A lot of things have been added and improved since the last talk at DENOG10.

We want to take this opportunity to provide an update on what we have done on and what our agenda looks like.

This talk will present a scalable, redundant and vendor-neutral approach to provide firewalled network segments within an EVPN fabric.

Instead of stretching layer-2 segments, VRF route leaking is used to route traffic from network segments to the firewalls in a generic way. Using anycast gateways within the EVPN fabric, a consistent gateway behavior across firewalled and non-firewalled network segments is achieved.

In this talk, Pim will demonstrate high performance routing using open-source VPP and its underlying Data Plane Development Kit. This talk highlights the authors work on integrating the Linux Control Plane which makes BGP, OSPF, etc available with VPP, including smart ways to automate configuration of the router's data- and controlplane layers.

We’ll then turn to a popular DPDK based network load testing tool TRex, and discuss performance benchmarking results from the field using the author’s AS8298 as a practical example. This will demonstrate that a fully open source router can seriously compete with silicon based router vendors.

Route leaks containing more specific announcements of Internet Exchange Peering-LANs pose a risk to the reliability of Internet infrastructure.

RPKI validation and filtering can mitigate some of the dangers - if the IXP operator created proper ROAs.

In this lightning talk we will take a look at what can go wrong, how RPKI ROAs can save us and what the current state of the rollout is.

PeeringDB has been around for almost 20 years and is the go-to place for interconnection data. Whether to find new peers around you, looking for facilities when expanding your networks or retrieving configuration data for BGP sessions. PeeringDB has all of these data.

The database is a non-profit, community-driven initiative run and promoted by volunteers. It is a public tool for the growth and good of the Internet.

Due to the pandemic situation, we haven't updated the German community for a while. This presentation briefly introduces PeeringDB to bring newcomers up to speed and then roughly goes through the new features and developments

Pastel de Natas are delicious and while sharing some in Belgrade, the topic of "all traffic goes via Frankfurt" came up. So what does the traffic numbers actually say. And is the result something we should discuss?

There are very few troubleshooting tools that work across the public internet reasonably reliably. Well, it really boils down to Ping and Traceroute. Of those two, the latter is sometimes referred to as the "the number one go-to tool" for troubleshooting problems on the internet [1]. That is not, because it provides all the information we need or would like to have but at least, for the most part, it is universally supported. Traceroute is however missing one important piece of information, and that is information about the return path, i.e. the path from the target towards the host that initiated the traceroute. In this talk, we look at why this would be useful, what people have worked on in the past to implement a reverse traceroute tool and recent work in the IETF that aims at defining a standard protocol for reverse traceroute [2].

Are you hearing the word sustainability more and more often but you are not sure what exactly that means for you, your company, or the industry? In this talk you will learn about the new upcoming regulations, tracking options, network vendor sustainability data, reporting types and forms, organizational integration of sustainability data, as well as some certificates you can apply for. You'll also get insights into our lessons learned at Inter.link and our best practices to assist you on your sustainability journey.

DE-CIX has been working on the introduction of EVPN on its peering platform since the beginning of the year. Considering the increasing number of participants, especially in Frankfurt, the introduction of EVPN including ProxyARP/ND is already overdue in order to get the exponentially growing broadcast/multicast traffic in our peering LANs under control and to reduce the load on customer routers. Additionally further security features based on a ProxyARP/ND agent according to RFC 9161 will be activated and the protocol stack of our global network will be expanded to include RSVP-TE and sBFD. In this presentation we would like to present the course of the project, benefits and side effects for DE-CIX customers, explained in technical detail.

At the time of the potential presentation, we will already have migrated the first peering LANs and will be a few weeks in front of the DE-CIX Frankfurt migration.

Monitoring of traffic flows is a central aspect of modern network engineering from planning peering connectivity to anomaly detection. This talk discusses how we handle flows from different sources, enrich them with additional contextual data such as customer names or geo locations, and use that information in different contexts using our own Open Source [flowpipeline](https://github.com/bwNetFlow/flowpipeline) tool.

[BelWü (AS553)](https://www.belwue.de/) is the research and education network of the German federal state of Baden-Württemberg.
