A typical LAN is to connect a core switch with a layer-3 Switch to several Branch switches (not necessarily with layer-3 switching ). We assume that the core switch name is com, and the Branch switches are par1, par2, and par3 respectively, which are connected to the core switch through the light module of port 1; assume that the vlan names are counter, market, and managing ......
