Group 6: Routers and SNMP (we shall look at the practical part of this in class)
Routers are network devices that operate at the network layer (layer 3) of the OSI model that are
employed to connect two or more networks. They serve three primary purposes. First, they route
network traffic based on predetermined rules or routing tables. Second, they segment frames for
transmission between LANs. For example, they can frame 10-Mbps Ethernet LAN frames for
transmission on a 16-Mbps token ring LAN or a frame relay connection WAN.
Third, routers provide the ability to deny or block unauthorized traffic. This can be accomplished
through filtering commands that limit certain protocols (i.e., http, ftp, snmp) or by employing
access lists that control the IP addresses that are allowed through.
