[knot-dns-users] KSK Rollover - Lab Policy For Testing

Hi, we are testing knot at the moment and are struggling with the concept of automatic KSK rollovers. We are planning to fetch the current CDS for further automatic processing and try to figure out how to achieve a policy that performs KSK rollovers in a short period of time for testing purposes. Until now we have not seen any KSK rollovers and we are not sure why this is not happening. Can someone show me an example of a policy that schedules a KSK rollover within a very short period, let's say once a day? What policy parameters must be set? And what must be the zone's parameters in terms of TTL and SOA values (expire, refresh, etc)? Thanks a lot, Thomas
