Chapter 39 Configuring IPv6 Unicast Routing
Configuring IPv6
To delete a DHCPv6 pool, use the
no
ipv6 dhcp pool
poolname
global configuration command. Use the
no
form of the DHCP pool configuration mode commands to change the DHCPv6 pool characteristics.
To disable the DHCPv6 server function on an interface, use the
no ipv6 dhcp server
interface
configuration command.
This example shows how to configure a pool called
engineering with an IPv6 address prefix
:
Switch#
configure terminal
Switch(config)#
ipv6 dhcp pool engineering
Switch(config-dhcpv6)#
address prefix 2001:1000::0/64
Switch(config-dhcpv6)#
end
This example shows how to configure a pool called
testgroup
with three link-addresses and an IPv6
address prefix:
Switch#
configure terminal
Switch(config)#
ipv6 dhcp pool testgroup
Switch(config-dhcpv6)#
link-address 2001:1001::0/64
Switch(config-dhcpv6)#
link-address 2001:1002::0/64
Switch(config-dhcpv6)#
link-address 2001:2000::0/48
Switch(config-dhcpv6)#
address prefix 2001:1003::0/64
Switch(config-dhcpv6)#
end
This example shows how to configure a pool called
350
with vendor-specific options:
Switch#
configure terminal
Switch(config)#
ipv6 dhcp pool 350
Switch(config-dhcpv6)#
address prefix 2001:1005::0/48
Switch(config-dhcpv6)#

Enable DHCPv6 server function on an interface.
•
poolname
—(Optional) User-defined name for the IPv6
DHCP pool. The pool name can be a symbolic string
(such as Engineering) or an integer (such as 0).
•
automatic
—(Optional) Enables the system to
automatically determine which pool to use when
allocating addresses for a client.
•
rapid-commit
—(Optional) Allow two-message
exchange method.
•
preference
value
—(Optional) The preference value
carried in the preference option in the advertise message
sent by the server. The range is from 0 to 255. The
preference value default is 0.
•
allow-hint
—(Optional) Specifies whether the server
should consider client suggestions in the SOLICIT
message. By default, the server ignores client hints.

Verify DHCPv6 pool configuration.
Verify that the DHCPv6 server function is enabled on an
interface.
