That should be an indication to everyone that IPv6 is being implemented around the globe because Cisco wouldn’t go through all this trouble of writing all this code if there wasn’t customer demand.

IPv6 Source Specific Multicast (SSM) Mapping.

Some of the newest IPv6 features include: Because I was finishing up my book on IPv6 Security at that time I haven’t had a chance to test many of these features but they look interesting. This new IOS version was released in the latter months of 2008. There are also new IPv6 features in the recent IOS release 12.4(22)T.

IPv6 support within the VPN Services Port Adapter (VSPA).

6VPE support (IPv6 VPN Provider Edge routing) (RFC 4659).

Multicast address group range support for IPv4 and IPv6.

IPv6 is mentioned so many times in this document it is hard to count. There is also a presentation that goes with this that covers the new features and enhancements in this new IOS version for 6500 switches. IPv6 will now appear within the IP Services feature set.

This document confirms the good news that IPv6 will start coming standard in IOS versions in the future.

If you look at the November 2008 Cisco IOS Software Collateral Library you will find information about new Features in Cisco IOS 12.2(33)SXI. This parity will be extended to other platforms in the future.” However, if you read the fine print you will see that Cisco has several asterisks next to IPv6 that indicate that “Starting with 12.2(33)SXI on the 6500 series, Cisco is offering packaging parity for IPv6 with IPv4 such that IPv6 feature support for a technology will be packets in the same feature set as IPv4.

Many Cisco customers have complained in the past about having to upgrade their IOS from IP Base to Advanced IP Services just to receive IPv6 functionality. As you can see, IPv6 is contained in Advanced IP Services. There is a document here on Cisco IOS Packaging Product Bulletin PB2855 and it covers what types of features are in what IOS feature sets.

If you look at the December 2008 library you will find that there are some new IOS feature documents. I have learned a lot from this site over the past few years. You can look through documents by-engineers, for-engineers, on the latest whiz-bang nerd knobs for propeller heads. There are many golden nuggets of information in this part of Cisco’s web site. If you have never browsed through this great set of documents, I encourage you to do so. One great place that I like to look for new IOS feature information is the Cisco IOS Software Collateral Library. I guess I am one of those weirdoes who like looking for new features in the latest IOS images. I got in the habit of reading these when I was studying for my CCIE as I wanted to anticipate what they might throw at my on the lab. I recognize that not many people sit around and look at release notes for Cisco IOS anymore. Recently I was reading some Cisco IOS release notes and I have noticed a lot more frequent mention of new IPv6 features. I am realizing that more and more IPv6 functionality is being developed and integrated into the latest versions. Last step is to enable it on the interfaces with the ipv6 eigrp command.I wanted to share with you something that I have observed in the recent release notes for some of the newest Cisco IOS versions. By default, the EIGRP process is in shutdown mode and you need to type no shutdown to activate it. If you don’t have any IPv4 addresses you need to specify it yourself with the router-id command. Each EIGRP router needs a router ID which is the highest IPv4 address on the router. The number you see is the autonomous system number and it has to match on both routers. R2(config)# interface GigabitEthernet 0/1įirst, you need to start EIGRP with the ipv6 router eigrp command. R1(config-if)# ipv6 eigrp 1 R2(config)# ipv6 router eigrp 1 R1(config)# interface GigabitEthernet 0/1 This is how you enable EIGRP for IPv6: R1(config)# ipv6 router eigrp 1 Let’s verify our work: R1# show ipv6 interface briefĪfter configuring the IPv6 addresses on the loopback interface you can see the global unicast and the link-local IPv6 addresses. The loopback interfaces will have a global unicast address. R1(config-if)# ipv6 address 2001::1/128 R2(config)# interface loopback 0Įnabling IPv6 on the Gigabit interfaces will generate an IPv6 link local address. (config-if)# ipv6 enable R1(config)# interface loopback 0 Configurationįirst we will enable routing for IPv6: R1 & R2Īnd let’s configure some IPv6 addresses: R1 & R2 Note that I don’t have any global unicast IPv6 addresses on the FastEthernet interface because the EIGRP updates will be sent using the link-local addresses.

Configuration is a bit different and in this lesson I’ll demonstrate to you how to configure it. Cisco’s EIGRP is one of the routing protocols that is suitable for IPv6.
