To configure VRRP6 on the VLAN interface with IPV6 configured, it is mandatory to enable vrrp-virtual-mac6 and set vrip6_link_local as shown on the below example.

# config system interface
    edit "<VLAN Name>"

            # config ipv6
                set ip6-address x:x:x::x/64
                set ip6-send-adv enable
                set vrrp-virtual-mac6 enable
                set vrip6_link_local xxxx::x:x:x
                    config vrrp6
                        edit 1
                            set priority <priority integer <-----1 to 254 range.
                           set vrip6 x:x:x::x
                       next
                    end

To verify the VRRP6 configuration, please execute the below command on the FortiSwitch CLI.

FSW# get route info6 vrrp
