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

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

Hi Naveen,
Can you please share the DHCPv6 configuration of the client.
