Description ggrimaux 2024-04-23 08:59:09 UTC

Description of problem:
Client is doing the following:
Their IPV6 gateways always end in ---:??:28::
This format is valid and works outside of OpenStack.

-They render templates with a site specific file and get something like this:
external_gateway_ipv6: '???:???:???:cd:28::'
And:
rendered/overcloud-networks-deployed.yaml:            gateway_ip: '???:???:???:cd:28::'

-During overcloud deployment it fails with this:

The workaround is to add a 0 at the end ???:???:???:cd:28::0 and it works after rendering with it and deploying.

The question for you is why it is not accepting with :: only.

Version-Release number of selected component (if applicable):
OSP17.1.1

How reproducible:
100%

Steps to Reproduce:
1. Set a gateway IPv6 address ending with ::
2. Try to deploy your overcloud
3.

Actual results:
Deployment fails

Expected results:
Deployment succeed with IPv6 addresses ending with ::

Additional info:
We have templates and sos.
