Difference between Static and Dynamic Routing
Let us know the basic definition of routing. Routing is a type of process of creating the route for the data packets. There are two types of routing.
1. Static routing
2. Dynamic routing
Let us know the difference between static and dynamic routing. The routing is done in the network layer of the OSI model. As we said earlier, static and dynamic are the two types of routing.
Static Routing
• Static routing consists of no routing protocol. Static routing is a way of communication that doesn’t use any protocol.
• The network administrator will manually enter into the routing table.
Let us take an example to understand in detail the working of the static routing. Let say five routers that are connected to each other i.e router 1 router 2, router 3, router 4, router 5. If we want to send the data from router 1 to router 3, the route can be created in such a way that router 1 forwards the data to router 2 and this router 2 will forwards the information to router 3. Suppose if router 2 fails during the transmission, router 1 cannot decide the alternate route for the data packets.
To resolve this type of situation, the network administrator has to maintain another route manually in order to configure the alternate route. Now, then the data can be sent to the right destination address.
• The main drawback of static routing is that static routing requires support 24/7. The router cannot decide the alternate route for the data packets if any particular router has been failed.
• The static routing can also be a very time taking process, where the user needs to wait till the network administrator finds the alternate route for the data packets.
To overcome the disadvantage of static routing, dynamic routing has been introduced.
Dynamic routing
Let us learn what actually the dynamic routing is, and how it’s gonna solve the problems in static routing. Unlike static routing, dynamic routing uses the routing protocol. This routing protocol creates the route for the transmission of the data packets. The data is stored in the routing table after collecting all the information.
Let us take an example to understand the concept of dynamic routing. Let say five routers are connected to each other. In Dynamic routing, the administrator will not create the routing for the data packets. Instead of creating, the network administrator assigns a new routing protocol for the router.
Now, the newly assigned routing protocol can automatically decide the best route for the data packets. Unlike static routing, if any router fails, the dynamic routing protocol has the ability to automatically choose the alternate route for the data packets. These can decrease the work of the network administrator. And user no needs to wait for a long time as in static routing. It is one of the main advantages of dynamic routing.
In Dynamic routing, the routing protocol is used to route the packets and make entries in the routing table. It is mostly suitable for large network areas.
