Explore EIGRP implementation with labs, covering terminology, packet types, and metric calculations, then configure default routes, route redistribution, and authentication in hands-on lab scenarios for the ccie encore 350-401 exam.
Explore the facts about EIGRP, Cisco's enhanced interior gateway routing protocol, including its distance-vector fundamentals, automatic equal-load balancing, incremental updates, and topology and neighbor discovery in large campus networks.
Explore eigrp features including IPv4 and IPv6 support, VLSM, metric calculations with K-values, equal/unequal load balancing, fast convergence, partial updates, and reliable transport using protocol 88.
Configure eigrp on headquarters and branch routers, assign interfaces, use wildcards for networks, verify neighbors, and debug hello packets to understand eigrp operation.
Explain eigrp packet types: hello, request, update, query, and reply, and how they establish neighbors, propagate routing updates, and ensure convergence using port 88 and multicast 224.0.0.10.
Explain how EIGRP wide metric uses a 64-bit metric with a 128-scale, enabled by named GOP configurations, to support high-speed interfaces from 10 gbps to 655 tbps.
Continue lab two by configuring named EIGRP with MD5 authentication across three branches, establishing neighbors and convergence, and verifying with show ip protocols and show ip eigrp neighbors.
Learn to summarize routes in eigrp and control advertisements using route maps and access lists, advertising HQ networks to branch routers while verifying with show commands.
Configure default route injection from the HQ router into branch routers using eigrp. Redistribute static routes and compare external vs internal routes.
Explore redistribution of networks between RIP and EIGRP in a lab, including named and classic redistribution and topology base steps. Verify redistribution across branches with show ip route.
Complete lab four by configuring eigrp stub to limit advertisements, redistribute an external static route into eigrp, and verify convergence and controlled propagation across the network.
In this course the author will explain the facts of eigrp, the feature of eigrp, the terminology used for eigrp. The author will show the difference in applying the eigrp under classic format and named format. The author will explain the formula used under both formats. In this course the student will learn about the metric calculation and how the 5 variables are used and the default the K values that are used by default. K1 and K3 are used for metric calculation by EIGRP. The author will use lab examples in calculating the eigrp metric calculation as part of the traffic engineering.
The author will also share important information on criteria to form EIGRP neighborship, these criteria should be met.
Autonomous system number should match. (AS is a group of networks running under a single administrative control) .
authentication should match (if applied). EIGRP supports MD5 authentication only.
subnet mask should be the same.
Hello timer- The interval in which EIGRP sends a hello message on an interface. It is 5 seconds by default. 5.
Dead timer- The interval in which the neighbor will be declared dead if it is not able to send the hello packet. It is 15 seconds by default.
The author shows why named eigrp will be used in high speed networks. The course has 4 important labs that cover the injection of default route, summarization, redistribution and stub. The author will configure the labs step by step so the student will learn how to implement the labs.
