Chapter 9 High Availability : VRRP : Adding a VRRP virtual router to a FortiGate interface : VRRP Groups
  
VRRP Groups
A VRRP group includes all the relevant VRRP IDs and tracks the VRRP status to force the status of all group members if a VRRP domain is changed from master to backup. VRRP groups are configured through the CLI. The VRRP group ID can be between 1 and 65535. Use the following command to add a VRRP group to the port20 interface that includes the virtual route identifiers 25, 50, 66 and 70 to VRRP group 10
