Advantages and disadvantages of static and dynamic routing protocols

Static Routing has the following purposes:
In a small network with no significant growth, it is easy to maintain the route table using static routes.
Static Routing can be routed to the remote network or from the remote network to the external network (see Chapter 2nd ).
Use a single default route. If a network cannot find a more matched route entry in the route table, you can use the default route as the path to the network.
 
Advantages and disadvantages of Static Routing
 
By comparison, we can list the advantages of each routing method. The advantage of one method is the disadvantage of the other method.
 
Advantages of Static Routing:
· Less CPU processing time.
· Easy for administrators to understand routing.
· Easy to configure.
 
Disadvantages of Static Routing:
· Time-consuming configuration and maintenance.
· Configuration error-prone, especially for large networks.
· The administrator needs to maintain the changed route information.
· Cannot expand as the network grows; maintenance becomes more and more troublesome.
· Operations can be performed only when you fully understand the entire network.
 
Advantages and disadvantages of Dynamic Routing
 
Advantages of Dynamic Routing:
· When a network is added or deleted, the Administrator does not need to maintain the route configuration much.
· When the network topology changes, the Protocol can be automatically adjusted.
· Configuration is not prone to errors.
· Good scalability, no problems during network growth.
 
Disadvantages of Dynamic Routing:
· Vro resources (CPU time, memory, and link bandwidth) are required ).
· Administrators need to have more network knowledge before configuring, verifying, and troubleshooting.
