CCNA: Scaling Networks Skills Assessment (EIGRP & OSPFv2) – Hands On Skills Assessment
Skills Assessment (EIGRP & OSPFv2) – Hands On Skills Assessment
Assessment Objectives
Part 1: Initialize Devices (2 points, 5 minutes)
Part 2: Configure Device Basic Settings (5 points, 30 minutes)
Part 3: Configure LAN Redundancy and Link Aggregation (6 points, 25 minutes)
Part 4A: Configure EIGRP for IPv4 Dynamic Routing Protocol (8 points, 30 minutes)
Part 4B: Configure OSPFv2 Dynamic Routing Protocol (8 points, 30 minutes)
Part 5: Verify Network Connectivity and HSRP Configuration (6 points, 15 minutes)
Part 6: Display IOS Image and License Information (5 points, 5 minutes)
Scenario
In this Skills Assessment (SA), you will create a small network. You must connect the network devices, and configure those devices to support IPv4 connectivity, LAN redundancy, and link aggregation. You will then configure EIGRP and OSPFv2 for IPv4 on the network and verify connectivity and HSRP. Finally, you will demonstrate your knowledge of IOS images and licensing.

Note: To find out how the router is configured, look at the interfaces to identify the type of router and how many interfaces the router has. There is no way to effectively list all the combinations of configurations for each router class. This table includes identifiers for the possible combinations of Ethernet and Serial interfaces in the device. The table does not include any other type of interface, even though a specific router may contain one. An example of this might be an ISDN BRI interface. The string in parenthesis is the legal abbreviation that can be used in Cisco IOS commands to represent the interface.
