1 physical interface for multiple vdoms

Hello ! On a FG300C with vdom option enabled, I have configured a lacp aggregate interface (8 physical interfaces), let' s call it " TRUNK_PROD" . TRUNK_PROD is associated with vdom root. I then have created several vdom, without any physical interfaces, but only vlan interfaces associated with " TRUNK_PROD" interface. ex : edit " TRUNK_PROD" set vdom " root" set type aggregate set member " port1" " port2" " port3" " port4" edit " VLAN100" set vdom " vdom01" set interface " TRUNK_PROD" edit " VLAN200" set vdom " vdom02" set interface " TRUNK_PROD" It is possible to make such a configuration on the web interface, but is it a good practise / officially supported by fortigate (official doc are welcome ) ? Do someone use a such configuration without problem ?
