Hi all, I am trying to set up a DHCP Ipv6 server, but when I connect my machine to the network My machine is not getting and IPv6 address neither the DNS address. If I statically configure an Ipv6 address on my machine I am able to ping my default Gateway “2800:410:3082:1::1” and go to the Internet it works fine with static, but I want it the Ipv6 address be assigned by DHCP.
Can anyone please assist me, thanks advance for your help.. This is the configuration I am Using,,
Danny

Hi Danny,
You seems to have only nebaled PD under DHCP pool on the server. Per my understanding, this will only provide PD prefix requested by Client and not the address as such.
Can you add "address prefix
ipv6 dhcp pool IPV6_1
prefix-delegation pool pool1 lifetime 1800 600
address prefix 2800:410:3082:1::/64
dns-server 2001:470:20::2
domain-name btl.net
!

I already tried that, when I go in Router(config)#ipv6 dhcp pool IPV6_1 I do not have an option to configure the
address prefix 2800:410:3082:1::/64,
This are the option I get under Router(config)#ipv6 dhcp pool IPV6_1
Router(config)#ipv6 dhcp pool IPV6_1
Router(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
import Import options
information Information refresh option
nis NIS server options
nisp NISP server options
no Negate a command or set its defaults
prefix-delegation IPv6 prefix delegation
sip SIP server options
sntp SNTP server options
I was reading on " ipv6 local pool" , But I don't know if that option can assign machines IPv6 and Dns addresses automatically by DHCP?????
I tried 2 other IOS that support IPv6 and both of them Including the one I am using dont give me the option to configure "address prefix 2800:410:3082:1::/64" under "ipv6 dhcp pool IPV6_1",
Is thier a differnt way of configuring a DHCP server for IPV6??? Any other suggestions are highly appreciated,
thanks for your help

danny
