@jechen0648 I think everything can go with a single commit, can you rebase the PR ?

overriding frr image is no longer needed now.

remove frr image overriding in master and 5.0, still keep frr image overriding for 4.22 and 4.23 for now, they can be removed after frr bump is backported to 4.22 and 4.23

These tests aren't run in serial suite, so it's safe to remove TEST_SKIPS.

We shouldn't need this anymore. It only impacted 5.0 branch after k8s 1.36 rebase, but we fixed it with openshift/cluster-network-operator#3070

A bit confused here.
We wanted to ADVERTISE_DEFAULT_NETWORK=false because the scaled up node failed to come up since it did not have peering. We seem to be addressing that with this spare_ips approach. So then we should be able to run with ADVERTISE_DEFAULT_NETWORK=true?

I would explain in a comment why we need to do this here. It is not apparent how this step is affecting the pool reconciliation.

I don't understand why we are skipping Managed cluster should grow and decrease when scaling different machineSets simultaneously. Aren't we doing all the NUM_EXTRA_WORKERS=1, APPLY_EXTRA_WORKERS=true,ADVERTISE_DEFAULT_NETWORK=false just to get this important test to pass?

Add optional presubmit e2e-metal-ipi-ovn-dualstack-bgp-local-gw-serial for openshift/ovn-kubernetes on main, release-4.22, release-4.23, and release-5.0. Use a dedicated baremetalds-e2e-ovn-bgp-dualstack-local-gw-serial workflow so the shared local-gw workflow is unchanged. The serial workflow runs openshift/conformance/serial with extra workers, serial-specific TEST_SKIPS, and ADVERTISE_DEFAULT_NETWORK=false for extranet VRF-Lite coverage only. Enable TEST_SKIPS filtering for the serial conformance suite in baremetalds-e2e-test. Signed-off-by: Jean Chen <jechen@redhat.com> Co-authored-by: Cursor <cursoragent@cursor.com>
- Wait for MachineConfigPools Updated before BGP setup so pending MCO reboots from prior steps do not overlap with the test window. - Include spare baremetal hosts from ostestbm in external FRR neighbor config for dynamically provisioned nodes. - Patch FRRConfiguration CRD ASN fields to format int64 for K8s 1.36+. - Add ADVERTISE_DEFAULT_NETWORK (default true) so the serial workflow can disable default/pod network BGP peering while keeping extranet ads. Signed-off-by: Jean Chen <jechen@redhat.com> Co-authored-by: Cursor <cursoragent@cursor.com>
- Remove FRRConfiguration CRD int64 patch (fixed in openshift/cluster-network-operator#3070) - Document MCP wait before BGP setup in local gateway mode - Enable default-network BGP in serial workflow; spare_ips pre-seeds FRR peers for scaled workers - Unskip "Managed cluster should grow and decrease when scaling different machineSets simultaneously" - Update serial workflow documentation Signed-off-by: Jean Chen <jechen@redhat.com> Co-authored-by: Cursor <cursoragent@cursor.com>

Adds an optional, on-demand metal IPI presubmit for openshift/ovn-kubernetes that runs the dual-stack BGP local-GW workflow with the serial conformance suite, so EVPN disruptive / serial cases (e.g. from openshift/ovn-kubernetes#3161) can be exercised in CI when requested.
