Objectives

Part 1: Build the Network and Configure Basic Device Settings and Interface Addressing

Part 2: Configure and Verify Single Area OSPF for IPv4 on R1, D1, and D2

Part 3: Configure Default Route Propagation on R1 and Verify the Propagation

Part 4: Implement OSPF Network Optimizing Features

Part 5: DR and BDR Placement

Background / Scenario

In this lab, you will configure single-area OSPF version 2 for IPv4 on a multiaccess Ethernet LAN. This lab was specifically designed to use two Layer 3 switches instead of three routers to highlight how a Layer 3 switch can also be used to provide routing services.

Note: This lab is an exercise in developing, deploying, and verifying how OSPF operates and does not reflect networking best practices.

Note: The router used with CCNP hands-on labs is a Cisco 4221and the two Layer 3 switches are Catalyst 3560 switches. Other Layer 3 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.

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

Required Resources

·         1 Router (Cisco 4221 with Cisco IOS XE Release 16.9.4 universal image or comparable)

·         2 Switches (Cisco 3650 with Cisco IOS XE release 16.9.4 universal image or comparable)

·         1 Switch (Cisco 2960 with Cisco IOS Release 15.2(2) lanbasek9 image or comparable)

·         4 PCs (Windows with terminal emulation program, such as Tera Term)

·         Console cables to configure the Cisco IOS devices via the console ports

·         Ethernet cables as shown in the topology
