7 Advantages and Disadvantages of Dynamic Routing | Drawbacks & Benefits of Dynamic Routing


Dynamic Routing: What is it?

Adaptive routing, or dynamic routing, is a networking standard that employs the best data routing strategies. Essentially, routing approaches allow routers to choose which routes to take from a source to a destination. Here, the routes are determined automatically so that they can select the optimal path, in contrast to static routing where you manually enter entries in the routing table.

Which protocols does dynamic routing support?

Numerous protocols, including all Exterior Gateway Protocols (EGP) and Interior Gateway Protocols (IGP), are supported by dynamic routing. The most used protocol among them is the Routing Information Protocol (RIP). 


Even while dynamic routing is the best option for large-scale network construction, there are certain unavoidable disadvantages. It is crucial that the computers consider both the advantages and disadvantages of each routing approach before choosing the optimal one.

I'll be outlining the 7 Advantages and Disadvantages of Dynamic Routing | Drawbacks & Benefits of Dynamic Routing in this post. You will learn about the pros and cons of adopting dynamic routing from this post.

Now let's get started,


Advantages of Dynamic Routing

1. Availability

By default, routers are able to communicate with one another. As a result, a new router can inform the others of its existence so that they can all adjust their routing tables appropriately. 


2. Automation

A procedure known as the Routing Process is part of dynamic routing and it operates between each router. By using this procedure, the connected routers receive all routing updates in an equal amount.


3. Adaptability

Not only can a dynamic routing network become larger, but it can also adjust to topological changes and reroute all traffic. 


 In particular, traffic is redirected without the requirement for manual labor if a network component fails. 

4. Configuration

The other routers in the network don't require any configuration when a new router is introduced. 


Only a new router required the configuration of the dynamic routing protocol for the network offers. 


5. Uptime

In addition to being intelligent, dynamic routing also has a faster reach. Users are able to observe increased uptime as a result. 


6. Latency

Dynamic routing can determine which networking link is the most responsive among all of them. As a result, consumers can benefit from increased network performance and reduced latency.

7. Problem Rectification

In addition to adjusting to configuration changes, dynamic routing has the ability to fix network issues. 


Stated differently, even in the event of a failure, the network will continue to operate. In actuality, a configuration and a network failure are the same thing. 

Disadvantages of Dynamic Routing 

1. Cost

Dynamic routing with a wavelength converter—which is well known to be quite costly—is a common practice in certain optical networks. 


Reducing the required wavelength is the aim of this. Nevertheless, the outcomes were discovered to be ineffective.


2. Resources

More CPU, RAM, and bandwidth are needed for dynamic routing. Therefore, it requires more resources for tasks like storing routing tables and calculating dynamic routes.

3. Communication

The dynamic routing protocol may not be able to communicate with some networked machines. 


Otherwise, these devices would detect a shared protocol. Static Routing is your sole option in this situation. 

4. Complexity

Dynamic routing frequently introduces additional network complexity, particularly during the installation phase. 


A router must continuously purge undesirable data from the routing table in order to adjust to network changes. The routing protocol becomes more sophisticated in situations like these.

5. Security

Because of their multicasting and broadcasting updates, dynamic routing is less secure than static routing. 


Using extra configuration parameters, including routing protocol and passive interface, is the only method to improve security. 

6. Bandwidth Shortages

Routers can exchange information about network topology by communicating with one another via the dynamic routing protocol. 


A big or unstable network connected to a low-speed link may use up a significant amount of bandwidth, causing shortages.

7. Administration Control

The routing protocol determines which routes the dynamic routes must select. They are unrelated to the network administrator.
