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
