IPv6 DHCP pool configuration

[Cisco Freak]

Hello All,

I was trying to configure a IPv6 DHCP pool in a router in GNS3.

R1(config-dhcp)#ipv6 dhcp pool Test

R1(config-dhcp)#?
IPv6 DHCP configuration commands:
default Set a command to its defaults
dns-server DNS servers
domain-name Domain name to complete unqualified host names
exit Exit from DHCPv6 configuration mode
no Negate a command or set its defaults
prefix-delegation IPv6 prefix delegation
sip SIP Servers options

R1(config-dhcp)#ipv6 dhcp pool Test
R1(config-dhcp)#address prefix 2001:1111:1111:1111::/64
^
% Invalid input detected at '^' marker.

It doesn't give an option to configure a address prefix inside the DHCP pool. Any thoughts on this?

Hi CF,

Unfortunately, the IOS you are running does not yet support DHCPv6 for end clients (those that request IA_NA assignments). This DHCPv6 implementation only supports Prefix Delegation which is a different, unrelated functionality.

What IOS version are you running? The address prefix command has first been added in the 12.4(24)T release.

Best regards,
Peter

I am running c3640-a3js-mz.124-25d in GNS3. Let me try upgrading to newer code.
