+[IMPORTANT]
+====
+While provisioning more than one OCP cluster in same multicast domain with installer-provisioned vSphere installation,  make sure that the VRRP router IDs should not be conflicting.
+----
+$ podman run quay.io/openshift/origin-baremetal-runtimecfg:TAG vr-ids cnf10
+APIVirtualRouterID: 147
+IngressVirtualRouterID: 2
+----
+Where TAG is the release you are going to install, e.g., 4.9. Let's see another example:
+----
+$ podman run quay.io/openshift/origin-baremetal-runtimecfg:TAG vr-ids cnf11
+APIVirtualRouterID: 228
+IngressVirtualRouterID: 147
+----
+In the example output above two clusters in the same multicast domain with names cnf10 and cnf11 would lead to a conflict.
