BGP Question FortiGate 7.4 -7.6

isnt it already supported ?

as far as i know, the 32bit community is split in two 16bit delimited by : , (0-65535):(0-65535)

config rule
edit 1
set set-community "65535:65535"

next

end

"222222:1" is not 32 bit standard community. It's 64 bit extended community. Therefore, you need to use "set type extended" in the community list. Then inside of the rules, you seem to need to use "set regex" instead of "set match" based on I can see in my 7.4.11.
The admin guide isn't so clear and rather confusing by putting both in the same rule.
https://docs.fortinet.com/document/fortigate/7.6.6/administration-guide/597174/community-lists

An example would look like this:
config router community-list
  edit "test-routes"
    set type expanded
    config rule
      edit 1
        set action permit
        set regexp "222222:1"
      next
    end
  next
end

Again, it's a string, not a number.
