Routing Basics

The router must know the following details in order to route packets to the destined address

• Destination Address
• Neighbor routers from which it can learn about remote networks
• Possible routes to all remote networks
• The best route to each remote network

The router can learn these information from the neighboring router or an administrator can manually feed all these information. In dynamic routing, the routing table is automatically updated with all these information. In case of static routing an administrator has to manually feed in the network details of the neighboring as well as remote networks for the packet to be route and every time a device is added or removed, the administrator has to manually update each and every routing table
