Comment 3 for bug 1871608

Hey

you should be able to reproduce it. While setting a second subnet linked to segment-2 withing the same network OVN try to update localnet port, which handles metadata requests, to add new IP address from second subnet.

The problem started happening recently after merging this valid patch [1].
It ensures that while adding a new fixed_ip to the port, the port has no other fixed ip from different segment configured.
In our case its exactly why it fails, because we are explicitly trying to add second fixed_ip.
