Technical Workshop: A focus on ROAs and ASPAs, and how to handle them with Krill#

Peering Days 2026 digest Program Core pick 23–25 March 2026

Massimiliano Stucchi

  • Why: RPKI is mainstream; ASPA is the next routing-security primitive and directly addresses the class of route leaks that ROV cannot catch (path leaks) — the same gap the AS-SETs talk in this program quantifies. Hands-on delegated RPKI with Krill is adoptable tooling, not theory.
  • What: A refresher on RPKI and ROAs, an introduction to ASPAs (what they assert, how to create them, their role in global routing), and the bulk of the session is practical Krill setup for delegated RPKI, including preparing different publication setups. (from abstract only)
  • How: Workshop format: software setup and publication-architecture walkthroughs. (from abstract only)
  • Where applicable: Any operator running or considering delegated RPKI; vendor-neutral open-source tooling. The ASPA portion's practical payoff depends on how far ASPA verification has spread among your transits. No slides or paper were in the source material, so depth beyond the abstract is unknown.
