IP Address Owner Features

IP address owner allows for the highest possible priority. A Priority of 255 is reserved for IP Address Owner. In a properly configured network, there will never be a virtual router with a higher priority (if there is another virtual router on the same subnet with a priority of 255, then the network is misconfigured with duplicate IP Addresses). This means that this virtual router will always assume Mastership if it is available to do so.

IP address owner features are:

• Requires less configuration. The Priorities are automatically assigned. Backup routers can use the default Priority settings and correct Master-Backup election will be achieved.
• Another IP Address does not have to be reserved for the virtual router. This is helpful if IP Addresses are scarce or limited.
• Preempt mode cannot be disabled. A virtual router that is IP Address Owner will always preempt and assume Mastership from a Backup router.
• A virtual router that is IP Address Owner will "overwrite" the MAC Address of the associated IP Address. In the ARP Cache Table, the MAC Address of the IP Address will be the VRRP MAC.
