Notes
This tool uses MRT dumps from the dn42 Global Route Collector (GRC).
- Blue: selected source ASN
- Green: origin ASN, passing ROA
- Red: origin ASN, failing ROA
- Solid line: this adjacency is known to exist from GRC paths
- Dashed line: guessed path; source ASN has no route to this prefix visible to the GRC
