What is the Administrative Distance of EIGRP and How Does It Affect Route Selection Process?

In EIGRP (Enhanced Interior Gateway Routing Protocol), the administrative distance is a value used to determine the trustworthiness of routing information received from different sources. The lower the administrative distance, the more reliable the route is considered to be.

The administrative distance of EIGRP is 90, making it a preferred routing protocol compared to others like OSPF with a higher administrative distance of 110. When a router receives routing information from multiple sources, it will choose the route with the lowest administrative distance, as it is perceived to be the most trustworthy and accurate.

This affects the route selection process by ensuring that the best route available based on administrative distance is chosen for forwarding packets, optimizing network performance and reliability.

In conclusion, the EIGRP administrative distance of 90 plays a crucial role in determining the priority of routes and influencing the decision-making process in selecting the most optimal path for data transmission.
