I am having trouble with finding the subnet and the IP address for the different devices. 1

Assessment Objectives

Part 1: Develop the IPv4 Address Scheme (15 points, 20 minutes)

Part 2: Configure Device IPv4 and Security Settings (30 points, 20 minutes)

Part 3: Test and Verify IPv4 End-to-End Connectivity (8 points, 10 minutes)

Part 7: Use the IOS CLI to Gather Device Information (10 points, 10 minutes)

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 IPv4 connectivity. You will configure security on the router. You will test and document the network using common CLI commands.

Required Resources

Packet Tracer

Part 1: Develop the IPv4 Addressing Scheme

Given an IP address and mask of __10.10.128.0 /17_____________ (address / mask), design a VLSM IP addressing scheme that satisfies the following requirements. Network address/mask and the number of hosts for Subnets A and B will be provided by your instructor.

Subnet

Number of Hosts

Subnet A

1000

Subnet B

120

The 0th subnet is used. No subnet calculators may be used. All work must be show in Excel.

The router interface will use the FIRST IP address in the subnet,
The switch management VLAN will be assigned the SECOND usable IP address.
The host computer will use the LAST usable address.

Write down the IP address information for each device:

Device

IP address

Subnet Mask

Gateway

PC-A

R1-G0/0

N/A

R1-G0/1

N/A

PC-B

Part 2: Initialize and Reload Devices

Step 1: Initialize and reload router and switch.

Provide the commands that will erase the startup configurations and VLANs from the router and switch and reload the devices.

Task

IOS Command

Erase the startup-config file on the Router.

Reload the Router.

Show routing table

Delete the vlan.dat file on the Switch

Show interface brief

Part 3: Configure Device IPv4 and Security Settings

Step 1: Configure host computers

Configure the host computers according to the IP scheme

Step 2: Configure R1

Configuration tasks for R1 include the following:

Task

Specification

Disable DNS lookup

Encrypt all passwords in the running configuration

Router name

EdgeRTR

Encrypted privileged exec password

ciscoenpw

Console access password

consolepw

Configure SSH for remote Access

Username: SSHAdmin

Encrypted Password: class123

Domain: ct.com

Modulus: 2048

MOTD Banner

Authorized Access Only

Interface G0/0

Set the description: LAN-A

Set the Layer 3 IPv4 address

Activate Interface

Interface G0/1

Set the description: LAN-B

Set the Layer 3 IPv4 address

Activate Interface

Step 3: Configure S1.

Configuration tasks for S1 include the following:

Task

Specification

Switch name

SW_LAN-B

Disable DNS Lookup

Configure DNS Domain Name

ct.com

Configure Management Interface (SVI)

Set the Layer 3 IPv4 address

Encrypt all passwords in the running configuration

Encrypted privileged exec password

ciscoenpw

Console access password

consolepbw

MOTD Banner

Authorized Access Only

Configure Telnet for remote access (all lines)

Password: vtypw

Configure the switch’s default-gateway

Part 4: Test and Verify IPv4 End-to-End Connectivity

Step 1: Verify network connectivity.

Use the ping command to test connectivity between all network devices.

Use the following table to methodically verify connectivity with each network device. Take corrective action to establish connectivity if a test fails:

From

IP Address

Ping Results

PC-A

EdgeRTR, G0/0

PC-A

EdgeRTR, G0/1

PC-A

S1 VLAN 1

PC-A

PC-B

EdgeRTR, G0/1

PC-B

EdgeRTR, G0/0

PC-B

S1 VLAN 1

PC-A

SSH to EdgeRTR

PC-A

Telnet to S1

In addition to the ping command, what other command is useful in displaying network delay and breaks in the path to the destination? (5 point)
