aggregate6 will compress an unsorted list of IP prefixes (both IPv4 and IPv6).
Takes a list of IPv6 prefixes in conventional format on stdin, and
performs two optimisations to attempt to reduce the length of the prefix
list. The first optimisation is to remove any supplied prefixes which
are superfluous because they are already included in another supplied
prefix. For example, 2001:67c:208c:10::/64 would be removed if
2001:67c:208c::/48 was also supplied.
The second optimisation identifies adjacent prefixes that can be
combined under a single, shorter-length prefix. For example,
2001:67c:208c::/48 and 2001:67c:208d::/48 can be combined into
the single prefix 2001:67c:208c::/47.
The above optimalisation steps are often useful in context of compressing firewall rules or BGP prefix-list filters.
The following command line options are available:
::
-4 Only output IPv4 prefixes
-6 Only output IPv6 prefixes
-h, --help show help message and exit
-m N Sets the maximum prefix length for entries read, longer prefixes will be discarded prior to processing
-t truncate IP/mask to network/mask
-v Display verbose information about the optimisations
-V Display aggregate6 version
OpenBSD:
$ doas pkg_add aggregate6
CentOS/RHEL/Rocky:
| $ yum install epel-release
| $ yum install aggregate6
Fedora:
$ dnf install aggregate6
Other platforms:
$ pip3 install aggregate6
Either provide the list of IPv4 and IPv6 prefixes on STDIN, or give filenames containing lists of IPv4 and IPv6 prefixes as arguments.
::
$ # via STDIN $ cat file_with_list_of_prefixes | aggregate6 ... output ...
$ # with a filename as argument $ aggregate6 file_with_list_of_prefixes [ ... optional_other_prefix_lists ] ... output ...
$ # Whitespace separated works too $ echo 2001:67c:208c::/48 2000::/3 | aggregate6 2000::/3
$ # You can combine IPv4 and IPv6 $ echo 10.0.0.0/16 10.0.0.0/24 2000::/3 | aggregate6 10.0.0.0/16 2000::/3
Aggregate6 can be used in your own pyp/python2/python3 project as python
module. Currently there is just one simple public function:
aggregate() which takes a list as parameter.
::
from aggregate6 import aggregate aggregate(["10.0.0.0/8", "10.0.0.0/24"]) ['10.0.0.0/8']
