An IPv6 is the sixth version of any IP address on the IP protocol. It consists of eight groups of four hexadecimal digits. IP v6 is a 128-bits address having an address space of 2^128.
For more details about IPv6 refer to the articles: What is IPv6? and Internet Protocol version 6 (IPv6) .
Steps to Configure IPv6 on Cisco Packets Tracer:
Step 1: First open the Cisco packet tracer desktop and create a network topology something like the image and an IPv6 addressing table given below.
IP Addressing Table:
Step 2: Configuring the GigabitEthernet Interfaces.
- First, we will configure the GigabitEthernet0/0 using CLI.
- Click on router0 and go to CLI and type the commands are given below:
- Now we will configure the GigabitEthernet0/1 Interface.
- Then, both the interfaces will be active now:
Step 3: Configuring Ipv6 address in both Interfaces using CLI:
- CLI commands to configure IPv6 address in GigabitEthernet0/0 and GigabitEthernet0/1 ports are given below:
Step 4: We have configured the router now change the settings of hosts in IPv6 configuration:
- First, click on PC0 and go to desktop then IP configuration.
- Now find the IPv6 configuration.
- Change the settings from static to automatic and then after a few seconds, the IPv6 address and default gateway are displayed.
- Similarly, repeat this procedure with PC1 and PC2
Step 5: Now we have to verify the connection by pinging the IPv6 address of PC0 in PC1.
- First, click on PC1 and go to the command prompt, and type ping <ipv6 address>
- As we can see in the below image, getting replies from PC0 means the connection is established successfully.

- IPv6 Configuration on Cisco Packet Tracer
Table of Contents
IPv6 is the new version of the most important Network Layer Protocol IP. With this new IP version, IPv6, beside different features, some configuration differencies are also coming. In this lesson, we will focus on these IPv6 Configuration Steps, IPv6 Configuration on Cisco devices . We will use the below Packet Tracer topology for our IPv6 Config .
You can download Packet Tracer IPv6 Lab , in Packet Tracer Labs page.
In this configuration lesson, we will follow the below IPv6 Configuration steps :
Enable IPv6 Globally
Enable ipv6 on interface, configure eui-64 format global unicast address, configure manual global unicast address, manual link local address configuration, auto ipv6 address configuration, enable dhcpv6 client, ipv6 verification commands.
So, let’s go to the IPv6 Configuration steps and configure IPv6 for Cisco routers .
After going to the configuration mode with “ configure terminal ” command, to enable IPv6 on a Cisco router, “ ipv6 unicast-routing ” command is used. With this Cisco command, IPv6 is enabled globally on the router. This can be used before both interface configurations and IPv6 Routing Protocol configurations.
Router 1# configure terminal Router 1(config)# ipv6 unicast-routing Router 2# configure terminal Router 2(config)# ipv6 unicast-routing
After enabling IPv6 globally, we should enable IPv6 under the Interfaces. To enable IPv6 under an interface, we will use “ ipv6 enable ” command. Let’s enable IPv6 on two interfaces of each router.
Router 1 (config)# interface FastEthernet0/0 Router 1 (config-if)# ipv6 enable Router 1 (config-if)# no shutdown Router 1 (config)# interface FastEthernet0/1 Router 1 (config-if)# ipv6 enable Router 1 (config-if)# no shutdown
Router 2 (config)# interface FastEthernet0/0 Router 2 (config-if)# ipv6 enable Router 2 (config-if)# no shutdown Router 2 (config)# interface FastEthernet0/1 Router 2 (config-if)# ipv6 enable Router 2 (config-if)# no shutdown
EUI-64 format is the IPv6 format used to create IPv6 Global Unicast Addresses . It is a specific format that we have also talked about before. With this format, basically, interface id of the whole IPv6 adderess is ceated with the help of the MAC address. After that, this created interface id is appended to the network id.
To configure an interface with EUI-64 format (Extended Unique Identifier), firstly we will go under the interface, then we will use “ ip address ipv6-address/prefix-length eui-64 ” command. Here, our IPv6 address and prefix-length are 2001:AAAA:BBBB:CCCC::/64. The real EUI-64 Global Unicast Address will be created with this address and MAC address after IPv6 configuration.
Router 1 (config)# interface FastEthernet0/0 Router 1(config-if)# ipv6 address 2001:AAAA:BBBB:CCCC::/64 eui-64 Router 1(config-if)# end
Let’s check the IPv6 address that is created with EUI-64 format with “ show ipv6 interface brief ” command.
Router 1# show ipv6 interface brief FastEthernet0/0 [up/up] FE80::2E0:B0FF:FE0E:7701 2001:AAAA:BBBB:CCCC:2E0:B0FF:FE0E:7701 FastEthernet0/1 [up/up] FE80::2E0:B0FF:FE0E:7702 Vlan1 [administratively down/down] unassigned
If we do not use EUI-64 format address, we have to write the whole IPv6 Address to the configuration line. Let’s configure Gigabit Ethernet 0/0 interface of Router 2 manually .
