Assessment Task 3 – DoS environmentTopologyAssessment Sections:Part 1: Develop the IPv4 Address SchemePart 2: Cable Initialize and Reload DevicesPart 3: Configure Device IPv4, RIP v2 and Security SettingsPart 4: Test and Verify IPv4 End-to-End ConnectivityPart 5: Configure IPv6 Addressing on R2Part 6: Test and Verify IPv6 End-to-End ConnectivityPart 7: Use the IOS CLI to Gather Device InformationPart 8: Use PC-A to launch and monitor a DoS attackPart 9: Answer final questionsPart 10: Record all device configurations ScenarioIn Assessment task 3 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 routers. You will launch a DoS attack targeting the router and observe the attack taking place from PCA. In addition, you will test and document the network using common CLI commands. Required ResourcesPlease login to http://netlab.boxhill.edu.au and schedule a ‘VU21988 Advanced KALI Topology Lab’ Pod and ensure you give yourself at least four hours to allow a reasonable amount of time.NOTE: Access to the Console ports of the three network devices can only be achieved from PC-B. Multi-TAB Putty has been installed and preconfigured for ease of console access.
