CCIE Renewed - Exam 400-101

The problem with obtaining certifications is that you need to renew them. CCIE is no different - I first passed the lab in September 2012, and I was overdue for renewing it. I’m pleased to report that I have now done that, and it is now current until September 2016. Here’s some of my impressions of the 400-101 exam.

IPv6 availability in New Zealand

IPv6 has been around a fair while, and we’re constantly encouraged to learn it and use it. I agree with the sentiment, but it’s been hard for most users when few ISPs offer IPv6 for residential users. Hurricane Electric offers a great free IPv6 tunnel broker service, but that’s impractical for most people. What they need is for their ISP to offer native IPv6, by default.

NFD9 Prep: SD-WAN

Software Defined WAN, or SD-WAN, looks to be a theme of Network Field Day 9, with presenters such as CloudGenix and VeloCloud showing us their offerings. At first glance, SD-WAN sounds pretty compelling. Who wouldn’t want to slash their WAN OpEx? How do these solutions work, and do they have legs? I’m hoping to find out.

But now that many people have smartphones, tablets and laptops at home, their perception and understanding of technology has shifted. Old assumptions about training required when upgrading applications or client operating systems may no longer apply.

Headwinds, or Uphill?

As some of my readers know, I’ve done a fair bit of bike touring. Two of the challenges of bike touring are riding uphill, and riding into headwinds.

Resources for learning HP Comware

HP is making more resources available to help with learning Comware. They’ve added free labs and courses to the already published simulators and virtual routers. This is a good resource for those looking to get started with Comware.

Rate my IOS?

Review schemes are useful for identifying good consumer products and applications. But that doesn’t mean that everything needs to prompt me to leave a review. Cisco has started prompting for reviews for IOS versions, but I’m not convinced it makes sense for network operating systems. Perhaps it will do one day when disaggregated hardware/software is the norm for network devices.
