BGPQ - программа для построения access и prefix-list'ов
(для оборудования Cisco
и фильтров для GateD'а.
Программа не призвана служить заменой RaToolSet'у, в связи с
ее гораздо большей тупизной :)
Compatibility: писано под FreeBSD,
проверенно и надежно работает под OpenBSD
работает под Linux, собирается, но не работает под Solaris.
Availablilty: доступно с
ftp://ftp.lexa.ru/pub/domestic/snar
Документация: при запуске без параметров
пишет о себе:
Usage: bgpq [-l name] [-h host] [-p port] [-d] [-Piosge]|[-f number]|[-F format] [-aq] [-S src] [-H] [-c] [-R masklen] objects [EXCEPT objects]
bgpq -r filename
-A - try to aggregate routes
-a - print all routes uncommented
-c - include commandline in output
-d - debugging
-e - generate standard access-list
-f - generate as-path access-list (number used as starting)
-F - generate output in given format
-g - generate GateD network filter
-H - do not print headers
-h - host with irrd (can be set with IRRD_HOST also)
-i - generate input packet filter
-l - name of generated access/prefixlist
-o - generate output packet filter
-P - generate prefixlist (access-list extended by default)
-p - irrd port (43 by default)
-q - print only aggreagated routes
-R - allow more specific routes up to masklen
-r - recreate file
-s - print statistics about
-S - use only specified source (can be set with IRRD_SOURCE)
"objects" means for networks (in prefix aka a.a.a.a/b format,
autonomous systems (in ASnnn format), as-macros (AS-xxxx format)
or rpsl filter (see RFC2622 or bgpq manpage for definition)
что, по моему скромному мению, понятно без дополнительных комментариев :)
Кроме того, в дистрибуте есть man-page, написанный на плохом английском.

Попытка сделать access-list гораздо более компактным:
- включаем аггрегацию и quiet-mode:
