Regression #13248

After installing @22.05.b.20220531.0600@, I noticed that the @System / Routing@ logs showed the following: * @2001:db8:4407:41c:20c:29ff:feae:75dc@ is the lan (ixv5) (ixv0) IPv6 address assigned from the tracked interface. * @fe80::20c:29ff:feae:75dc@ is the lan (ixv5) (ixv0) Link-Local address. * lan (ixv5) (ixv0) shows DHCPv6 Server and RA disabled in the GUI. The interface has @Tracked Interface@ set. * ixv0/2/3/4/6 ixv2/3/4/6 have DHCPv6 Server and RA enabled. The interface has IPv6 static addresses. <pre> Jun 5 13:03:26 radvd 51368 RDNSS address 2001:db8:4407:41c:20c:29ff:feae:75dc received on ixv0 from fe80::20c:29ff:feae:75dc is not advertised by us Jun 5 13:03:26 radvd 51368 RDNSS address 2001:db8:4407:41c:20c:29ff:feae:75dc received on ixv4 from fe80::20c:29ff:feae:75dc is not advertised by us Jun 5 13:03:26 radvd 51368 RDNSS address 2001:db8:4407:41c:20c:29ff:feae:75dc received on ixv2 from fe80::20c:29ff:feae:75dc is not advertised by us Jun 5 13:03:26 radvd 51368 RDNSS address 2001:db8:4407:41c:20c:29ff:feae:75dc received on ixv3 from fe80::20c:29ff:feae:75dc is not advertised by us Jun 5 13:03:26 radvd 51368 RDNSS address 2001:db8:4407:41c:20c:29ff:feae:75dc received on ixv6 from fe80::20c:29ff:feae:75dc is not advertised by us </pre> I also noticed that some hosts behind the firewall were getting two additional IPv6 addresses assigned from lan (ixv5), (ixv0), on top of the correct IPv6 address leased by the DHCPv6 Server. I rebooted the firewall and the issue persisted. I then re-saved the DHCPv6 Server and Router Advertisements config for @ixv5@ (the LAN which has @Tracked Interface@ set), and the issue was resolved. I ran a diff on the @config.xml@ file before and after the issue was resolved, and noticed that the difference was that the file contained an entry under @dhcpdv6@ for @lan@ (@ixv5@) with @<ramode>disabled</ramode>@ included. When I was experiencing the issue, the file did not contain any entry for @lan@ under @dhcpdv6@.
