Large bgp community support in FortiOS

 I was working with a group that had fortigate and was not seeing large commnities. So we did some trial and testing and found out the UPDATE had the large community sent but the fortigate drops that community

e.g ( 10.10.10.2 sent standard/extended/large communities ) 

SOCPUPFGT02 # get router info bgp network 10.19.22.0/25

As you can see, we have no large communities in the list. Support provide the following link that explains what BGP supported RFCs.
