Presentation abstract

In 2001, shortly after the IETF issued the IPv6 RFC, Cisco Systems provided for free an experimental version of the router software to the IPv6 community. This allowed interoperation testing over the 6bone. Where are we 10 years later?

Most deployed routers and switches are IPv6-capable at usually no increased cost as the IPv6 comes for free with IPv4. The absolute feature parity between IPv4 and IPv6 is mostly there but there remains some discrepancies that are being addressed before 2012. This mostly feature parity allows for easy IPv6 deployment on the technical side.

On the other hand, it was/is also complex for a network vendor to guess what its customers will deploy as transition models. All models have pros and cons but implementing all of them is costly for the manufacturer (hence prices are higher). This is especially applicable for residential home gateways when so little ISP offer IPv6 to the home users and where there are still a couple of uncertainties (such as the length of the allocated prefix).

On a more positive note, IPv6 is reaching many more products than routers and switches: IP phones, SAN, firewalls, VPN concentrators, anti-spam are all IPv6 ready. And of course, the Internet of Things heavily relies on IPv6.

Finally, it must be noted that all our SP customers are now fully aware of the IPv4-exhaustion issue and most of them are either running IPv6 in production or in pilot or intend to do it in 2011 (with a big exception for African SP). The interest for IPv6 has also reached our enterprise customers worldwide :-)


Eric graduated from the University of Liege, Belgium, in 1983 with a Master degree in Computer Science.

Since 1997, he works for Cisco as a Distinguished Engineer by helping customers with security designs and since 2007 with IPv6 deployments. He assists product design by advising engineering teams in Cisco. His area of expertise includes the security aspects of LAN switching, IP telephony and IPv6.

He is a guest professor at a couple of Belgian Universities (where he helped the IPv6 deployment), participates regularly at the IETF (author of RFC 3585 & 5514). He is also a respected speaker at several conferences such as RSA Conferences.

He is the main author of ‘LAN Switch Security’ and the co-author of ‘IPv6 Security’.
