Comment 64 for bug 1815101

Hi!

I am having trouble making this work in graceful manner.
Fresh Ubuntu 22.04, systemd 249.11-0ubuntu3.6, netplan 0.104-0ubuntu2.1.
Host has multiple interfaces (6 physical, 2 bonds, 3 vlans on those bonds) and multiple (20 to 30) IP addresses on those vlan interfaces.

EVERY time i issue `netplan apply` everything goes down and up again. Even with no changes to netplan configuration.
systemd-networkd logs interfaces going down and up again.

Changing anything in netplan config (like adding or removing one of IP addresses from single interface), doing `netplan generate` && `networkctl reload` restarts everything as well.

How I am supposed to simply add or remove IP address to existing interface without causing delay of about 5 seconds in network traffic, when all interfaces are being restarted?
Am I doing something incorrectly here?

Regards,
Marcin.