Router 2 (config)# interface FastEthernet0/0 Router 2 (config-if)# ipv6 address 2001:AAAA:BBBB:CCCC:1234:1234:1234:1234/64 Router 2(config-if)# end
Here, both of these directly connected interfaces are in the same subnet, the Network ID is same (2001:AAAA:BBBB:CCCC::/64).
Let’s check the IPv6 address that we have manually assigned with “ show ipv6 interface brief ” command.
Router 2# show ipv6 interface brief FastEthernet0/0 [up/up] FE80::206:2AFF:FE15:BD01 2001:AAAA:BBBB:CCCC:1234:1234:1234:1234 FastEthernet0/1 [administratively up/up] FE80::206:2AFF:FE15:BD02 Vlan1 [administratively down/down] unassigned
To check the connectivity between two node, we use ping. As IPv4, with IPv6, we also use ping, but this time it is called IPv6 Ping . The format of IPv6 Ping is a little difference than IPv4 Ping. These differences are the format of the used IP address and the used keywords. With IPv6 Ping , “ ping ipv6 ” keywords are used before the destination IPv6 address.
Here, we will ping from Router 1 GigabitEthernet0/0 interface to Router 2 GigabitEthernet0/0 interface.
Router 1# ping ipv6 2001:AAAA:BBBB:CCCC:1234:1234:1234:1234 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 2001:AAAA:BBBB:CCCC:1234:1234:1234:1234, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 0/0/1 ms
To check the configured IPv6 Address, we can use “ show ipv6 interface interface-name ” command.
Router 1# show ipv6 interface FastEthernet0/0 FastEthernet0/0 is up, line protocol is up IPv6 is enabled, link-local address is FE80::2E0:B0FF:FE0E:7701 No Virtual link-local address(es): Global unicast address(es): 2001:AAAA:BBBB:CCCC:2E0:B0FF:FE0E:7701 , subnet is 2001:AAAA:BBBB:CCCC::/64 [EUI] Joined group address(es): FF02::1 FF02::2 FF02::1:FF0E:7701 MTU is 1500 bytes ICMP error messages limited to one every 100 milliseconds ICMP redirects are enabled ICMP unreachables are sent ND DAD is enabled, number of DAD attempts: 1 ND reachable time is 30000 milliseconds ND advertised reachable time is 0 (unspecified) ND advertised retransmit interval is 0 (unspecified) ND router advertisements are sent every 200 seconds ND router advertisements live for 1800 seconds ND advertised default router preference is Medium Hosts use stateless autoconfig for addresses.
Router 2# show ipv6 interface FastEthernet0/0 FastEthernet0/0 is up, line protocol is up IPv6 is enabled, link-local address is FE80::206:2AFF:FE15:BD01 No Virtual link-local address(es): Global unicast address(es): 2001:AAAA:BBBB:CCCC:1234:1234:1234:1234 , subnet is 2001:AAAA:BBBB:CCCC::/64 Joined group address(es): FF02::1 FF02::2 FF02::1:FF15:BD01 FF02::1:FF34:1234 MTU is 1500 bytes ICMP error messages limited to one every 100 milliseconds ICMP redirects are enabled ICMP unreachables are sent ND DAD is enabled, number of DAD attempts: 1 ND reachable time is 30000 milliseconds ND advertised reachable time is 0 (unspecified) ND advertised retransmit interval is 0 (unspecified) ND router advertisements are sent every 200 seconds ND router advertisements live for 1800 seconds ND advertised default router preference is Medium Hosts use stateless autoconfig for addresses.
Here, with ipv6 ping, there are some options that we can use. These are given below:
ping ipv6 [hostname | ip_address] [repeat repeat-count | size datagram-size | source [ interface-name | source-address ]
- repeat : Ping packet count. The default ping repeat value is 5.
- size : Datagram size. The default value ping size is 56 bytes.
- source : Source Address of the ping. Default value is None.
So if we would like to send 10 IPv6 ping packet with 200 byte datagrams from 2001:AAAA:BBBB:CCCC:1234:1234:1234:1234 to 2001:AAAA:BBBB:CCCC:1111:2222:3333:4444, we will use the below command:
Router 2 # ping ipv6 2001:AAAA:BBBB:CCCC:1111:2222:3333:4444 repeat 10 size 200 source 2001:AAAA:BBBB:CCCC:1234:1234:1234:1234
To configure a Link Locak address manually, we use “ ipv6 address link-local ipv6-address ” command. Here, we should write an IPv6 address in the range of Link Local addresses. If you would like to learn more about a Link Local Address, you can check Link Local Address lesson.
