What is the administrative distance of EIGRP routes and how does it impact route selection in the routing table?

Understanding the Administrative Distance of EIGRP Routes in Routing Tables

When it comes to EIGRP routes, the administrative distance plays a crucial role in determining the route selection in the routing table. The administrative distance is a value assigned to different routing protocols to indicate their trustworthiness or reliability in providing accurate routing information.

The focus keyword here is "Administrative Distance of EIGRP Routes."

In the case of EIGRP (Enhanced Interior Gateway Routing Protocol), the administrative distance is 90 for internal EIGRP routes and 170 for external EIGRP routes. This means that if the routing table receives multiple routes to the same destination from different sources, the route with the lowest administrative distance will be selected and added to the routing table.

Therefore, understanding the administrative distance of EIGRP routes is essential for network administrators to ensure the most efficient and reliable routing paths are chosen, ultimately optimizing network performance and connectivity.
