requests from the clients, the destination should be the address of an external DHCPv6
relay or the DHCPv6 server. The no form of this command will remove the configuration.
Parameters: <ipv6-address> is the address of the destination to which the DHCPv6
relay forwards; <interface-name> or VLAN is the interface name or VLAN id which is
used for forwarding of DHCPv6 requests, <interface-name> should be a lay three VLAN
name, and the VLAN id is limited between 1 and 4096. If <ipv6-addess> is a global
unicast address, the interface parameter should not be configured; If <ipv6-address> is
an local address, the interface parameter is required be configured; The destination
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
16.15 ipv6 dhcp server
Command: ipv6 dhcp server <poolname> [preference <value>] [rapid-commit]
[allow-hint]
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.
