Wolfgang Tremmel
After completing his degree at Karlsruhe University, Wolfgang started working as a network engineer at Xlink in 1994. He went on to become head of network operations and peering manager at a range of ISPs.
In 2006, Wolfgang joined DE-CIX as Director Customer Support, a position he held for ten years. Since 2016, Wolfgang has been head of the DE-CIX Academy, making sure customers understand how BGP and other routing protocols work.
Sessions
Workshop about the basics of BGP. Topics include:
- Prefixes and Autonomous Systems
- Why you also need an IGP (like OSPF, IS-IS)
- iBGP: BGP within your network
- eBGP: Talking to your neighbours
- Multihoming and Peering
- BGP Best Path Selection
- Bonus-Topics, if time permits:
- BGP Communities
- BGP Security
Lab experiments will be done using FRRouting, so participants do need a laptop. No special software is needed.
The BGP Origin attribute has been around for decades and did not attract much attention. It is simply there, shown either as "?" for "incomplete" or as "i" for IGP.
During writing slides for my BGP training I found a large number (868) of prefixes in the global routing table tagged with "e" for EGP. The presentation does not give any answers but simply raises the question who and why is playing with that attribute.
