multiple DHCP relays

Hi all,

Fortinet Support has just informed me that there is no option to add a second DHCP relay server to the interface config. I just want to ask the community if they agree?

config system interface

    edit "lan"

        set vdom "root"

        set dhcp-relay-service enable

        set ip 10.90.52.1 255.255.255.0

        set allowaccess ping https ssh snmp http fgfm capwap

        set type hard-switch

        set stp enable

        set role lan

        set snmp-index 4

        set dhcp-relay-ip "10.90.2.92" 

    next

end

I would like a second IP address in the set dhcp-relay-ip.

We are setting up a DHCP Failover as we are having a scheduled power maintenance in our head office which means the main DHCP server will be out of action for a few hours.
