generate access/prefix lists for BGP config
The bgpq3 utility can be used to generate prefix-lists and other types of filters for bgpd, BIRD, Cisco, Nokia SR-OS, Juniper Junos, and other BGP implementations. Bgpq3 retrieves its input from IRRd servers. Users of this might like to note that a fork, bgpq4 (which is faster and aims to be better), also exists and is in packages.
