IPv6 - Cannot enable DHCP client prefix delegation

[simon.dwyer]

Hi All

I am struggling turning on DHCP client prefix delegation on a dial 0 interface on at 1941w.

Everything can be configured apart from prefix delegation features. The following command is just are missing.

int dial 0

ipv6 dhcp client pb

I have configured this on a 877 router with no problems.  I have tried 15.0(1)M3 and 15.1(3)T.

Cheers,

Simon

Router(config)#int dial 0
Router(config-if)#ipv6 dhcp client ?
  information  Configure information refresh option
  request      Request

Thats all that is there.
