[Kea-users] Option 81 and embedded devices

[Munroe Sollog]

We migrated from dhcpd to kea 2.0 almost 2 months ago. Everything has been
going well with the exception of a seemingly perplexing behavior difference
between the two DHCP implementations.

We have a lot of embedded devices of varying age all dhcping. All of these
devices had been working nominally when using dhcpd. However we are
noticing that when a device has a /technically/ non-compliant fqdn in the
option 81 field, kea will silently drop the DISCOVER packet.

Some of the devices we’ve been able to upgrade or fix the configuration,
but many devices can’t be fixed and would need to be replaced.

I’m curious if anyone else has noticed this behavior and if so has anyone
figured out a work around?
