3 Enumerating Unnumbered

IPv4 addresses are getting expensive — to the point that you may not "throw it away" for infrastructure links that don't need them.

This presentation talkes a hands-on walk through the multiple ways of getting IPv4 routing without IPv4 addresses on router-to-router links:

• a short look at "historic" unnumbered serial PtP links
• classic IPv4-only unnumbered setups
• modern IPv4 with IPv6 nexthops (RFCs 5549/8950)
• known caveats, in particular while troubleshooting any of these setups

We'll be using FRRouting on Linux for configuration examples and demos, but everything is transferrable to other vendors (support for these setups is pretty common these days.)

Speaker: David 'equinox' Lamparter (NetDEF × FRRouting)

5 Building open source network monitoring solution with Netbox, Telegraf & Grafana

This presentation aims to shed light on open source approach for building high performance and highly scalable network monitoring solution, using the following tools:

Netbox: as source of truth. Netbox contains the devices and the corresponding hardware and software versions. This presentation shows also a way to use 'config context' feature for templating the configuration files for telegraf. Netbox feature of webhooks is used for notifying about the changes on the inventory.

Git: gitlab/github is used for version control of generated configuration files. Also Gitsync container is used for syncing the configuration files for telegraf instance.

Telegraf: is used for data collection with gNMI and SNMP. In certain cases data has to be normalized which is done with Starlark.

Timeseries database: Telegraf can expose the data to all common timeseries databases Prometheus/Influxdb/Mimir.

Grafana: is used for data visualization and alerting.

There will be also a demo of this setup.

7 A Quick Glance at the SRv6

In this presentation we will take a quick look at the relatively new Segment Routing over IPv6 technology. The presentation contains short introduction of SRv6 as a whole and then goes over the data and control plane mechanisms. SRv6 usage scenarios both for operator and customer will be discussed.

Presentation will be delivered by Aki Anttila, CTO, Reformo Networks. Aki has worked in the industry for almost 30 years as a trainer and consultant covering both enterprise and operator networks. Aki is M.Sc(EE) and holds CCIE*2 #25250 (SP, ENT) and JNCIE-ENT #406.

9 Upcoming nog.fi workshops

We are planning to organize technical "hands-on" workshops during the spring 2024.

I would like to get feedback from the audience on what type of topics should be covered there. I'll also present some ideas on which workshops I could host.
