Static Routing Protocol

• Static routing is not really a type of routing protocol, but it is a network routing technique because it usually managed by the network administrator for configuration as well as a selection of a network route. 
• Static routing can be used if there is the smallest network for route configuration and there is no need to exchange any change in route in the future.
• It is easy to configure, but it is done manually.
• It used for small organizations because the administrator needs to learn all the routes.
• It doesn’t handle failures outside the networks well because it reconfigured or any update done manually to fix the network problem.
• In static routing administrator constructs the routing table for every router by inserting all the entries of network (destination).
• Static routes have an Administrative Distance (AD) of 1.
• It is very secure because it can’t send any advertisement, like other routing protocols.
• In static routing protocol there is no routing algorithm or update mechanism are required (no need extra CPU and memory).
• If there is any link fails, then static route can’t reroute traffic automatically. It needs to reroute traffic manually.
