Virtual switch and VRRP protocol

    Hi everyone,

    I am new to ESXi and I'm trying to setup an environment with two VM placed on two ESXi6 servers.

    Each VM run a VRRP service instance; the active instance set mac and ip addresses and sends multicast vrrp packets on the network placing in idle mode other vrrp instances.

    Shutting down (only the service) active vrrp instance ,another instance (on priority base) became active (correctly) and set a virtual ip and a virtual mac address.

    When the first vrrp instance (with greatest priority) became active again,it set the virtual ip and virtual mac then sends multicast packet to place in idle other vrrp instance;

    The problem is that VM Ware virtual switch seems not forward multicast packets to Virtual machine (previously active); in this scenario both vrrp instaces remain active.

    I've set virtual swich in promiscuous mode enabling forged transmits and mac address changes, but the multicast packets don't reach the Virtual machine.

    Has anyone faced a similar problem ?

    Does Promiscuous mode require other configuration steps ?

    Thanks
