AWS::EC2::IPAMPrefixListResolver IpamPrefixListResolverRule

Describes a CIDR selection rule.

CIDR selection rules define the business logic for selecting CIDRs from IPAM. If a CIDR matches any of the rules, it will be included. If a rule has multiple conditions, the CIDR has to match every condition of that rule. You can create a prefix list resolver without any CIDR selection rules, but it will generate empty versions (containing no CIDRs) until you add rules.
