Avoid conflicts in EMC ViPR network virtual IP addresses

Restrictions exist on the EMC ViPR virtual IP address when there are multiple ViPR instances in the same subnet.

This article applies to EMC ViPR 2.0.

When more than one ViPR instance exists in the same subnet, use care when allocating the ViPR virtual IP addresses, to prevent a conflict in the load balancer's virtual router ID. The virtual router ID is calculated using the virtual IP address configuration with the following algorithm:

For example, the following addresses in the same subnet would be invalid:
