Routing - Distance-vector routing protocol use cases

Distance vector routing protocols are a type of dynamic routing protocol which is used to exchange routing information between routing devices. Distance vector routing protocols like EIGRP and RIP are well suited for most network topologies, however, there are some use cases for which they are preferrable. Below is a list of such use cases.

Distance Vector Routing Protocol Use Cases

1. Small to Medium-Sized Networks: For smaller networks or branch offices, distance vector protocols like RIP are simpler to configure and maintain. Their minimal resource requirements make them a cost-effective solution for less complex environments.

2. Networks with Stable Topologies: In networks where changes are infrequent, distance vector protocols offer a straightforward routing solution. Their periodic updates are less of an issue in stable environments where dynamic response to changes is not a priority.

3. Developing Countries and Rural Areas: In regions where network infrastructure is being developed or is less dense, such as in certain rural areas of developing countries, the simplicity and lower resource demands of distance vector protocols can facilitate the initial deployment and expansion of network services.

4. VPN and Overlay Networks: Distance vector protocols, are well-suited for VPNs and overlay networks that span multiple Internet Service Providers (ISPs).

Each of these use cases highlights how the choice of distance vector routing protocols can be influenced by the specific needs of a network, including its size, complexity, stability, and the resources available for network management.
