This command is used to configure the prefix delegation client on the specified interface, an interface with prefix

delegation client enabled will send SOLICIT packets to try to get address prefix from the server. If the prefix is

retrieved correctly, the address prefix in the global address pool can be used by the ipv6 address command to

generate a valid IPv6 address. This command is exclusive with ipv6 dhcp server and ipv6 dhcp relay destination.

If the prefix delegation client is disabled for an interface, then the address prefix which is get from this interface

through prefix delegation client, will be removed from the global address pool. Also the interface address which is

generated by the prefix delegation client will be removed, and routing advertisement with the prefix will be disabled. If

any general prefix has been configured by the ipv6 general-prefix command, the same prefix learnt from prefix

delegation will be disagreed.

Example:

Switch(Config-if-Vlan1)#ipv6 dhcp client pd ClientA rapid-commit

29.13 ipv6 dhcp client pd hint

Command:

ipv6 dhcp client pd hint <prefix|prefix-length>

no ipv6 dhcp client pd hint <prefix|prefix-length>

Function:

Designate the prefix demanded by the client and its length. The no operation of this command will delete that prefix

and its length from the specified interface.

Parameters:

<prefix|prefix-length> means the prefix demanded by the client and its length.

Command Mode:

Interface Configure Mode.

Default Settings:

There is no such configuration in the system by default.

Usage Guide:

The system designates a prefix and its length on the interface for a client. If client prefix-proxy demanding function is

enabled on the interface and hint function is enabled on the switch, the user will have prior claim to the prefix it

demands and the prefix length when the server allocates them. Only one hint prefix is allowed in the system.
