Description Yolanda Robla 2021-06-16 06:34:20 UTC
Description of problem:

When deploying IPv6, it is needed to have some specific config to send the DUID, and specifically , send DUID using MAC address.
While this configuration is present on master nodes, it isn't on bootstrap. As a consequence, the bootstrap vm is not getting the right ip/hostname from dhcp.

It needs to get something like that, but on the bootstrap vm:

https://github.com/openshift/machine-config-operator/blob/master/templates/common/on-prem/files/NetworkManager-onprem.conf.yaml#L8

Version-Release number of selected component (if applicable):
4.8

How reproducible:
Setup an IPI deployment with ipv6, and configure DHCP6 server to give static ip addresses by mac. You will see that bootstrap VM is not getting it.


Actual results:

Bootstrap vm does not get any ip, or gets one from the non-static pool.


Expected results:

Bootstrap vm gets the desired IP and hostname.

Do we want to backport to 4.8?

> Do we want to backport to 4.8?

Probably a question for Yolanda - it should be simple to backport if needed, but I'm not sure which release is required to contain this fix.
