Hey Everybody, I've been fighting for a while now with trying to get a Vista pc getting an ipv6 IP from a cisco 8OO series ipv6 dhcp server. So what i basically want to achieve is my vista getting an ip out of the 1000:1000::3:0/116 pool I have created my ipv6 dhcp pool on the cisco: ipv6 dhcp pool local6pool prefix-delegation pool local6pool 0n my interface vlan1 i stated i want it to be a dhcp server: int vlan1 ipv6 address 1000:1000::3:1/116 ipv6 dhcp server local6pool And last from the /116 pool i defined for it, I want the client to just get one IP /128: ipv6 local pool local6pool 1000:1000::1:0/116 128 I tried to debug the ipv6 dhcp, but i get nothing at all there. Anybody might have a clue what the problem might be ? I've read something its RFC defined that you _have_ to use a /64 for DHCP. Could this be the cause? Am I missing certain settings, or is my prefix delegation wrong ? Thanks in advance for the hints. Daan
