In a secondary interface, you can have 1 interface with 2 addresses/subnets. A subinterface is different in that you create multiple interfaces, as opposed to the 1 in the secondary interface. You do all the addressing by creating sepreate logical interfaces. These subinterfaces look like seperate physical interfaces to the routing protocol.
