IPv6 connectivity stopped somewhere after 14.2

Hi,

I have a number of DNS-servers and resolvers.
They have IPv4 + IPv6 configured.

The all run FreeBSD 14.2-RELEASE-p3

It seems somewhere along the update to p1...p3, IPv6 connectivity does not work for some of them.

I have the following hardware:
lagg0 from igb0 + igb1

There's a static default gateway configured, which I cannot ping anymore.

It seems only servers in one datacenter are affected. The same server-hardware and software-level in the other datacenter is fine.

Networking-department says, it's a software-problem...

Unfortunately, it's not ZFS, so no boot-environments.

I just booted FreeBSD 14.2-RELEASE-p2 and the problem persists.

None of those patches had anything to do with IPv6, not even indirectly.

I just booted 14.1 (ISO) and the problem seems to persist.
Networking-department wants none of it...
