ipv6 dhcp client request
Use this command to add an option to a DHCPv6 request.
Use the no form of this command to remove an option from a DHCPv6 request.
- Vendor-specific options allow a specific vendor to define a set of DHCP options that really make sense for their device or operating system.
- By default DHCPv6 uses four messages exchange (Solicit, Advertise, Request, and Reply) to obtain configuration parameters from a server. But when rapid-commit is specified,
dhcp6-clientwill include a rapid-commit option in solicit messages and wait for an immediate reply instead of advertisements.The Rapid Commit option is used to signal the use of the two message exchange for address assignment.
