Trunk to basestation


I am trying to figure out how to pass a vlan to the lan side of the UE.
Need to be able to plug in customer facing routers that get put in a specific VLAN on the customer side.
I am thinking I need to look at bridge mode on the LGW and somehow trunk to the eNB and then bridge that over to the UE? Not sure if that is possible with this equipment or not?

Or if there is a different way to do what i am wanting to accomplish.
