Routing

Welcome to the routing working group session!

We supported GCA in their efforts to develop an elevated tier of MANRS (MANRS+) by conducting a feasibility study on measuring routing security controls. To this end, we developed a local prototype that simulates the audit of an AS using containerlab. We audit by setting up peering sessions between the audited AS and two other local ASes. The first AS exports prefixes to the audited AS and the second AS imports prefixes received from the audited AS. We then analyse the imported prefixes to draw…

We introduced ASPA concepts at RIPE 90. By RIPE 91 we will have enabled ASPA in the UI.

We would like to talk to the working group to once more share what ASPA is about for those who missed it, and then show how ASPA can be used in the RPKI Dashboard. We also want to ask for user feedback on the usability of the interface we built and plan to organise sessions for that on the Wednesday afternoon.

The BGP protocol is a crucial component of large network systems, particularly the Internet, as it enables Autonomous Systems (ASes) to exchange information about paths. Although it is essential, BGP is relatively fragile. Sometimes, software errors, misconfigurations, and malicious actors can cause disruptions that range from minor to severe, potentially leading to large-scale outages affecting popular services or companies. Despite efforts to enhance BGP security and configuration, further im…

"This 1 trick IP transit providers don't want you to know" - would be the title of this talk if it was a Substack blog post. Everyone is playing games to attract more traffic, one of those is to rewrite the BGP origin attribute, but it's not being talked about, so let's talk about it.

In this talk I will present how the largest carriers are rewriting the BGP origin attribute in order to attract more traffic to their network. It's nothing new, but anyone not doing this looses out. As an IP tran…
