About:
bgpq3 is a command-line tool that automatically generates access control lists (ACLs) and prefix filters for routers. It queries IRR databases to extract network prefixes and AS numbers based on user-defined policies. This automation eliminates manual filter creation, reducing errors and ensuring accurate routing security.

Key Features:

Supports Cisco, Juniper, BIRD, and OpenBGPD configurations
Queries multiple IRR databases (RIPE, ARIN, APNIC, etc.)
Generates prefix-lists, as-path filters, and community filters
Supports both IPv4 and IPv6 prefix generation

Use Cases:

Automating BGP filter generation for network edge routers
Creating AS-SET based prefix filters for peering agreements
Auditing and validating existing router filter configurations

Alternatives:

irrd – IRRD is primarily an IRR database server, while bgpq3 is a client tool for generating filters from that data.
bird – BIRD is a routing daemon; bgpq3 is used to generate configuration filters for BIRD and other routers.
