Well, after a lot of umming and ahhing, I finally decided to put my head down for two weeks and got my CCNP SWITCH and CCNP TSHOOT done. That on top of my already passed CCNP ROUTE has achieved me a CCNP Routing and Switching from Cisco. If you're contemplating... Continue reading

I had a wee job to do for a friend last week. It was simple enough: add HSRP to four Nexus 5548 boxes on several of the SVIs. Well, for the life of me I couldn't get it to work properly. Routers couldn't find their standby routers, failover was slow,... Continue reading

A big thanks to the folks at Hurricane Electric and their IPv6 Certification Program for their certification and also this delightful white T-Shirt that a few of us in Oslo will be sporting around the parks (for the sporty ones) or around the bars ( I can think of a... Continue reading

I've started studying for my CCIE Data Centre with a bunch of lads in Oslo, Norway. This week and next, we're taking a deep dive into the UCS for the written exam. If you are like me in the sense that a UCS is a tad on the expensive side,... Continue reading

What They Are Hurricane Electric The Hurricane Electric... Continue reading

Right, well it seems I'm now a guru. Jolly good. The thing is however, I have always wanted to be a sage. We've set up IPv6 mail servers ( I couldn't get Google to change their policies so I changed my MX record and watched the bytes on the wire),... Continue reading

The problem that was being seen was two fold; A layer 2 connection from the WAN Router to the Firewall. This meant that if the firewall... Continue reading

I'm sitting here in the middle of the night (it's now 06:22) waiting for a provider to do some routing in their network to route some traffic over a satellite link. So I thought I might briefly reflect on a Fabricpath test I did this week with four Cisco Nexus... Continue reading

On the 5th April, 2012 I received an E-Mail from the IPv6 Forum informing me that my application for the IPv6 Silver Certified Engineer was successful. This means that I am free to use the logo on the left on my website, blog, publications etc. It also means that the... Continue reading
