Description

ASPA (AS Provider Authorization) is a new RPKI object type that AS holders can use to authorize their upstream providers in BGP. This allows providers to verify the paths they receive from customers and reject invalid AS paths. Furthermore, it helps to detect routing 'valleys' and reject such leaks.

This presentation focuses on the following:

  • Introduction into the ASPA verification algorithm
  • ASPA signing in the RIPE NCC RPKI Dashboard
  • ASPA validation in practice
  • Uptake and lessons learned so-far
Time Slot Restrictions n/a - I plan to come the day before and leave the day after.
