ipcalc #ansible filter – manage floating ip ranges for packet.net

Post based on https://github.com/digineo/ansible-ipcalc I’ve been working many times with floating IPs for my SDWAN demos and deployments. It’s been some kind of annoying to change the configuration files so many times. Figure what IPs I should assigned to every server depending on the segment and netmask that packet gave me. Those changes also, are prone to typos that waste precious time. On this post … Continue reading ipcalc #ansible filter – manage floating ip ranges for packet.net

Happy 2018, and by the way, SDWAN is growing bad…

I’ve been working more than two years in Nuage Networks traveling all around Americas (North, Central and South. And BTW, Mexicans are North-Americans. Please, don’t tell me otherwise. ok? ). Now, we have SDWAN initiatives thru Local Operators, Service Providers and Startups all over.

SDN/SDWAN lab on-premises within 60min #Nuage

Create your SDWAN lab on-premises with ansible is a nicer experience. I have this new playbook that will help you. So far, it works on just one KVM host. Nuage instances will be accessed via ssh using other KVM Host’s ports with DNAT (iptables). Just check the “hosts” inventory file after build it. We’ll do the following: * yum update of your KVM host * … Continue reading SDN/SDWAN lab on-premises within 60min #Nuage

Windows 2012R2 on KVM

Not a fan. Some app requires windows though. I want to stay with KVM on Centos. Then @hballesteros and I figured (after some saint google search) to install windows loading the virtio drives from a cdrom iso over the setup process. 1. First of all you need to have the iso media (cdrom) and download it at your KVM (i.e. evaluation version at https://www.microsoft.com/en-US/evalcenter/evaluate-windows-server-2012-r2). Rename … Continue reading Windows 2012R2 on KVM

Multi-Host Networking using Consul, Docker Libnetwork and Nuage SDN
