Hello everybody, I'm currently testing kea and I'm simulating possible scenarios. Doing so I tumbled over the following scenario:
In my test-network two kea-dhcp-servers are running using the High Availability Desing "load balancing". They are communicating over the control agent. If the primary sever stops working, the secondary does all the work. So far that's working great. However, what if at least one of the control agents stops working? Worst case: The control agent on the primary server. Now two perfectly fine working dhcp server are processing 100% of the incoming requests, because the secondary is not receiving an answer to its "ha-heartbeat" from the primary. That would cause a lot of trouble like multiple leases for the same client at the same time. Is there a way to prevent this scenario? Like, is it possible that the dhcpv4 or dhcpv6 server gets notificated in the exact moment when the control agent stops working and shuts itself down? Hence, only one dhcpv4 or dhcpv6 server would remain running in the network. Sadly, I couldn't find any available solution (like a hook or a deamon I just have to configure). Thank you for your time.
