What does the abbreviation EIGRP stand for?

The abbreviation EIGRP stands for Enhanced Interior Gateway Routing Protocol. This protocol is developed by Cisco as an advanced distance-vector routing protocol that offers several improvements over traditional protocols.

EIGRP is characterized by its ability to send routing updates based on changes in the network, rather than routinely sending updates at set intervals. This efficiency leads to faster convergence times and reduced bandwidth consumption.

Additionally, EIGRP combines the benefits of both link-state and distance-vector protocols, which enables it to maintain a comprehensive view of the network topology while effectively managing routing metrics. The inclusion of the word "Interior" in its name signifies that it is designed for use within an autonomous system, rather than between autonomous systems.

In contrast, the other options contain inaccuracies that prevent them from being correct interpretations of the EIGRP acronym, as they either mix up the terminology associated with routing protocols or assign incorrect meanings to the components of the acronym.
