@salonichf5 let's mark this as a draft since it includes commits from your other open PR.

Can you actually get dual IP in the pipeline? AFAIK GitHub doesn't support ipv6

[salonichf5]

Yeah, the seems like that it is failing due to cluster not supporting Dual IP. Thinking on how to approach this.

actions/runner-images#668 (comment)

Maybe a way to get it working? Should look into it closely...

[salonichf5]

I am updating the kind create step with the current config for dual IP and adding the steps mentioned above !

[salonichf5]

2 out of the 3 tests pass for IPFamily in kind cluster. Unable to figure out why the 3rd is failing.

I am unable to reproduce the issue locally but have asked @lucacome for some help

Passing tests

• Service with IPv4 and IPv6 configured, when NGF is enabled on dual stack
• Service with IPv4 configured, Service with IPv6 errors on the HTTPRoute , when NGF is enabled on IPv4 stack

Failing Tests

• Service with IPv6 configured, Service with IPv4 errors on the HTTPRoute, when NGF is enabled on IPv6 stack ( traffic passes successfully through the IPv6 service)

[salonichf5]

Closing this PR because we need a dual IPFamily cluster to support IPv6 functional tests on kind but doesn't support IPv6.
