1. Proposed title of this feature request
2. What is the nature and description of the request?

In openshift installation phase I can see multiple multicast type traffics are initiated 

For example : 

1. VRRP multicast group-224.0.0.18 
2. ARP request for management of Virtual IPs
3. IGMPv3 Membership reports to 224.0.0.22

Product documentation does not include these topics, which is causing hurdles for installation (and probably it will cause issues in future).

Product document link : https://docs.openshift.com/container-platform/4.10/installing/installing_vsphere/installing-vsphere.html#installation-network-connectivity-user-infra_installing-vsphere

Request :

  - can we include zero network trust policy testing for openshift  ?
