[Kea-users] ddns for a zone in multiple views

[Ben Sparks (bzsparks.com)]

Hi Peter,

Thank you, your suggestion pointed me in the correct direction. I'm now using the "in-view" zone option to share zones between views. Kea is now sending ddns updates to the primary view which are visible to all other views now. This also simplified the bind9 configuration.

Thanks again,

Ben
