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. |
