[Kea-users] kea-dhcp6 failing randomly

[Marek Greško]

Hello,

kea-dhcp6 complains abuout ip_vti0 interface down

which led to shutdown of the service when "service-sockets-require-all" was true,

2022-11-17 01:16:05.756 INFO [kea-dhcp6.dhcp6/2451.140297934552384] DHCP6_SHUTDOWN server shutdown

Why it complains also about ip_vti0 where kea is not configured to listen on it?

My interfaces-config section looks like this:

"interfaces-config": {
"interfaces": [ "bond0.10", "bond0.20" ],
"service-sockets-require-all": true,
"service-sockets-max-retries": 10,
"service-sockets-retry-wait-time": 5000
},

The kea-dhcp4 never complains about the interface with the same interfaces config.

Thanks for suggestions what am I missing here.

Marek
