Routing
• Routing is the process through which the router
learns the destination which is directly not
connected
To route, a router needs to do the following
• Know the destination address• Identify the sources from which the router can learn• Discover possible routes to the intended destination• Select the best route• Maintain and verify routing information
Rules of Routing
• Head Office Ethernet interface should be in the
same network as your Head office LAN and similarly
on Branch Office side. Show Diagram
• Head Office S0 and Branch Office S1 should be in same
network. Show Diagram
• Head Office LAN and Branch Office LAN should be in
different Network. Show Diagram
• All interfaces of Router should be in different network.

Types of Routing
• Static Routing: Uses a route that a network administrator
enters into the router manually
• Dynamic Routing: Uses a route that a network routing
protocol adjusts automatically for topology or traffic changes
Static Routing
• It is configured by Administrator manually.
• Mandatory need of Destination Network ID
• It is Secure & fast
• Used for Small organizations
• Administrative distance for Static Route is 0 and 1.
It is the “trustworthiness” of the routing information.
Lesser the Administrative distance, higher the
preference.
