BGPQ

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] [-aq] [-S src] [-H] [-c] objects [EXCEPT objects]
	-A - try to aggregate routes
	-a - print all routes uncommented
	-c - include commandline in output
	-d - debugging
	-e - generate standard access-list
	-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
	-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.

Простейшая генерация access-list'а:

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