This has been tested with the latest VyOS nightly 1.5-rolling-202403050022. First, I read the related VyOS blog post and the FRR docs. I really prefer learning while doing things instead of just reading the theory. Even though it means I will likely mess something up, that’s precisely what the Lab... VyOS 1.5, Segment Routing & GRE2024-01-01T18:00:00+01:00 2024-01-01T18:00:00+01:00 https://compumundohipermegared.one/posts/vyos-sr-gre-mpls-issue/ Fabrizzio Petrucci I was reading about Segment Routing, and I wanted to give that technology a try. I already had a GNS3 lab built with vSRX devices, with a basic IS-IS+LDP topology, running iBGP between PE routers and a L3VPN service. Unfortunately after trying to enable SR on the vSRX devices I found that you cannot configure SRGB on them. I’d have to re-do my lab with vMX and that’s not fun for me, it takes i... Adding LibreNMS graphs to my blog2023-11-05T19:00:00+01:00 2023-11-05T19:00:00+01:00 https://compumundohipermegared.one/posts/graph-page/ Fabrizzio Petrucci Over the weekend I had the idea to add a tab onto my blog, to show some of the statistics I collect within my network As I already run LibreNMS it was just a matter of creating a script on one of my Virtual Machines that will collect the graphs using LibreNMS API and then push them to my web server that runs Caddy. Pulling the graphs Here is (a simplified version) of the the main script grap... vSRX IPsec core dump using GNS32023-10-18T20:00:00+02:00 2023-10-18T20:00:00+02:00 https://compumundohipermegared.one/posts/vsrx-gns3-aes/ Fabrizzio Petrucci Some context Recently I’ve been studying for my JNCIA-SEC certificate, using the Juniper Open Learning portal & lessons. However I always set up the labs myself on my own kit. I got to the IPsec site to site VPN part of the course and I was happy enough to go onto my lab and put a couple vSRX instances each with a simulated internet connection and LAN, then create a tunnel between each ot... DNS records update via Ansible2023-07-02T13:00:00+02:00 2023-07-02T13:00:00+02:00 https://compumundohipermegared.one/posts/dns-update-ansible-01/ Fabrizzio Petrucci Laziness is King I already had a semi-automatic way of getting the AAAA and PTR records to put on my zonefiles, from the VyOS router configs. However it involved logging in manually to each router, pulling the config then pasting each one onto a script. Now, I (and StackOverflow and ChatGPT, of course) decided to quickly put together an Ansible playbook for it, along with a script for it. It’...
