Adding a VRRP virtual router to a FortiGate interface
Use the following command to add a VRRP virtual router to the port10 interface of a FortiGate unit. This VRRP virtual router has a virtual router ID of 200, uses IP address 10.31.101.200 and has a priority of 255. Since this is the highest priority this interface is configured to be the master of the VRRP group with ID number 200.
config system interface
edit port10
config vrrp
edit 200
set vrip 10.31.101.200
set priority 255
