Exploring the blind spot of IXPs Route Servers
A study reveals that IRR-based filtering at IXPs can disconnect prefixes from their legitimate AS, allowing invalid announcements, and provides solutions.
MAIN POINTS
- IRR-based filtering at IXPs can lead to invalid prefix announcements.
- The study measures the impact of this issue across multiple IXPs.
- Invalid announcements occur when prefixes are disconnected from their legitimate AS.
- The research offers actionable solutions to address these filtering issues.
TAKEAWAYS
- IRR-based filtering can compromise the integrity of prefix-AS associations.
- Identifying the scale of the problem is crucial for IXPs.
- Implementing the study's solutions can enhance filtering accuracy.
- Awareness of filtering issues can lead to improved network security.
