3. Click the Submit Assessment button in the browser window to submit your work.
Introduction
In this assessment, you will configure devices in an IPv4/IPv6 network. For the
sake of time, you will not be asked to perform all configurations on all network
devices as you may be required to do in a real network or other assessment.
Instead, you will use the skills and knowledge that you have learned in the labs and
packet tracers in this course to configure the Town Hall router. In addition, you will
address the hosts on two LANs with IPv4 and IPv6 addresses and activate and
address the management interface of the Administration Switch.
You will receive one of several topologies.
You are not required to configure the IT Department Switch, and you will not be
able to access it in this practice skills assessment activity.
All IOS device configurations should be completed from a direct terminal
connection to the device console. In addition, many values that are required to
complete the configurations have not been given to you. In those cases, create the
values that you need to complete the requirements. For values that have been
supplied to you, they must be entered exactly as they appear in order for you to get
full credit for your configuration.
You will practice and be assessed on the following skills:
Configuration of initial IOS device settings
Design and calculation of IPv4 addressing
Configuration of IOS device interfaces including IPv4 and IPv6 addressing when
appropriate
Addressing of network hosts with IPv4 and IPv6 addresses
Enhancing device security, including configuration of the secure transport
protocol for remote device management
Configuration of a switch virtual management interface
Requirements by device:
Town Hall router:
Configuration of initial router settings
Interface configuration and IPv4 and IPv6 addressing
Device security enhancement, or device hardening
Secure transport for remote configuration connections as covered in the labs and
Packet Tracers in the course.

Step 1: Determine the IP Addressing Scheme.
Design an IPv4 addressing scheme and complete the Addressing Table based on
the following requirements.
a. Subnet the 192.168.1.0/24 network to provide 30 host addresses per subnet
while wasting the fewest addresses.
b. Assign the fourth subnet to the IT Department LAN.
c. Assign the last network host address (the highest) in this subnet to the G0/0
interface on Town Hall.
d. Starting with the fifth subnet, subnet the network again so that the new
subnets will provide 14 host addresses per subnet while wasting the fewest
addresses.
e. Assign the second of these new 14-host subnets to the Administration LAN.
f. Assign the last network host address (the highest) in the Administration LAN
subnet to the G0/1 interface of the Town Hall router.
g. Assign the second to the last address (the second highest) in this subnet to
the VLAN 1 interface of the Administration Switch.
h. Configure addresses on the hosts using any of the remaining addresses in
their respective subnets.
Step 2: Configure Host Addressing
a. Use the IPv4 addressing from Step 1 and the IPv6 addressing values provided
in the Addressing Table to configure all host PCs with the correct addressing.
b. Use the router interface link-local address as the IPv6 default gateways on the
hosts.
c. Complete the configuration of the server using the IPv4 addressing values
from Step 1 and the values in the addressing table

Step 3: Configure the Town Hall Router.
a. Configure the Town Hall router with all initial configurations that you have
learned in the course so far:
Configure the router hostname: Town-Hall
Protect device configurations from unauthorized access with the encrypted
privileged exec password.
Secure all access lines into the router using methods covered in the course and
labs.
Require newly-entered passwords to have a minimum length of 10 characters.
Prevent all passwords from being viewed in clear text in device configuration
files.
Configure the router to only accept in-band management connections over the
protocol that is more secure than Telnet, as was done in the labs and PT
activities. Use the value 1024 for encryption key strength.
Configure local user authentication for in-band management connections. Create
a user with the name netadmin and a secret password of Cisco_CCNA7.
b. Configure the two Gigabit Ethernet interfaces using the IPv4 addressing values
that you calculated and the IPv6 values provided in the addressing table.
Reconfigure the link local addresses to the value shown in the table.
Document the interfaces in the configuration file.
Step 4: Configure the Administration Switch.
Configure Administration Switch for remote management over Telnet.
a. Configure VLAN 1 as the SVI.
b. Configure IPv4 addressing according to your work in Step 1.
c. Be sure that the switch is able to accept connections from hosts on other
networks.