Let’s configure GigabitEthernet0/1 interface of Router 1 with Link Local Address FE80::AAAA:BBBB:CCCC:DDDD. Here, there is no need to write a prefix length but we will add link-local keyword at the end of the command.
Router 1 (config)# interface FastEthernet0/1 Router 1 (config-if)# ipv6 address FE80::AAAA:BBBB:CCCC:DDDD link-local Router 1 (config-if)# end
Let’s check the manually configure ipv6 Link-Local address with “ show ipv6 interface brief ” command.
Router 1# show ipv6 interface brief FastEthernet0/0 [up/up] FE80::2E0:B0FF:FE0E:7701 2001:AAAA:BBBB:CCCC:2E0:B0FF:FE0E:7701 FastEthernet0/1 [administratively down/down] FE80::AAAA:BBBB:CCCC:DDDD Vlan1 [administratively down/down] unassigned
IPv6 Addresses can be configured automatically. This is one of the most important characteristics coming with IPv6. For IPv6 Auto configuration , we will use “ ipv6 address autoconfig ” command. Let’s use it on Router 2 on GigabitEthernet0/1.
Router 2 (config)# interface FastEthernet0/1 Router 2 (config-if)# ipv6 address autoconfig Router 2 (config-if)# end
This type of IPv6 address configuration is Sateless Auto Configuration .
Let’s check the Autoconfigured Link-Local ipv6 address with “ show ipv6 interface brief ” command.
Router 2# show ipv6 interface brief FastEthernet0/0 [up/up] FE80::206:2AFF:FE15:BD01 2001:AAAA:BBBB:CCCC:1234:1234:1234:1234 FastEthernet0/1 [up/down] FE80::206:2AFF:FE15:BD02 Vlan1 [administratively down/down] unassigned
Let’s ping from Router 2 to Router 1 to test this second interfaces’ ipv6 connection.
Router 2# ping ipv6 FE80::AAAA:BBBB:CCCC:DDDD Output Interface: FastEthernet0/1 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to FE80::AAAA:BBBB:CCCC:DDDD, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 0/0/1 ms
To enable DHCPv6 Client function on an interface, we use “ ipv6 address dhcp ” command under this interface. With this command, interface gets its IPv6 address form the DHCPv6 server . Let’s enable DHCPv6 on GigabitEthernet0/2 of Router 2.
Router 1 (config)# interface FastEthernet0/1 Router 1 (config-if)# ipv6 address dhcp Router 1 (config)# end
To verify DHCPv6 enabled interfaces, we can use “ show ipv6 dhcp interface ” command.
Router 1 # show ipv6 dhcp interface
To verify IPv6 Configuration, we can use different show commands. These IPv6 show commands are given below
- To check IPv6 interface configuration and status we use “ show ipv6 interface interface-id ”.
Router 1# show ipv6 interface FastEthernet0/0 FastEthernet0/0 is up, line protocol is up IPv6 is enabled, link-local address is FE80::2E0:B0FF:FE0E:7701 No Virtual link-local address(es): Global unicast address(es): 2001:AAAA:BBBB:CCCC:2E0:B0FF:FE0E:7701, subnet is 2001:AAAA:BBBB:CCCC::/64 [EUI] Joined group address(es): FF02::1 FF02::2 FF02::1:FF0E:7701 MTU is 1500 bytes ICMP error messages limited to one every 100 milliseconds ICMP redirects are enabled ICMP unreachables are sent ND DAD is enabled, number of DAD attempts: 1 ND reachable time is 30000 milliseconds ND advertised reachable time is 0 (unspecified) ND advertised retransmit interval is 0 (unspecified) ND router advertisements are sent every 200 seconds ND router advertisements live for 1800 seconds ND advertised default router preference is Medium Hosts use stateless autoconfig for addresses.
- To check IPv6 neighbor cache entries we use “ show ipv6 neighbors ”.
Router 1# show ipv6 neighbors IPv6 Address Age Link-layer Addr State Interface 2001:AAAA:BBBB:CCCC:1234:1234:1234:1234 23 0006.2A15.BD01 REACH Fa0/0 FE80::206:2AFF:FE15:BD02 7 0006.2A15.BD02 REACH Fa0/1
- To check IPv6 Routing Table we use “ show ipv6 route ”.
Router 1# show ipv6 route IPv6 Routing Table – 3 entries Codes: C – Connected, L – Local, S – Static, R – RIP, B – BGP U – Per-user Static route, M – MIPv6 I1 – ISIS L1, I2 – ISIS L2, IA – ISIS interarea, IS – ISIS summary O – OSPF intra, OI – OSPF inter, OE1 – OSPF ext 1, OE2 – OSPF ext 2 ON1 – OSPF NSSA ext 1, ON2 – OSPF NSSA ext 2 D – EIGRP, EX – EIGRP external C 2001:AAAA:BBBB:CCCC::/64 [0/0] via ::, FastEthernet0/0 L 2001:AAAA:BBBB:CCCC:2E0:B0FF:FE0E:7701/128 [0/0] via ::, FastEthernet0/0 L FF00::/8 [0/0] via ::, Null0
- To check IPv6 DHCP we use “ show ipv6 dhcp ”.
