A router with one Ethernet and Serial interface
A router with two Ethernet interfaces
A switch with one Ethernet and Serial interface
The three main functions of a router are: 1) Packet Forwarding, 2) Packet Switching, 3) Packet Filtering. Routers operate alongside switches in a reciprocal manner to provide access to the WAN. Switches deliver traffic to routers at the network boundary, to access the Internet or transmit information across the WAN. The network boundary is the demarcation point between the company's LAN and the WAN. Routers, who sit at the network boundary typically use Ethernet interfaces to connect to other devices inside the LAN, and use Serial interfaces to connect to devices outside the network boundary or WAN.
