What causes the VIP to failover when using VIP redundancy?

I am trying to setup VIP redudancy and would like to understand what circumstances cause a failover for the VIP. An example of what I would hope it does is if a redundant interface were to failover the VIP could be associated with it and failover as well or be configured to do so. Thanks in advance.

Re: What causes the VIP to failover when using VIP redundancy?

the CSS master is responsible to advertise itself on the interface you have Vip redundancy configured.

If the backup does not hear the master it will take over mastership.

another reason would be the lost a critical service.

You can define a service to be critical, and if it goes down, the active CSS will stop advertising itself as master forcing failover to the backup.

Does the backup take mastership over the interface redundancy and the VIP advertisement or just the interface redundancy in the first scenario?
