Cisco Ccnp Certification Bsci 642-901 Exam Training: The Eigrp Adjacency
EIGRP is an important part of real-world networking as well as being a major topic on the 642-901 CCNP BSCI exam. As with any networking topic, before you try to master intermediate and advanced skills, you must master the fundamentals. It doesn’t get any more fundamental than the EIGRP adjacency process – and it doesn’t get any more important, because without that adjacency, we don’t have an EIGRP deployment!
In today’s CCNP tutorial, we’ll work with R1 and R2, two Cisco routers communicating over a serial interface. EIGRP is already running on R2’s serial interface, but was just enabled on R1’s serial interface. The EIGRP adjacency process begins with R1 sending an EIGRP Hello packet to the multicast address 224.0.0.10 in an attempt to find potential neighbors.
