[Kea-users] Kea-DHCP4 HA-Maintenance and Hub-and-Spoke configuration

Hi,

the API command "ha-maintenance-start" will set the partner DHCP server into maintenance state.

So the command is usually being send to the machine that should "take over" the whole DHCP service.

How does this work in an hub-and-spoke configuration.

When an "ha-maintenance-start" command is send (via the kea-ctrl-agent) to the central "hub" machine, holding many different HA-relationships with "spoke" DHCP servers, will it set all "spoke" DHCP servers into maintenance?

If yes, will it be possible to just set one HA-relationship into maintenance mode?

Greetings

Carsten
