Types of Routing
Routing is typically of 3 types, each serving their own purpose and offering different functionalities.
1. Static Routing
Static routing is also called as “non-adaptive routing”. In this, routing configuration is done manually by the network administrator. Let’s say for example, we have 5 different routes to transmit data from one node to another, so the network administrator will have to manually enter the routing information by assessing all the routes.
- Network administrator has full control over the network, routing the data packets to their concerned destinations
- Routers will route packets to the destination configured manually the network administrator.
- Although this type of routing gives a fine-grained control over the routes, it may not be suitable for large scale enterprise networks.
2. Dynamic Routing
Dynamic Routing is another type of routing in which routing is an autonomous procedure without any human intervention. Packets are transmitted over a network using various shortest path algorithms and pre-determined metrics. This type of routing is majorly preferred in modern networks as it offers more flexibility and versatile functionality.
- It is also known as adaptive routing.
- In this, the router adds a new routes to the routing table based on any changes made in the topology of the network.
- The autonomous procedure of routing helps in automating every routing operation from adding to removing a route upon updates or any changes made to the network.
3. Default Routing
Default Routing is a routing technique in which a router is configured to transmit packets to a default route that is, a gateway or next hop device if no specific path is defined or found. It is commonly used when the network has single exit point. The IP Router has the following address as the default route : 0.0.0.0/0.
What is Routing?
The process of choosing a path across one or more networks is known as network routing. Any kind of network, including public transit and phone networks, can use the routing principles. Routing chooses the routes along which Internet Protocol (IP) packets get from their source to their destination in packet-switching networks, such as the Internet. Routers are specialized pieces of network hardware that make these judgments about Internet routing.
