[Kea-users] kea-dhcp failover not working

[Kraishak Mahtha]

Hi Kevin,

We have that setup already, I use a tool that send packets using the
4.0.0.0 network interface, I tried that in standalone and it worked fine. I
have been using that tool for years and to my knowledge that has no issues,
I also tried with 192.168.0.0/22 network too, but still no luck.

And when you observe the echo command output file on both primary and
failover it shows waiting, I guess that is causing the issue , I think it
is something like both in recover recover status just like as ISC failover
stages, may be I could be wrong too.

Do you have any suggestions of how to debug more about the HA, Can we add
any more debugging for HA flow ?
