I get the following error when trying to add a new IP pool to a VN within Fabric.
NCSO20812: One or more of the proposed pool(s) conflicts with at least one blocklisted IP address. Please choose a different pool address.
The IP pool subnet used to be part of a non fabric L3 switch which was discovered by DNAC for assurance. The SVI has been shutdown and the switch resynced. However when I try to add that subnet into my Fabric VN I still get the above error, like DNAC has remembered the last configuration.
Any ideas how to purge this information from DNAC?

Hi
Just to check, do you have integration with IPAM?

Actually IPAM is DHCP also.
I mentioned that because I got DNAC and Infoblox integration recently and it was necessary delete the DHCP entry on the Infoblox in order to be able to recriate on DNAC.
As DNA creates the dhcp by API on the infoblox, it reject because the scope already exist on dhcp server.
