Objectives
- Part 1: Build the Network and Configure Basic Device Settings
- Part 2: Verify SLAAC address assignment from R1
- Part 3: Configure and verify a Stateless DHCPv6 Server on R1
- Part 4: Configure and verify a Stateful DHCPv6 Server on R1
- Part 5: Configure and verify a DHCPv6 Relay on R2
Background / Scenario
The dynamic assignment of IPv6 global unicast addresses (GUA) can be configured the following three ways:
- Stateless Address Auoconfiguration (SLACC)
- Stateless Dynamic Host Configuration Protocol for IPv6 (DHCPv6)
- Stateful DHCPv6
When using SLACC to assign IPv6 addresses to hosts a DHCPv6 server is not used. Because a DHCPv6 server is not used when implementing SLACC, hosts are unable to receive additional critical network information, including a domain name server (DNS) address as well as a domain name.
When using Stateless DHCPv6 to assign IPv6 addresses to host, a DHCPv6 server is used to assign the additional critical network information, however the IPv6 address is assigned using SLACC.
When implementing Stateful DHCPv6, a DHCPv6 server assigns all network information, including the IPv6 address.
The determination of how hosts obtain they dynamic IPv6 addressing is dependent on flag setting contain within the router advertisement (RA) messages.
In this scenario, the company has grown in size, and the network administrators can no longer assign IP addresses to devices manually. Your job is to configure the R2 router to assign IPv6 addresses on two different subnets connected to router R1.
Note: The routers used with CCNA hands-on labs are Cisco 4221 with Cisco IOS XE Release 16.9.4 (universalk9 image). The switches used in the labs are Cisco Catalyst 2960s with Cisco IOS Release 15.2(2) (lanbasek9 image). Other routers, switches, and Cisco IOS versions can be used. Depending on the model and Cisco IOS version, the commands available and the output produced might vary from what is shown in the labs. Refer to the Router Interface Summary Table at the end of the lab for the correct interface identifiers.
Note: Ensure that the routers and switches have been erased and have no startup configurations. If you are unsure contact your instructor.
Instructor Note: Refer to the Instructor Lab Manual for the procedures to initialize and reload devices

In Part 1, you will set up the network topology and configure basic settings on the PC hosts and switches.
Step 1: Cable the network as shown in the topology.
Attach the devices as shown in the topology diagram, and cable as necessary.
Step 2: Configure basic settings for each switch. (Optional)
a. Assign a device name to the switch.
switch(config)# hostname S1 switch(config)# hostname S2
b. Disable DNS lookup to prevent the router from attempting to translate incorrectly entered commands as though they were host names.
S1(config)# no ip domain-lookup S2(config)# no ip domain-lookup
c. Assign class as the privileged EXEC encrypted password.
S1(config)# enable secret class S2(config)# enable secret class

Step 3: Configure basic settings for each router.
a. Assign a device name to the router.
router(config)# hostname R1 router(config)# hostname R2
b. Disable DNS lookup to prevent the router from attempting to translate incorrectly entered commands as though they were host names.
R1(config)# no ip domain-lookup R2(config)# no ip domain-lookup
c. Assign class as the privileged EXEC encrypted password.
R1(config)# enable secret class R2(config)# enable secret class

g. Create a banner that warns anyone accessing the device that unauthorized access is prohibited.
R1(config)# banner motd $ Authorized Users Only! $ R2(config)# banner motd $ Authorized Users Only! $
h. Enable IPv6 Routing
R1(config)# ipv6 unicast-routing R2(config)# ipv6 unicast-routing
i. Save the running configuration to the startup configuration file.
R1(config)# exit R1# copy running-config startup-config R2(config)# exit R2# copy running-config startup-config
Step 4: Configure interfaces and routing for both routers.
a. Configure the G0/0/0 and G0/0/1 interfaces on R1 and R2 with the IPv6 addresses specified in the table above.
R1(config)# interface g0/0/1 R1(config-if)# ipv6 address fe80::1 link-local R1(config-if)# ipv6 address 2001:db8:acad:1::1/64 R1(config-if)# no shutdown R1(config)# interface g0/0/0 R1(config-if)# ipv6 address fe80::1 link-local R1(config-if)# ipv6 address 2001:db8:acad:2::1/64 R1(config-if)# no shutdown R2(config)# interface g0/0/1 R2(config-if)# ipv6 address fe80::1 link-local R2(config-if)# ipv6 address 2001:db8:acad:3::1/64 R2(config-if)# no shutdown R2(config)# interface g0/0/0 R2(config-if)# ipv6 address fe80::2 link-local R2(config-if)# ipv6 address 2001:db8:acad:2::2/64 R2(config-if)# no shutdown
b. Configure a default route on each router pointed to the IP address of G0/0/0 on the other router.
R1(config)# ipv6 route ::/0 2001:db8:acad:2::2 R2(config)# ipv6 route ::/0 2001:db8:acad:2::1
c. Verify routing is working by pinging R2’s G0/0/1 address from R1
R1#(config)# exit R1# ping 2001:db8:acad:3::1
d. Save the running configuration to the startup configuration file.
R1# copy running-config startup-config
Part 2: Verify SLAAC Address Assignment from R1
In Part 2, you will verify that Host PC-A receives an IPv6 address using the SLAAC method.
Power PC-A up and ensure that the NIC is configured for IPv6 automatic configuration.
After a few moments, the results of the command ipconfig should show that PC-A has assigned itself an address from the 2001:db8:1::/64 network.

