Hi, In fact,you can add several subinterface on a physical fastethernet port of a router with these subinterface encapsulated ISL or Dot1q,and give each subinterface a IP address.Many NIC can support 802.1q or ISL,so you can devide the physical NIC to several virtual NIC encapsulated ISL or 802.1q,and give each of them ip address,the defauft gateway ip of the router's subinterface.
