Windows NLB Exchange 2013 Multicast or IGMP Multicast thru FGT & FortiSwitches [SOLVED

Hi Members,

I see few posts partially around this subject, but no real solution arrived in there. We need to move a customer from Cisco infrastructure to a cluster of two fortigates (active / passive) and 6 fortiswitches and they have an Exchange 2013 cluster of two members. The equipment is on its way, so I don't have any way to test at my end. I am just going thru documentation or doing google search.

Current Cisco solution has the static arp entry for the Exchange cluster Virtual IP address to its multicast address, something like 

arp 192.168.10.50 03bf.ac20.141e arpa

mac address-table static 03bf.ac20.141e vlan 10 interface GigabitEthernet1/11 GigabitEthernet1/12 GigabitEthernet1/47 GigabitEthernet1/48

By default IGMP snopping is on both L3 and L2 stack, and L3 switch (stack of two) has IGMP querier set up 

ip igmp snooping querier vlan configuration 10 ip igmp snooping querier address 192.168.10.1

Will something like the following on the Fortigate firewall LAN interface correctly set up this static arp entry?

config system arp-table     edit  1     set interface internal     set ip 192.168.10.50     set mac 03:BF:AC:20:14:1E end

And is there such option available on the fortigate managed Fortiswitches?

And for Fortigate to act as IGMP querier:

config router multicast

set multicast-routing enable

config interface     edit internal     config igmp     set version 2     set pim-mode sparse-mode

end

Since this is an old and common technique used for Microsoft Clustering, I am hoping many of you have done this with Fortigate and Fortiswitches. So any advice will be much appreciated.
