Router Mode

Many of the routers offer different operation modes that you can use. However, some of them do not really tell you the best situations to use specific operation modes.

Basically, a router determines the fastest way possible, which is also usually the shortest way possible, in a particular network. It has the capability to route the packets through the most effective determined route.

Routers have the ability to allow hosts that aren’t practical on the same logical network, to be able to communicate with each other. Every router can receive chunks of data, which are called packets, on an interface. It will then forward the data packets to the intended location in the most efficient manner. The directing, or routing, of packets, is based on the routing table, by allowing routers to know where a particular network is found.

Aside from being a device, a router can be software on a computer. Routers should be, at least, connected to two networks. It is sort of a gateway to another network. Functionally, it is capable of generating traffic between logically separated networks.

The third layer, which is the network layer of the OSI model, is where routers operate. Understanding the OSI model is the key to figuring out differences between routers, gateways, and bridges. The network layer is responsible for moving packets from a particular port to another. It is based on addresses (L3) such as IPv4, IPv6, and IPX, or Appletalk, addresses.
