In this lab, learn and practice of how ISP assigns IPv6 prefixes to its customer's routers' LAN interfaces by using the technique called DHCPv6 Prefix-Delegation, you will configure both service provider and the customer sides.

Lab tasks:

ISP side:
1. Configure the local pool of IPv6 prefixes in the global configuration mode.
2. Configure IPv6 DHCP pool with the name DHCP_POOL using the local IPv6 prefix pool.
3. Assign the DHCP pool to the interface facing the customer's router.
4. Configure IPV6 static route for the prefix assigned to the customer.
5. Verify the prefix pool and save configurations.

Customer side:
1. On the interface facing ISP assign IPv6 address using SLAAC.
2. Under the ISP facing interface using DHCPv6 prefix-delegation command, specify the name of the pool for LAN interfaces to use.
3. Configure LAN interfaces with IPV6 addresses using the pool name specified in step 2.
4. Configure link-local address of FE80::1000 on all LAN interfaces, combine this step with step 3.
5. Verify DHCPv6 prefix delegation configurations.
6. Test connectivity from any PC to the ISP1 router's Loopback interface.

Command example:
ISP side:
ISP1(config)#ipv6  local pool my_prefix_pool 2001:DB8:FF00::/40 48
ISP1(config)#ipv6 dhcp pool DHCP_POOL
ISP1(config-dhcpv6)#prefix-delegation pool my_prefix_pool
ISP1(config)#interface G0/0
ISP1(config-if)#ipv6 dhcp server DHCP_POOL
ISP1(config-if)# exit
ISP1(config)#ipv6  route 2001:DB8:FF00::/48 g0/0 fe80::1000

Customer side:
Office-A(config)# interface G0/0
Office-A(config-if)#ipv6  address  autoconfig default
Office-A(config)#interface  g0/0
Office-A(config-if)#ipv6  dhcp  client pd ISP_PREFIX

Office-A(config)#interface  g0/1
Office-A(config-if)#ipv6 address ISP_PREFIX 0:0:0:1::1/64

Office-A(config-if)# exit
Office-A(config)#interface  g0/2
Office-A(config-if)#ipv6 address ISP_PREFIX 0:0:0:2::1/64

Office-A(config-if)# exit
Office-A(config)#interface  g0/1
Office-A(config-if)#ipv6  address fe80::1000 link-local

ISP side:
ISP1#show  ipv6 local pool
ISP1#show  ipv6 dhcp pool
ISP1#show ipv6  dhcp binding

Customer side:
Office-A#show ipv6 interface  brief
Office-A#show  ipv6 dhcp interface g0/0


Another great lab has been accomplished, next, I will make more troubleshooting labs based on technologies and commands in this project, this will help solidify knowledge you obtained by doing these configurations. I hope this was educational and you enjoyed this lab. Please rate upon completion, since I have no control over web statistics of GNS3 marketplace, it will help me to know how many people are using my labs, based on this information I would make more labs.
