EIGRP Configuration and Router Security

This course is included in our On-demand training solution.


Cisco’s proprietary routing protocol EIGRP is tremendously powerful with a large variety of features. EIGRP is the fastest converging IGP and is a great option in a totally Cisco-routed environment. Knowledge of EIGRP is critical for those working in an AS that uses this protocol. Additionally, knowing how to secure deployed Cisco routing hardware is essential for all network engineers. Because a compromised router exposes the entire internetwork to threats, engineers must be meticulous about taking every precaution that is practical to secure them. This course covers EIGRP configuration and fundamental router security topics. This course is one of a series in the Skillsoft learning path that covers the objectives for the Cisco exam Building Cisco Service Provider Next-Generation Networks Part 1 exam (640-875 SPNGN1). This exam counts toward the CCNA Service Provider certification.

Target Audience

This course is targeted at networking engineers who must interface with Cisco IOS, IOS XR and IOS XE devices. Additionally, those who have a need to understand technologies used in the service provider realm will benefit.
