I have to use a new VRRP group since the R1/R2 old routers were CISCO and configured with HSRP.
The new routers R3/R4 are not CISCO and do not support HSRP.
So I will configure a new VRRP group to R3/R4 with the same VRRP IP as the old HSRP IP.The VRRP will broadcast a gratuitous ARP request containing the virtual router MAC address (according to the RFC that you provided) and the servers will update the arp table.
I want to avoid the worst case scenarion since the servers are not under my administrition and I could not clear the arp...
(otherwise the problem could not exist )
I have to be sure for the next "with a short downtime (shutdown HSRP Interfaces and acitvate/initialize VRRP) the servers should learn the new MAC-Address by the Gratuitous ARP and communication can go on"
