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.
EXAMPLE
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:
10. ipv6 dhcp server [ poolname | automatic ]
[ rapid-commit ] [ preference value]
[ allow-hint ]
Enable the 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.
11. end Return to privileged EXEC mode.
12. show ipv6 dhcp pool
or
show ipv6 dhcp interface
Verify DHCPv6 pool configuration.
Verify that the DHCPv6 server function is enabled on
an interface.
13. copy running-config startup-config (Optional) Save your entries in the configuration file.
