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 – Assign a 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 – Toggle Preempt Mode either Yes or No . This setting specifies whether the router should
preempt the current Master for the ID, if its priority is greater than the current Master.
Note: A Vir tual Router will always preempt if it is the owner of the Vir tual IP address, regardless of the
Preempt Mode setting.
• Advertisement-Interval – Enter an Adver tisement-Inter val in seconds, after which the Master sends VRRP
adver tisement packets.
• Enable – Toggle Enable to Yes to enable this Vir tual Router; or No to disable it.
