In a previous post I wrote that I started a gofundme to produce an IPv6 related tutorial series on YouTube, accompanied by blog posts, slides, labs and contributions to other projects like https://github.com/becarpenter/book6/
All videos will max. 20min, add free and I will reject any non relevant sponsoring.
Here are my ideas for the first 10 lessons (subject to change), not all off them strictly about IPv6, but also related topics like building your own lab, DNS, etc.
Based on another “IPv6 is bad” post on mastodon I diced it’s finally time:
Fund me to produce an IPv6 related tutorial series on YouTube, accompanied by blog posts, slides, labs and contributions to other projects, e.g. https://github.com/becarpenter/book6/
It’s been a while but I just update the IPv6-Resources list on gitlab.
If you want (or in my case have too) test some stuff with SLES and network equipment, you just can add a SLES container to your ContainerLab lab:
name: suse-lab
topology:
nodes:
suse:
image: registry.suse.com/suse/sle15:latest
kind: linux
One clab deploy later and you can access your SLES container:
root@clab:~/suse-lab# docker exec -ti clab-suse-suse bash
suse:/ # uname -a
Linux suse 6.1.0-40-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.153-1 (2025-09-20) x86_64 x86_64 x86_64 GNU/Linux
When you search the internet on how to use net-snmp with IPv6 most of the examples you’ll find look like this:
snmpwalk -v2c -c lab udp6:[3fff:172:20:20::5] | head -1
iso.3.6.1.2.1.1.1.0 = STRING: "Arista Networks EOS version 4.35.0F-44178984.4350F (engineering build) running on an Arista cEOSLab"
TIL: Apparently since version 5.7 you can just use
snmpwalk -v2c -c lab 3fff:172:20:20::5 | head -1
iso.3.6.1.2.1.1.1.0 = STRING: "Arista Networks EOS version 4.35.0F-44178984.4350F (engineering build) running on an Arista cEOSLab"
