OpenStack known issues¶
This section lists the OpenStack known issues with workarounds for the Mirantis OpenStack for Kubernetes release 23.1.

As a workaround, switch the encapsulation type to VXLAN in the
OpenStackDeployment custom resource:
spec: services: networking: neutron: values: conf: bagpipe_bgp: dataplane_driver_ipvpn: mpls_over_gre: "False" vxlan_encap: "True"
