Advantages and disadvantages of router

Router network can choose the best path across an inter network using dynamic routing techniques. Here this article gives information about advantages and disadvantages of router to know more details about it. 

Advantages of router :
  • It provides sophisticated routing, flow control and traffic isolation
  • Reduce network traffic by creating collision domains
  • Reduce network traffic by creating broadcast domains
  • Can connect different network architecture, such as Ethernet and token ring
  • They are configurable which allows network manager to make policy based on routing decisions
  • It can choose best path across the inter network using dynamic routing algorithms
  • It can reduce network traffic by creating collision domains and also by creating broadcast domains
  • Allow achieve loop so that redundant paths are available
Disadvantages of router :
  • Router are more expensive than bridge or reapeters
  • Router only work with rotatable network protocol, not all protocol are routable
  • Router are slower than bridge or repeaters because they must analyze data transmission from the physical to the network layer
  • Dynamic router communication causes additional network traffic 
  • Are relatively complex device 
  • Can require considerable amount of initial configuration 
  • They are protocol dependent devices which must understand protocol they are forwarding
