IPv6 Track Interface not working after reboot

[kdemaria]

Hi all,

I have 23.09.1-RELEASE with Centurylink 6rd IPV6. It's been working well for years, but after recent updates the track interface IP is no longer being applied on reboot. If I simply save the interface, the V6 IP is assigned to the interface, and it works again. Any idea what's going on here, and how to fix.
