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

Would you like one of these very pretty logos on your webpage? Given my Irish passport I'm committed to having green as my favourite colour even if it doesn't work with my blue background, but alas, I'm not a graphic designer. The logo is assigned to invididual websites who are... Continue reading

For the past few months I've been battling away day after day, assuaging concerns about dynamic routing, layer 3 and newer technologies such as TRILL, OTV and Fabricpath. The mandate from above is straightforward and sensible: keep it simple. Good advice, but what exactly defines simple? Good Design versus a... Continue reading

After to speaking to Marin Levy, Director IPv6 Strategy at Hurricane Electric whilst attending the Norwegian chapter of the IPv6Forum's annual conference, I agreed to go through the Hurricane Electric IPv6 certification and compare and contrast it to IPv6 Forum's own certification.

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

I was recently tasked with improving a design for a branch office setup. The setup involves virtuals servers, virtual firewalls and virtual WAN accelerators.

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
