◆
DHCPv6 clients can obtain configuration parameters from a server
through a normal four-message exchange (solicit, advertise, request,
reply), or through a rapid two-message exchange (solicit, reply). The
rapid-commit option must be enabled on both client and server for the
two-message exchange to be used.
◆
This command allows two-message exchange method for prefix
delegation. When enabled, DCHPv6 client requests submitted from the
specified interface will include the rapid commit option in all solicit
messages.
◆
If the rapid commit option has been enabled on the switch with this
command, and on the DHCPv6 server, message exchange can be
reduced from the normal four step process to a two-step exchange of
only solicit and reply messages.
