USES OF A ROUTER

for coupling networks or for connecting branch offices to a central office via VPN (Virtual Private Network).

Like bridges routers are also self-learning, as they can communicate their existence. to other devices and can learn of the existence of new routers, nodes and LAN segments
As explained earlier, they route traffic by considering the network as a whole. It shows that they use a high level of intelligence to accomplish this task. This characteristic makes them superior than hubs and bridges because they simply view the network on a link-by-link basis
The packet handled by router may include destination address, packet priority level, least-cost route, minimum route delay, minimum route distance, and route congestion level
Routers constantly monitor the condition of the network, as a whole to dynamically adapt to changes in the condition of the network
They typically provide some level of redundancy so that they are less susceptible to catastrophic failure
