aggregate (optimise a list of route prefixes)
|
|
|
|
Takes a list of 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, 203.97.2.0/24 would be removed
|
|
if 203.97.0.0/17 was also supplied. The second optimisation
|
|
identifies adjacent prefixes that can be combined under a single,
|
|
shorter-length prefix. For example, 203.97.2.0/24 and 203.97.3.0/24
|
|
can be combined into the single prefix 203.97.2.0/23.
