5 Advantages and Disadvantages of Static Routing | Drawbacks & Benefits of Static Routing

 

Static Routing: What is it?

Using the static routing technique, a router sets up its routing manually as opposed to using dynamic routing. Except when altered by a person, these configurations do not alter themselves after configuration.

Who is in charge of Static Routing?

Moreover, network administrators add entries to the routing table so that they can have both static and dynamic routes understood. In actuality, a network administrator handles all of the upgrades and other upkeep related to static routing.

Why would someone utilize Static Routing?

Although they are not mutually exclusive, the primary goal of employing a router is still the same for both static and dynamic routing. They improve routing efficiency and offer backups in case of emergencies. When the routers in the routing table do not match the IP addresses of the packets' final destinations, it is generally recommended. There are advantages and disadvantages to static routing as compared to dynamic routing.



I'll be focusing on 5 Advantages and Disadvantages of Static Routing | Drawbacks & Benefits of Static Routing in this post. You will learn about the pros and cons of adopting static routing through this post.

Now let's get started,

Advantages of Static Routing

1. Predictability

Static routing follows a relatively predictable route to the target. The network topology and design may change, but the router itself won't be affected. Users are always aware of the intended path.


2. Network Overheads

Static routing has virtually minimal overheads in contrast to dynamic routing. As a result, overhead is not imposed on routers or network links.


3. Configurations

Compared to large networks, configuring small networks is comparatively simple. To enable each router to connect to its designated network segment, the network administrator merely needs to make the necessary adjustments to each router. The router is not directly connected to these network parts.


4. Resource Requirements

Very little resources are needed for static routing. Here, additional hardware like CPU and memory is not required.


5. Bandwidth

CPU cycles are not used in the communication process when using static routing. Thus, it puts less strain on the CPU of the router. As a result, they use less bandwidth than dynamic routing protocols. 

 

 

Disadvantages of Static Routing

1. Maintenance

Network configuration is only easier on smaller networks; as a network's size grows, so does its complexity. Large numbers of routes are present in static configurations in particular, which can be extremely time-consuming to handle.


2. Updates

Not only is route updating in a big network known to be difficult, but route maintenance is also a challenge. It was necessary to update each route separately and in the proper sequence. There would be issues with internet connectivity if the routes were updated out of order.


3. Redundancy

Static routing does not automatically update in the event of a failure. To force the data to flow through an alternate path, users must manually modify the routes.


4. Input Errors

Because static routing is manually configured, it is susceptible to input errors. Almost certainly, mistakes can lead to errors. Errors can occur when configuring network information or routing paths by network administrators.


5. Protocol Support

When routing protocols are used with static routes, they are not as flexible. Less preference is always given to routes that are set up using the dynamic routing protocol.
