Hi Niall,
You need to share the dnssec-policy for no8.be in order to investigate
why it doesn't show the expected behavior, but I suspect that the policy
did not match the properties for the existing DNSSEC keys completely.
Best regards,
Matthijs

I have a couple of zones which I want to migrate from CLI-driven
signing to BIND9 automatic signing, while avoiding any change to
the respective parent-zone DS RR.
Status quo ante:
- https://dnsviz.net/d/no8.be/dnssec/
separate KSK, ZSK; both using alg 13
- https://dnsviz.net/d/jamm.ie/dnssec/
2048-bit KSK, 2x 1024-bit ZSKs (live and spare); all using alg 8
Preparation:
- Set up minimal stand-alone instance of BIND9 named,
configured with a **dnssec-policy** for each algorithm,
matching properties of existing DNSSEC keys, and with
`lifetime unlimited`;
- Deliver current key files and recently-signed copy of
zone files to this instance.
Expected behaviour on starting named:
- Zones are loaded;
- Spare ZSK for jamm.ie is retired;
- Other keys for each zone are accepted and retained;
- A CDS RR is generated for each zone, matching the current DS RR.
Observed behaviour:
- `named -v` shows `BIND 9.18.8 (Stable Release) <id:35f5d35>`;
- Zones are loaded;
- Spare ZSK for jamm.ie is retired;
- Other RSA/SHA-256 keys (for jamm.ie) are accepted and retained;
- A CDS RR is published for jamm.ie, matching the current DS RR;
- ECDSAP256SHA256 keys (for no8.be) are not accepted;
- New ECDSAP256SHA256 keys are created for no8.be;
- No CDS RR is generated for no8.be.
Unless I'm missing something, there seems to be a discrepancy
according to key type between the handling of RSA/SHA-256 and
ECDSAP256SHA256 keys respectively.
