Configures

Administrative distance for EIGRP

Default

External distance, 170; internal distance, 90

Description

This command sets the internal and external administrative distances for the EIGRP protocol. The administrative distance reflects the trustworthiness of a route’s source relative to other routing protocols. The internal-distance applies to internal routes, which are routes learned from the current EIGRP routing process (commonly called “autonomous system”). The external-distance applies to routes learned from other EIGRP routing processes. internal-distance and external-distance must be in the range of 1 to 255. Chapter 8 discusses the use of administrative distance and shows the default distances for the different routing protocols.