Where did the host-id portion of the address come from?
Answer will depend upon the operating system configuration. Either the host generates an EUI-64 address based on the interface MAC, or the host generates a random 64-bit address.
Part 3: Configure and Verify a DHCPv6 server on R1
In Part 3, you will configure and verify a stateless DHCP server on R1. The objective is to provide PC-A with DNS server and Domain information.
Step 1: Examine the configuration of PC-A in more detail.
a. Issue the command ipconfig /all on PC-A and take a look at the output.

b. Notice that there is no Primary DNS suffix. Also note that the DNS server addresses provided are “site local anycast” addresses, and not unicast addresses, as would be expected.
Step 2: Configure R1 to provide stateless DHCPv6 for PC-A.
a. Create an IPv6 DHCP pool on R1 named R1-STATELESS. As a part of that pool, assign the DNS server address as 2001:db8:acad::1 and the domain name as stateless.com.
R1(config)# ipv6 dhcp pool R1-STATELESS R1(config-dhcp)# dns-server 2001:db8:acad::254 R1(config-dhcp)# domain-name STATELESS.com
b. Configure the G0/0/1 interface on R1 to provide the OTHER config flag to the R1 LAN, and specify the DHCP pool you just created as the DHCP resource for this interface.
R1(config)# interface g0/0/1 R1(config-if)# ipv6 nd other-config-flag R1(config-if)# ipv6 dhcp server R1-STATELESS
c. Save the running configuration to the startup configuration file.
R1# copy running-config startup-config
d. Restart PC-A.
e. Examine the output of ipconfig /all and notice the changes.

f. Test connectivity by pinging R2’s G0/0/1 interface IP address.
Part 4: Configure a stateful DHCPv6 server on R1
In Part 4, you will configure R1 to respond to DHCPv6 requests from the LAN on R2.
a. Create a DHCPv6 pool on R1 for the 2001:db8:acad:3:aaaa::/80 network. This will provide addresses to the LAN connected to interface G0/0/1 on R2. As a part of the pool, set the DNS server to 2001:db8:acad::254, and set the domain name to STATEFUL.com.
R1(config)# ipv6 dhcp pool R2-STATEFUL R1(config-dhcp)# address prefix 2001:db8:acad:3:aaa::/80 R1(config-dhcp)# dns-server 2001:db8:acad::254 R1(config-dhcp)# domain-name STATEFUL.com
b. Assign the DHCPv6 pool you just created to interface g0/0/0 on R1.
R1(config)# interface g0/0/0 R1(config-if)# ipv6 dhcp server R2-STATEFUL
Part 5: Configure and verify DHCPv6 relay on R2.
In Part 5, you will configure and verify DHCPv6 relay on R2, allowing PC-B to receive an IPv6 Address.
Step 1: Power on PC-B and examine the SLAAC address that it generates.

Notice in the output that the prefix used is 2001:db8:acad:3::
Step 2: Configure R2 as a DHCP relay agent for the LAN on G0/0/1.
a. Configure the ipv6 dhcp relay command on R2 interface G0/0/1, specifying the destination address of the G0/0/0 interface on R1. Also configure the managed-config-flag command.
R2(config)# interface g0/0/1 R2(config-if)# ipv6 nd managed-config-flag R2(config-if)# ipv6 dhcp relay destination 2001:db8:acad:2::1 g0/0/0
The Packet Tracer software doesn’t support all IOS commands and features.
b. Save your configuration.
R2# wr
Step 3: Attempt to acquire an IPv6 address from DHCPv6 on PC-B.
a. Restart PC-B.
b. Open a command prompt on PC-B and issue the command ipconfig /all and examine the output to see the results of the DHCPv6 relay operation.
