In the context of dynamic routing, what does IGP stand for?

In the context of dynamic routing, IGP stands for Interior Gateway Protocol. This term refers to protocols that are used for routing data within a single autonomous system, which is essentially a network or a group of networks under the control of a single organization. IGPs facilitate the exchange of routing information between routers within that autonomous system to ensure efficient routing and optimal data transmission.

IGPs, such as OSPF (Open Shortest Path First) and EIGRP (Enhanced Interior Gateway Routing Protocol), are designed to manage the routing within a limited scope compared to Exterior Gateway Protocols (EGPs), which operate between different autonomous systems. Since IGPs are specifically optimized for routing within a defined organizational infrastructure, they play a pivotal role in internal network efficiency and reliability.

By contrast, the other choices do not accurately represent the term IGP. For instance, "Internet Gateway Protocol" suggests a broader internet-level operation which does not align with the scope of an interior protocol. "Interconnected Gateway Protocol" and "Infrastructure Gateway Protocol" are not standard terms recognized in the field of networking, further distinguishing them from the accurate definition established for IGP.
