Objectives

Part 1: Build the Network and Configure Basic Device Settings

Part 2: Implement EIGRP for IPv6 and Named EIGRP

Part 3: Tune and Optimize EIGRP for IPv6

Background / Scenario

EIGRP for IPv6 has the same overall operation and features as EIGRP for IPv4. However, there are a few major differences between them:

IPv6 unicast routing must be enabled before the routing process can be configured.
In the absence of the router having any IPv4 addresses, a 32-bit router ID must be configured for the routing process to start.
EIGRP for IPv6 is configured directly on the router interfaces.

In this lab, you will configure the network with EIGRP for IPv6. You will also configure passive interfaces, propagate a default route, configure a summary route, implement routing protocol authentication, modify load balancing, and filter routes with a prefix list.

Note: This lab is an exercise in configuring the options available with EIGRP for IPv6. It does not necessarily reflect implementation best practices.

Note: The routers used with CCNP hands-on labs are Cisco 4221 with Cisco IOS XE Release 16.9.4 (universalk9 image). The switches used in the labs are Cisco Catalyst 3650 with Cisco IOS XE Release 16.9.4 (universalk9 image). Other routers, switches, and Cisco IOS versions can be used. Depending on the model and Cisco IOS version, the commands available and the output produced might vary from what is shown in the labs. Refer to the Router Interface Summary Table at the end of the lab for the correct interface identifiers.

Note: Make sure that the routers and switches have been erased and have no startup configurations. If you are unsure, contact your instructor.

Required Resources

· 3 Routers (Cisco 4221 with Cisco IOS XE Release 16.9.4 universal image or comparable)
