0.1.7 (2008-12-19):
- man page. Finally :)
- option -h now means not help, but now it can be used to point to
alternate IRRD host, like in old bgpq.
0.1.6 (2008-08-08):
- maxsockbuf call added, that can help with pipelining of really large
as-sets.

The

ultility used to generate Cisco and Juniper prefix-lists, extended
access-lists, policy-statements and as-path lists based on RADB data.
access-lists, policy-statement terms and as-path lists based on RADB data.
.Pp
The options are as follows:
.Bl -tag -width Ds
.It Fl 3
assume that your device is asn32-safe.
.It Fl 6
generate IPv6 prefix/access-lists (IPv4 by default).
.It Fl A
try to aggregate prefix-lists as much as possible (Cisco only).
.It Fl d
enable some debugging output.
.It Fl E
generate extended access-list (Cisco) or policy-statement term using
route-filters (Juniper).
.It Fl f Ar number
generate input as-path access-list.
.It Fl G Ar number
generate output as-path access-list.
.It Fl h
print usage information.
.It Fl J
generate config for Juniper (Cisco by default).
.It Fl M Ar match
extra match conditions for Juniper route-filters.
.It Fl l Ar name
name of generated entry.
.It Fl P
generate prefix-list (default, backward compatibility).
.It Fl R Ar len
allow specific routes up to specified masklen too.
.It Fl S Ar sources
use specified sources only (default: RADB,RIPE,APNIC).
.It Fl T
disable pipelining.
.It Ar OBJECTS
means networks (in prefix format), autonomous systems and as-macros.

Generating named juniper prefix-filter for AS20597:

policy-options {
replace:
prefix-list eltel {
81.9.0.0/20;
81.9.32.0/20;

217.170.80.0/20;
}
}

For Cisco we can use aggregation (-A) flag to make this prefix-filter
more compact:
.nf
.RS
~>bgpq3 -Al eltel AS20597
no ip prefix-list eltel
ip prefix-list eltel permit 81.9.0.0/20
ip prefix-list eltel permit 81.9.32.0/20
ip prefix-list eltel permit 81.9.96.0/20
ip prefix-list eltel permit 81.222.128.0/20
ip prefix-list eltel permit 81.222.192.0/18
ip prefix-list eltel permit 85.249.8.0/21
ip prefix-list eltel permit 85.249.224.0/19
ip prefix-list eltel permit 89.112.0.0/18 ge 19 le 19
ip prefix-list eltel permit 89.112.4.0/22
ip prefix-list eltel permit 89.112.64.0/19
ip prefix-list eltel permit 217.170.64.0/19 ge 20 le 20
.RE
.fi
- you see, prefixes 89.112.32.0/19 and 89.112.64.0/19 now aggregated
into single entry 89.112.0.0/18 ge 19 le 19.
.Lp
Well, for Juniper we can generate even more interesting policy-options,
using -M <extra match conditions>, -R <len> and hierarchical names:
.nf
.RS
~>bgpq3 -AJEl eltel/specifics -R 32 -M "community blackhole" AS20597
policy-options {
policy-statement eltel {
term specifics {
replace:
from {
community blackhole;
route-filter 81.9.0.0/20 upto /32;
route-filter 81.9.32.0/20 upto /32;
route-filter 81.9.96.0/20 upto /32;
route-filter 81.222.128.0/20 upto /32;
route-filter 81.222.192.0/18 upto /32;
route-filter 85.249.8.0/21 upto /32;
route-filter 85.249.224.0/19 upto /32;
route-filter 89.112.0.0/18 prefix-length-range /19-/32;
route-filter 89.112.64.0/19 upto /32;
route-filter 217.170.64.0/19 prefix-length-range /20-/32;
}
}
}
}
.RE
.fi
generated policy-option term now allows all specifics for eltel networks
if they match with special community 'blackhole'.
.Lp
Of course, this version supports IPv6 (-6):
.nf
.RS
~>bgpq3 -6l as-retn-6 AS-RETN6
no ipv6 prefix-list as-retn-6
ipv6 prefix-list as-retn-6 permit 2001:7fb:fe00::/48
ipv6 prefix-list as-retn-6 permit 2001:7fb:fe01::/48
[....]
.RE
.fi
and initial support for ASN 32 is also here (however, now only for
Juniper JunOS 9.1+ - Cisco IOS is not (as of yet) supports it):
.nf
.RS
~>bgpq3 -J3f 112 AS-SPACENET
policy-options {
replace:
as-path-group NN {
as-path a0 "^112(112)*$";
as-path a1 "^112(.)*(1898|5539|8495|8763|8878|12136|12931|15909)$";
as-path a2 "^112(.)*(21358|23456|23600|24151|25152|31529|34127|34906)$";
as-path a3 "^112(.)*(35052|41720|43628|44450|196611)$";
}
}
.RE
.fi
see AS196611 in the end of the list ? That's AS3.3 in 'asplain' notation.
.Lp
For Cisco and old versions of JunOS you should not use switch -3,
and the result will be next:
.nf
.RS
~>bgpq3 -f 112 AS-SPACENET
no ip as-path access-list NN
ip as-path access-list NN permit ^112(_112)*$
ip as-path access-list NN permit ^112(_[0-9]+)*_(1898|5539|8495|8763)$
ip as-path access-list NN permit ^112(_[0-9]+)*_(8878|12136|12931|15909)$
ip as-path access-list NN permit ^112(_[0-9]+)*_(21358|23456|23600|24151)$
ip as-path access-list NN permit ^112(_[0-9]+)*_(25152|31529|34127|34906)$
ip as-path access-list NN permit ^112(_[0-9]+)*_(35052|41720|43628|44450)$
.RE
.fi
.Lp
AS196611 is no more in the list, however, AS23456 (transition AS)
would be added to list if it were not present.
.Sh DIAGNOSTICS
When everyting is ok,
.Nm
generates access-list to standard output and exits with status == 0.
In case of errors they are printed to stderr and program exits with
non-zero status.