Router 1# show ipv6 dhcp This device’s DHCPv6 unique identifier (DUID): 0003000100E0B00E7701
- To check IPv6 Protocols we use “ show ipv6 protocols ”.
Router 1# show ipv6 protocols IPv6 Routing Protocol is “connected” IPv6 Routing Protocol is “static

How to Configure an IPV6 Interface on a Cisco Router
(UPDATE: We now have a video demo to accompany this post! Check it out on YouTube .)
Today, we'll take a look at how to configure an IPV6 address on a Cisco router. We'll use a Cisco ISR 1100 Series router but the configuration may be adjusted to work on any IOS XE device.
IPV6 is the future
Once you get a grasp on the fundamentals it's time to begin working on the CLI. We'll start with an interface config in today's post.
Enter configuration mode
First, we'll need to enter configuration mode on our ISR router.
How to enable IPv6
Next, we'll need to enable IPV6 routing on the top level. Without this line of config, the device won't route any IPV6 packets.
How to configure an IPV6 interface using EUI-64
We are now ready to configure the actual interface. Before we do that, recall a typical IPV4 configuration like the one below.
The IPV6 interface configuration will be very similar. Instead of using a subnet mask to specify the network portion of the address we'll use the prefix length notation.
The prefix length of an IPV6 address will almost always be 64.
You'll also notice that we didn't specify the last 64 bits of the address and instead added "eui-64". This config option allows the interface to automatically assign itself a unique 64-bit interface ID.
Check out the IEEE Standard to understand how EUI-64 assignment works.
How to verify our interface config
We may now verify that the interface address was correctly generated and assigned using the operational command below.
Here is a sample output of the desired result.
You'll notice that a Link-Local address has been assigned within the network FE80::/10 with the last 64 bits matching the interface ID of our global unicast address.
How to configure an IPV6 interface without using EUI-64
Another point we must highlight - the EUI-64 method of interface ID assignment is not mandatory of course. You can easily manually assign the full IPV6 address by omitting this option.
How to ping an IPv6 interface
Finally, if you want to ping the address you configured from an adjacent Cisco router you'll need to add the "ipv6" option into your ping command.
ULTRA CONFIG GENERATOR
You may download a template of the configuration discussed and import it into your Ultra Config Generator instance. We've also shown a screenshot of the template in action.

If you haven't heard of Ultra Config Generator, I would highly recommend you check it out. We designed the product to allow network engineers to generate and automate network configuration in a highly flexible, efficient and elegant manner. Our users love the application and I hope that you will too.
Take care until next time!

Manually Configuring IPv6 Addresses on an Interface
You want to manually configure a full IPv6 address on an interface.
You can configure an IPv6 unicast address on an interface by using a very similar process to how we set up IPv4 addresses in previous chapters of this book:
We can configure an IPv6 Anycast address by using the anycast keyword:
You can specify an IPv6 link-local address by using the link-local keyword:
In this recipe, we have manually configured three different types of IPv6 addresses. The first example simply configures a standard globally accessible unicast address. This is similar to the standard IPv4 unicast address:

Cisco Router IPv6 Configuration
At the beginning of the year 2011, we decided to apply the IPv6 configuration to our data center ( VeriTeknik ) and requested our IPv6 block from RIPE. RIRs give out /32 blocks to LIRs at the first assignment. This article describes basic Cisco IPv6 configuration.
The Preparation Steps
- Request your IPv6 Addresses from your RIR or LIR
- Add IPv6 Route to your AS number in LIR Portal
- Get your IPv6 VLAN IP from your Upstream Provider
- Configure your router
Configuring Cisco Routers for IPv6
Before you start applying IPv6 on your routers make sure that you backup your current configuration.
First of all, make a table of your arguments such as your IP addresses, AS numbers etc like below, we put some values for you to easily analyze the configuration:
Enable IPv6 & IPv6 CEF on your Cisco router:
Set your IPv6 address to the interface facing telco:
Don’t delete your IPv4 configuration or other necessary codes, just add
Switch to BGP configuration by typing “router bgp 65535”
type exit and type address-family ipv6 to enter IPv6 configuration
to announce your prefixes type:
Type exit one more and you need to add routes for your IPv6 addresses,
This is the basic IPv6 configuration for Cisco routers, now you should be able to communicate with IPv6 enabled hosts. To test your configuration you may assign IPv6 to one of your VLANs, an example given below:
