What is the administrative distance of EIGRP?

The administrative distance of EIGRP, or Enhanced Interior Gateway Routing Protocol, is 90. Administrative distance refers to the trustworthiness of a routing information source; lower values are preferred over higher values.

In networking, different routing protocols have different default administrative distances. For example, EIGRP is typically considered a more reliable source compared to other routing protocols like OSPF or RIP, which have higher administrative distances. This makes EIGRP a favored choice among many network engineers when reliability and the efficiency of route selection are critical.

To provide some context, RIP has an administrative distance of 120, making it less preferred than EIGRP when both protocols are present in the routing table. OSPF, on the other hand, has a default administrative distance of 110, which places it in between RIP and EIGRP. This hierarchy indicates the common practice of preferring EIGRP routes over others, thus enhancing the overall performance of the network.
