$ cat <<EOF | oc apply -f -
apiVersion: k8s.ovn.org/v1
kind: EgressIP
metadata:
  name: demo-egress-ns
spec:
  # NOTE: these egress IPs are within the subnet range(s) in which my worker nodes
  #       are deployed.
  egressIPs:
    - 10.10.100.253
    - 10.10.150.253
    - 10.10.200.253
  namespaceSelector:
    matchLabels:
