, when the current config goes away (new pools stay in place, without issues), and the old IPv6 addresses reappear.
I tried clearing the configuration and restoring the config, disabling the ipv6 module and enabling it again to no avail. After each reboot, those old addresses are back.
Is a complete reconfiguration my only chance?

An export - delete configuration - import (in pieces) did the trick. But I still think this is an actual bug and should be addressed.

I have the same problem even in the current ROS 7.2 CHR
I don’t want to do an RSC export and import everything back again. I have more than 50 wireguard peers and the preshared-key is not exported in RSC. I really don’t want to fill everything again. Is there no other solution?

Write a script that saves the pre-shared keys to a file and then write a second one to place them back.

Or be patient and report it to Mikrotik support and hope they will fix that.

You need to use “export show-sensitive”. In v6, default was to export everything and optional hide-sentive parameter, in v7 it’s the oposite, default is what previous hide-sensitive did and optional show-sensitive if you want everything.

This is a bug. And the problem is not solved. Why did you say it was solved in the title?

I’m running 7.10.2 and don’t have an issue of reappearing deleted pools or addresses after a reboot.
