Description Ben Nemec 2020-12-03 15:40:57 UTC

Description of problem: The initial version of the ipv6 infinite lease to static configuration script does not properly handle the case where infinite leases are used for initial deployment. It tries to modify the default connection, which ends up affecting both the provisioning and control plane interfaces. We need to wait for OVNKubernetes to create the br-ex bridge so we can configure that instead.

Note that unlike the ipv4 version of this feature, we only support OVNKubernetes for ipv6, so we don't need to handle the case where OpenShiftSDN is used.


How reproducible: Always


Steps to Reproduce:
1. Deploy baremetal cluster with DHCP server set to provide infinite leases


Actual results: Cluster fails to deploy because networking is configured incorrectly.


Expected results: Cluster deploys successfully
