IPv6 Prefix 0.0.0.0

Hi Guys,

I am just new to IPv6 and tried to test in the packet tracer. I configured the IPv6 pool, interface configuration on the router and then at the client end getting the dns server & domain name only. IPv6 address not coming up. Can you check the below configuration and debug results what is missing?


Configurations:

ip cef
ipv6 unicast-routing
!
ipv6 dhcp pool Lan1
 address prefix 2222:222:22::/64 lifetime 172800 86400
 dns-server 2222:222:22::10
 domain-name test.test

interface GigabitEthernet0/0
 no ip address
 duplex auto
 speed auto
 ipv6 address 3333:333::1/64
 ipv6 nd managed-config-flag
 ipv6 dhcp server Lan1

DHCP#sh ipv6 dhcp pool
DHCPv6 pool: Lan1
  Address allocation prefix: 2222:222:22::/64 valid 172800 preferred 86400 (0 in use, 0 conflicts)
  DNS server: 2222:222:22::10
  Domain name: test.test
  Active clients: 0

Debug Output:

Re: IPv6 Prefix 0.0.0.0

The client is asking for a prefix delegation (PD) rather than just an address. What is the client?
