Peering into BGP

The BGP communities attribute, which usefully enables network operators to signal specific requests or information to nearby ASNs, also lets them signal RPKI status. But should they? In this presentation, I show the results of investigating the propagation of RPKI information in BGP communities.

There is a baseline of BGP Updates that is derived from the updates in RPKI - the creation or deletion of ROAs/VRPs - and this presentation shows what it is, who does it, and why this is not good for the Internet.

This presentation is also related to work being done at the IETF to propose a new BCOP document to help operators understand how the behaviour of propagating RPKI information in BGP Communities is not good for the Internet.
