ipv6 dhcp client
Use this command to configure DHCP client options to a DHCPv6 request.
Use the no form of this command to remove client options from a DHCPv6 request.
Note:
• ipv6 dhcp client information-request is used to get only stateless configuration parameters (i.e., without address).
• DAD-wait-time value is the maximum time (in seconds) that the client should wait for the duplicate address detection (DAD) to complete on an interface.
• DUID option override the default when selecting the type of DUID to use. By default, DHCPv6 dhclient creates an identifier based on the link-layer address (DUID-LL) if it is running in stateless mode (with -S, not requesting an address), or it creates an identifier based on the link-layer address plus a timestamp (DUID-LLT) if it is running in stateful mode (without -S, requesting an address).
