aggregate6 takes a list of IPv4 and 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.
