router.
To display the VRRP Configuration page, click Routing VRRP Advanced VRRP
Configuration.
Global Configuration
1. Use Admin Mode to set the administrative status of VRRP in the router to active or
inactive. Select enable or disable from the radio button. The default is disable.
2. VRID is only configurable if you are creating new Virtual Router, in which case enter the
VRID in the range 1 to 255.
3. Use Interface to select the Unit/Slot/Port for the new Virtual Router from the pull-down
menu.
4. Use Pre-empt Mode to select enable or disable. If you select enable, a backup router will
preempt the master router if it has a priority greater than the master virtual router's priority
provided the master is not the owner of the virtual router IP address. The default is enable.
5. Use Priority to enter the priority value to be used by the VRRP router in the election for the
master virtual router. If the Virtual IP Address is the same as the interface IP Address, the
priority gets set to 255 no matter what the user enters. If the user enters a priority of 255
when the Virtual and interface IP Addresses are not the same, the priority gets set to the
default value of 100.
6. Use Advertisement Interval to enter the time, in seconds, between the transmission of
advertisement packets by this virtual router. Enter a number between 1 and 255. The default
value is 1 second.
