After some questions in my previous blog post CLI-based analysis of an ExpressRoute private peering I decided to write an addition that includes what Expressroute Global Reach looks like for the CLI lover.

I have … Continue reading ExpressRoute Global Reach under the covers

I have been wanting to look into this for a while now, and I finally found a good excuse to do it. You might have read my series of posts on AKS networking, the goal of this is doing something similar with Azure Redhat Openshift (ARO). This is part 1 of a blog series around … Continue reading A day in the life of a packet in Azure Redhat Openshift (part 1)
I have to apologise because of skipping last month’s update, what has led to a massive update today.

Optionally, you … Continue reading What do Cisco ACI, microsegmentation, service insertion, REST and Docker containers have in common?
Do you have a network lab to try out new technologies? Then you might have experienced this problem: you finished testing technology A, and you start testing technology B. For that you need to reconfigure your devices, obviously. Now you need to try out something new in technology A, for example a new functionality brought … Continue reading Using NX-API to deploy full networks
Lately there seems to be a lot of buzz in the press about combining Cisco ACI and VMware NSX to achieve a comprehensive SDN solution.

First … Continue reading Are ACI and NSX complementary solutions?
