Hi,
I currently playing around with the HA and load balancing and I one question
appeared:
Scenario:
Multiple DHCP-Relays at different sites with both KEA-Servers as DHCP-Servers.
Both servers are available and the load balancing shifts the requests between
the two servers.
Incident: Because of a network issue Kea 1 is not available from the clients.
The network connection between Kea 1 and Kea 2 still works, so no partner-down
state.
Expected behaviour: Kea 2 sees the unacked clients of Kea 1 and sets Kea 1 in
partner-down state and handles all requests.
Experienced behaviour: Kea 2 still reports HA_BUFFER4_RECEIVE_NOT_FOR_US and
does not handle the requests
Is there a misunderstanding or configuration mistake on my side?
