address for the DHCPv6 server will be the multicast address of ALL_DHCP_Servers

(FF05::1:3), if the interface parameter is configured only.

 Command Mode: Interface Configuration Mode.

 Default: By default, destination address for DHCPv6 relay is not configured.

 Usage Guide: This command is used to configure the DHCPv6 relay for the specified

interface, the address should be the address of another DHCPv6 relay or the address

DHCPv6 server. At most three relay addresses can be configured for an interface. To be

mentioned, the DHCPv6 relay stops working only if all the relay destination address

configurations have been removed. This command is mutually exclusive to “ipv6 dhcp

server” and “ipv6 dhcp client pd” commands.

 Example:

 Switch(Config-if-Vlan1)#ipv6 dhcp relay destination 2001:da8::1

2.16 ipv6 dhcp server

 Command: ipv6 dhcp server <poolname> [preference <value>] [rapid-commit] [allow-

hint]

o no ipv6 dhcp server <poolname>

 Function: This command configures the address pool which will be allocated by the

DHCPv6 server through the specified interface. The no form of this command will

remove the address pool configuration.

 Parameters: <poolname> is a string with its length less than 32, which designates the

name of the address pool which is associated with the specified interface. If the rapid-

commit option has been specified, the DHCPv6 server send a REPLY packet to the client

immediately after receiving the SOLICIT packet. If the preference option has been

specified, <value> will be the priority of the DHCPv6 server, with its value allowed

between 0 and 255, and with 0 by default, the bigger the preference value is, the higher

the priority of the DHCPv6 server. If the allow-hint option has been specified, the client

expected value of parameters will be appended in its request packets.

 Command Mode: Interface Configuration Mode.

 Default: DHCPv6 address pool based on port is not configured by default.

 Usage Guide: This command configure the DHCPv6 address pool which is applied by the

DHCPv6 server for the specified interface, as well as optional parameters. One VLAN

can bind many DHCPv6 address pools and assign the address for DHCPv6 request

packet from direct-link and relay delegation.
