Command Mode Interface configuration
Usage Guideline The ipv6 dhcp client information refresh minimum command specifies the
minimum acceptable refresh time of the DHCPv6 client information. If the server
sends an information refresh time option of less than the configured minimum
refresh time, the configured minimum refresh time will be used instead.
This command may be configured in several situations:
• In unstable environments where unexpected changes are likely to occur.
• For planned changes, including renumbering, an administrator can grad-
ually decrease the time as the planned event nears.
• Limit the amount of time before new services or servers are available to
the client, such as the addition of a new Simple Network Time Protocol
(SNTP) server or a change of address for a Domain Name System (DNS)
server.
Setting ipv6 dhcp client information refresh minimum or no ipv6 dhcp client
information refresh minimum will not enable or disable the DHCPv6 client
prefix delegation function.
Example The following example configures a maximum of 2 hours before the DHCP
v6client information will be refreshed:
