Scenario
In this Skills Assessment (SA) you will configure the devices in a small network. You must configure a router, switch and PCs to support both IPv4 and IPv6 connectivity. You will configure security, including SSH, on the router. In addition, you will test and document the network using common CLI commands.

Instructions
Part 1: Develop an IP Addressing Scheme
Total points: 24
- Given the IPv4 specifications below, design an IP addressing scheme that satisfies the following requirements in an efficient manner:
| Network | Number of Hosts in Subnet A | Number of Hosts in Subnet B |
| 192.168.100.0/24 | 80 | 25 |
IP Addressing Worksheet
| Specification | Subnet A | Subnet B |
| Number Host bits needed for the subnet | ||
| IP subnet mask (binary) | ||
| New IP mask (decimal) | ||
| IP Subnet address | ||
| First IP Host address | ||
| Last IP Host address | ||
| Broadcast IP address |
Show your work on an additional piece of paper. Submit a photo of that paper with your lab. (5 pts)
- Record your subnet assignment in the table below.
- Assign the first IPv4 address of each subnet to a router interface
- subnet A is hosted on R1 G0/0/1
- subnet B is hosted on R1 G0/0/0
- Assign the last IPv4 address of each subnet to the PC NIC
- Assign the second IPv4 address of subnet A to S1
- List the maximum number of useable hosts per subnet
- subnet A is hosted on R1 G0/0/1
- Assign the first IPv4 address of each subnet to a router interface
| Description | Subnet A | Subnet B |
| First IP address | ||
| Last IP address | ||
| Maximum number of hosts |
- Record the IP address information for each device:
| Device | IP address | Subnet Mask | Gateway | Points |
| PC-A | 2 points | |||
| R1-G0/0/0 | N/A | 2 points | ||
| R1-G0/0/1 | N/A | 2 points | ||
| S1 | 2 points | |||
| PC-B | 2 points |
- Use the IPv6 address 2001:db8:acad::/48 and create two subnets for use in this network. Record the IPv6 addresses in the table. Do not use subnet 0.
| Assigned to Interface | IPv6 Subnet Address | Prefix Length |
| G0/0/1 | ||
| G0/0/0 |
- Record the IPv6 address information for each device. Use the first non-0s address for the router interface and the 16th address for the PC in each subnet. Do not change the PC’s IPv6 link local addresses.
Note: Use FE80::1 as the link-local address on both router interfaces.
| Device | IPv6 address | Prefix Length | Gateway | Points |
| R1-G0/0/0 | N/A | 3 pts | ||
| R1-G0/0/1 | N/A | 3 pts | ||
| PC-A | FE80::1 | 1.5 pts | ||
| PC-B | FE80::1 | 1.5 pts |
Part 2: Initialize and Reload Devices
Total points: 2
- Erase the startup configurations from the router and switch and reboot the devices.
