What is Dynamic Routing Protocol in Network?

Dynamic Routing works more specific than Static. The static routes are manually configured, and dynamic routes are automatically created by the Router.

What is Dynamic Routing?

The dynamic routes created are propagated by hello packets sent between routers at regular intervals. The topology map of the network is automatically shared between the Routers.

The subnets connected to each Router on the network are added once, and the Routers then share the routing table among themselves.

As a result of errors on the network, routes are recalculated and Routers update the routing tables. For example, if a Router on the network fails, the other devices will wait for this destination for a certain period of time and update the routing tables after the time-out to remove the route from the topology tables.

When a new Router is added to the network environment, it can join the network immediately thanks to dynamic protocols. If a static route is configured on the new device instead of a dynamic protocol, the workload and time will increase considerably.

Dynamic protocols learn and discover all networks and record the best routes in their routing tables. The process by which a protocol calculates the best route is called the Routing Algorithm.

What is Routing Algorithms?

1. Distance Vector
2. Link State
3. Cisco-Specific Hybrid Routing Protocol (Hybrid)

1. Distance Vector

The Distance Vector selects the best path to the destination network. Each Router it passes is called hop. Hop Count, which is the least number, is considered the best route. Vector indicates the direction of the remote network. For example; The RIP protocol is a Distance Vector routing protocol.

2. Link State

The Link State routing protocol is also called Shortest-Path-First. In this algorithm, routers maintain 3 separate tables. These;

1. The topology of the Whole Network
2. Neighboring Devices
3. Routing Table

The Link State routing protocol is more advanced than the Distance Vector routing protocol. For example; OSPF is a link-state protocol.

3. Hybrid

This structure uses both the Distance Vector and the Connection State protocol. The EIGRP protocol for the hybrid is an example.
