A router interface need to run out of a switch, but I still have a routing …

in routers will be able to access route but the route was the second of IP routing has changed When the switch can be used, the router is a general routing the mouth, the other is the exchange of the mouth, you have to use it directly to exchange a few words on the switch and different.LAN routing from 1 to 2 port LAN routing natural change
Into a switch and LAN routing from 1 to 2 routing WAN port would be set up to the same IP gateways, and 2 routing network outside whole function of the router failure what ah?
1.SOHO routing If the device has followed a line of routers, will not set, then pick on the second SOHO routers on the LAN port, and then take the other machines in the rest of the population.
2.Will be set up, then take the second SOHO routers on the WAN port, the need for WAN port for the static IP, and to set up a gateway for SOHO routers on the LAN port address, this can free up a LAN port to use
