Ordinary home router can be used as a switch. For a router with multiple LAN ports, it is easy to think that it is a combination of routing and switch functions that can be used only by the functions of its switch. At present, the use of the user is the largest TP-LINK router, the following example for the introduction.

Home router:

On the router, WAN is a separate port, LAN is generally a group of four. When the switch is used, the WAN port of the router is not used and the DHCP service in the router is disabled. All the network cables are connected to the LAN. Do not connect to the WAN. At this point the router's LAN port can actually be used as a switch.

Although the WAN port, the router is not set, LAN port can still be used as a switch, but some routers do not go through the above settings will cause the network instability or occasional dropped calls, so if you want the router when the switch, It is still necessary to make the exchange more stable.

Campus network router:

For the campus network router, can be seen as a strengthened switch. However, because the router works in the third layer of the network protocol, rather than the second floor of the switch, so the efficiency of the switch as a switch is not as efficient as the switch. Similarly, close the DHCP function, and then refer to the router instructions on the other instructions, the router will be able to use when the switch.
