Background / Scenario
In this skills assessment, you are responsible for completing the configuration of the network so there is full
end-to-end reachability, so the hosts have reliable default gateway support, and so that management
protocols are operational within the “Company Network” part of the topology. Be careful to verify that your
configurations meet the provided specifications and that the devices perform as required.
Note: The routers used with CCNP hands-on labs are Cisco 4221 routers with Cisco IOS XE Release 16.9.4
(universalk9 image). The switches used in the labs are Cisco Catalyst 3650 switches with Cisco IOS XE
Release 16.9.4 (universalk9 image) and Cisco Catalyst 2960s with Cisco IOS Release 15.2(2) (lanbasek9
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.
Note: Make sure that the switches have been erased and have no startup configurations. If you are unsure,
contact your instructor.
Note: The default Switch Database Manager (SDM) template on a Catalyst 2960 does not support IPv6. You
must change the default SDM template to the dual-ipv4-and-ipv6 default template using the sdm prefer dual-
ipv4-and-ipv6 default global configuration command. Changing the template will require a reboot.

In this part of the Skills Assessment, you will complete the Layer 2 network configuration and set up basic
host support. At the end of this part, all the switches should be able to communicate. PC2 and PC3 should
receive addressing from DHCP and SLAAC.
Your configuration tasks are as follows:
Task# Task Specification Points
2.1
On all switches, configure IEEE 802.1Q trunk
interfaces on interconnecting switch links
Enable 802.1Q trunk links between:
• D1 and D2
• D1 and A1
• D2 and A1

Part 4: Configure First Hop Redundancy
In this part, you will configure HSRP version 2 to provide first-hop redundancy for hosts in the “Company
Network”.

4.1
On D1, create IP SLAs that
test the reachability of R1
interface G0/0/1.
Create two IP SLAs.
• Use SLA number 4 for IPv4.
The IP SLAs will test availability of R1 G0/0/1 interface
every 5 seconds.
Schedule the SLA for immediate implementation with no
end time.
Create an IP SLA object for IP SLA 4 and one for IP SLA 6.
• Use track number 4 for IP SLA 4.
The tracked objects should notify D1 if the IP SLA state
changes from down to up after 10 seconds, or from up to
down after 15 seconds.
