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

[Peter Davies]

Hi Ben,
    In a kea-dhcp-ddns configuration file, each “dns-domain” definition 
can include
a single "key-name" statement, which refers to a previously defined TSig 
key.

Since kea-dhcp-ddns does not permit duplicate dns-domain definitions, 
assigning
multiple keys to the same domain is not possible.

One option to overcome this is to load the same zone in all views on 
your DNS
server. This could address the key limitation of the assignment.


If multiple forward zones were updated at each lease renewal, implementing
conflict resolution would be rather complex.

Kind Regards Peter
