The topic of IPv6 is not new in the industry. In fact, IPv6 has been hotter now than ever, particularly around IPv4 address exhaustion and application readiness. Cisco’s Tony Hain is an IPv6 Forum Fellow. Cisco IPv6 product manager and evangelist, Patrick Grossetet has been driving IPv6 development at Cisco.Geoff Huston, Chief Scientist APNIC has been exploring IPv6 transit.In fact, this past January 2008, Google held an IPv6 summit whe…

The US Federal Government, like many large IT organizations  and other national governments recognizes the important of transition their networks to support IPv6. On Sept 2010 a memo on the transition to IPv6, was issued by then Federal CIO; Vivek Kundra, outlining the government’s commitment and rational behind expediting the operational deployment and use of IPv6. The memo set two goals, the first being for all Federal agencies to try and upgr…

Today, many organizations are focusing on how to integrate IPv6 services into their Internet edge. The World IPv6 Launch has come and gone with over 3000 sites now IPv6-enabled.  In addition, the US government has directed that all agencies must enable their Internet facing services for IPv6 by October 1st, 2012. These drivers are pushing organizations to take a harder look at how to approach IPv6 integration.  My next couple of posts will exami…

In the previous installment of our series of IPv6 posts, we covered some common myths regarding IPv6. In this post, we’ll talk about how the role of ICMP has changed in IPv6 compared to IPv4. In IPv4, ICMP provides error reporting, flow control and first-hop gateway redirection. This functionality, which is also available in IPv6, is usually not essential to the operation of your network. With IPv6, however, ICMP has gained a much more sig…

Now that the Internet community is done officially launching IPv6 (World IPv6 Launch) on June 6th, it is about time to seriously think about the co-existence of IPv6 and MPLS (i.e. MPLSv6) without relying on IPv4 for any control plane functionality. Is it possible now? Well, yes (though the mileage may vary). Does it matter? Oh, absolutely yes. MPLSv6 is about MPLS forwarding of IPv6 packets. It has existed since 2005 in form of 6PE [RFC4798] an…
