Currently, IPv6 CIDRs are rejected during install-config validation. This was changed in master/4.4 via https://github.com/openshift/installer/pull/2829
Verify this bug with registry.svc.ci.openshift.org/ocp/release:4.3.0-0.nightly-2020-02-21-003712
Set the following parameters in install-config.yaml
- cidr: fd01::/48
- cidr: 10.0.0.0/16
- cidr: fd00::/48
With OPENSHIFT_INSTALL_AZURE_EMULATE_SINGLESTACK_IPV6=true, start the installation. Installer could create the expected subnets with ipv6 address CIDR. Move this bug to verified.
