      Description of problem:

      When running the cnf-feature-deploy VRF test case withover lapping IPs on the OCP primary interface traffic does not flow over any of the secondary interfaces VRF and non-VRF. This test case fails on the Intel X810 card but passes on the Mellanox Connect-X5 card.

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

       

      How reproducible:

      Easily

      Steps to Reproduce:

      1. Deploy OCP 4.14-rc1 on BM cluster with SRIOV Intel X710 card
2. Run VRF Overlapping CNF-test

      Actual results:

        [FAILED] Unexpected error:      <*fmt.wrapError | 0xc0005d24e0>:       remote command [ping -I red -c5 10.128.2.194] error [command terminated with exit code 1]. output [ping: Warning: source address might be selected on device other than red.      PING 10.128.2.194 (10.128.2.194) from 10.128.2.193 red: 56(84) bytes of data.

      Expected results:

      ping -I red -c5 10.128.2.194 should be successful on both Intel X710 and MLX Connect-X5 card

      Additional info:

      The test also fails with 4.13.11

            Looks like this bug is far enough along in the workflow that a code fix is ready. Customers and support need to know the backport plan. Please complete the "Target Backport Versions" field to indicate which version(s) will receive the fix.

            The VRF test cases failed on our last zsstream test run. OCP 4.13.23 because a related bug effecting Intel SRIOV interfaces 710 and 810 Intel bug https://issues.redhat.com/browse/RHEL-7168

            There is a bug fix that was verified on 4.14 and has just now been backported to 4.13. At the next 4.13 zstream test run we can verify this bug.
