Description Aniket Bhat 2021-07-23 19:12:39 UTC

Description of problem:

In a v6 only ovn-k cluster, the management interface IP is not added to the address set used for classifying host network traffic. This causes the allow-from-router network policy to not work correctly on platforms where the endpoint publishing strategy is "HostNetwork"

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


How reproducible:
Always


Steps to Reproduce:
1.Create a single stack v6 cluster on vsphere or a platform where the endpoint publishing strategy is HostNetwork
2.Create allow from ingress network policy
3.try external access to service in the cluster that is v6

Actual results:
service is not reliably accessible since the v6 management IP is not added to the address set for classifying host network traffic

Expected results:
External access to a service in a single stack v6 cluster works reliably.
