About:
bgpq4 is a tool that automatically generates prefix-lists and firewall filters for routers based on IRR data. It queries databases like RADB and RIPE to determine which IP prefixes are announced by specific AS numbers. This streamlines network security by ensuring routers only accept legitimate traffic from expected sources.
Key Features:
  • Supports Cisco, Juniper, BIRD, and OpenBGPD configurations
  • Queries multiple IRR databases (RIPE, RADB, etc.)
  • Generates prefix-lists and AS-path access lists
  • IPv4 and IPv6 address family support
Use Cases:
  • Generating BGP prefix filters for edge routers
  • Automating network security policy updates
  • Auditing announced IP prefixes for an AS number
Alternatives:
  • bgpq3 – bgpq4 is the modern successor with improved IPv6 support and active maintenance.
