Master EIGRP AS Numbers FAST and Boost Your CCNP Skills

will discuss the key conditions for establishing a good EIGRP neighbor relationship. To establish a good EIGRP neighbor relationship, there are three main points to consider: the Autonomous System (AS) number, the K values, and source detection. Firstly, the AS number must be consistent between the two routers. If the AS numbers are different, a neighbor relationship cannot be established. Secondly, the K values must be the same, which are used to calculate the metric value of the routing entries. If the K values are not consistent, the routers cannot become EIGRP neighbors. Lastly, source detection is essential, which involves checking the source IP address of the hello packet sent by the other party to ensure it is reachable and on the same direct link. If the source address is not reachable or not on the same direct link, a neighbor relationship cannot be established. By understanding these three key conditions, we can ensure a good EIGRP neighbor relationship and improve network performance.
