must not match the IP address of any other VIP
If it matches the local IP address of that inter face or the subnets, the Vir tual Router will be defaulted to
have a priority of 255. See below.
Note:
A router currently in VRRP Master mode is the only device which will respond on the Vir tual IP address.
Consequently, a router using the Vir tual IP address as its Ethernet address will be non-responsive when not in
VRRP Master mode. Therefore, it is recommended that the Vir tual IP address not be used as the unique
Ethernet IP address of any network device.

Priority
in the range of 1 – 255 to the Vir tual Router. The default is 100. The priority of
a Vir tual Router will default to 255 if the Vir tual Router is the IP address owner. A priority of 255 indicates
that the Vir tual Router should operate in
Master
mode. Even a non-owner can have a priority of 255, and
thus operate in Master mode. You can configure only one Vir tual Router to be a Master by default (priority
of 255) for an inter face.

Preempt Mode setting.
