BGP Workshop 4.0
2025-11-09 , Workshop 505

Want to perform the bgp handshake in real life based on a realistic topology? We got you covered ... in this workshop for intermediates we will dive into some network basics of bgp driven networks and also explore route filtering best practices (mainly for the DfZ = default free zone).

After some theory every attendee will receive one network node to configure. The fellow participants will be your peers. You will depend on the peers to reach your goals.

Teams work together in small groups. One group either jointly manages an AS consisting of 3 routers and a customer downlink router or the IXP infrastructure based on EVPN with additional route server. Troubleshooting takes place across groups in order to verify the corresponding availability within the lab topology.

Warning: You will have to socialise with the peers around you!

Topics Covered:
- Introduction into Internet/Routing Hierarchy
- Routing/Announcement Basics/Strategy
- Route Filtering
- Lab Introduction

Technologies Covered:
- TO BE DEFINED

Pre-requisites:
- Network Fundamentals, user level UNIX and maybe some system administration,
- Some use of network design preferably TCP/IP-based is also helpful.
- Dynamic routing Fundamentals (BGP, ISIS/OSPF is a plus)
- Participants must have technical hands on experience of routers.

Some experience with EOS or a comparable CLI will be helpful.


What should participants bring to the workshop?:

Notebook+SSH client

I’ve been a Network Engineer and Solution Architect through different positions and companies (Interoute/GTT/SysEleven/Inter.link). I've worked in small to very large projects, enterprises and networks. From simple to complex SDN driven (commercial or self build) to internet scale solutions. Main areas of expertise have been BGP (Routing, Policies etc.), MPLS/Traffic Engineering, DataCenter Fabric, Network Security (especially DDoS Detection and Mitigation) and overall network design and architecture. Besides that I also contribute to the Internet Community via the Berlin Internet Exchange (BCIX) as a member of the board. In 2024 I joined Arista Networks on my journey to build networks customers like the most.
