DHCPv6-based address assignment

While IPv6 SLAAC is simpler and easier as it works as plug-and-play, it is not the only option for autoconfiguring the IPv6 address. DHCPv6 is another centralized address assignment option that can be used for address assignment and management. In this recipe, we will see how to analyze some of the most common DHCPv6 issues.

Getting ready

Ensure that you have a DHCPv6 server configured to assign an IPv6 address for the requesting clients. In Unix/Linux devices, ifconfig -a will list the IPv6 address configured on the interfaces. If you don't see the DHCPv6 assigned address, capture the packets using Wireshark in the LAN.

How to do it...

Check whether the end host sends a DHCPv6 solicit message. This is the first message that will be sent by the client to identify the list of available DHCPv6 servers offering a IPv6 address. The message will be sent with the source address as link-local address and the destination address will be a link-local scoped multicast address...
