Routing - Dynamic routing protocols
Dynamic routing protocols are protocols that operate on the control plane that are used to share information about routes to particular network destinations. Typically used with IPv4 and IPv6 networks, these protocols operate on Layer 3 of the OSI model.
Routing protocols fall into two broad categories: Interior Gateway Protocols (IGPs) and Exterior Gateway protocols (EGPs). You can find out more about these by exploring the differences between them.
There is currently only one EGP protocol that is in use today, and that is BGP, which is the de facto standard routing protocol used on the Internet.
There are several IGPs, which themselves fall into two categories based on the algorithm used to share routing information. These are Distance Vector and Link State routing protocols.
The following diagram more clearly depicts the relationship between these various types of dynamic routing protocols:

Other dynamic routing protocols include those used for Multicast traffic, such as Protocol Independent Multicast (PIM).
