Dynamic Host Configuration Protocol (DHCP) and IPv6

Discussion (20 Points): “Dynamic Host Configuration Protocol (DHCP) and IPv6” Please respond to the following:

Per the text, DHCP is a widely used technique for configuring the IP address and other parameters of IP devices. Identify what you believe to be the single most common configuration error and explain the reasons to support your position. Discuss the strategy you would use to fix the error that you have identified. Provide a rationale for your response.

There are a number of Cisco IOS tools and commands available for troubleshooting an OSPFv3 or Stateless IP Autoconfiguration problem. Select the tool that you would use to troubleshoot such a problem and provide a rationale for your response.

Response:

Per the text, Dynamic Host Configuration Protocol (DHCP) is identified as one of the most common ways of allocating Ipv4 addresses. DHCP provides its client a way to secure multiple pieces of IP address data from a DHCP server. Since it is the most common way to deploy Ipv4, we need to understand the DHCP process to recognize DHCP issues. The text shows us in a configuration where the service dhcp command turns on the routers DHCP service. Then suggests that even though the service should be turned on by default, when troubleshooting DHCP the router should be checked to verify if the service is turned on. Therefore, if I have to identify what I believe to be the single most common configuration error, I would suggest it would be forgetting to ensure DHCP was enabled on the router. I doubt I need reasons to support my conclusion unless there is a more common or simple DHCP configuration error. If the router’s DHCP service is not enabled, there can be no DHCP services. Period! Clearly, to fix this error you simply enable the router’s DHCP services with the service dhcp command.

Since there are a number of Cisco IOS tools and commands available for troubleshooting an OSPFv3 or Stateless IP Autoconfiguration problem, I would use several ipv6 and interface gigabitethernet0/0 commands as the tools to troubleshoot such a problem. According to the text, a trouble was presented on a network that uses stateless autoconfiguration. They used the show ipv6 interface gigabitethernet0/0 command to identify what was suppressed on the network. They used the show run interface gigabitethernet0/0 command to verify the configuration commnads on the interface. Then used the ipv6 ra suppress all command to stop sending suppressed data. Finally, the no ipv6 nd ra suppress all command was issued to generate an address and resolve the issue.
