NAME
       aggregate-ios - optimise a concatenated set of cisco/IOS prefix filters
       to help make them nice and short.


SYNOPSIS
       aggregate-ios <source_config >optimised_config


DESCRIPTION
       Takes cisco IOS configuration on stdin, and optimises any prefix
       filters found using aggregate(1).  Optimised filters are produced on
       stdout.


OPTIONS
       None.


DIAGNOSTICS
       Any diagnostics produced by aggregate(1) are passed through on stderr.


EXAMPLES
       The following configuration fragment:

         ip prefix-list AS65530 description Foo, Inc
         ip prefix-list AS65530 permit 10.1.0.0/16
         ip prefix-list AS65530 permit 10.2.0.0/16
         ip prefix-list AS65530 permit 10.2.1.0/24
         ip prefix-list AS65530 permit 10.3.0.0/16
         ip prefix-list AS65531 description Bar.Com
         ip prefix-list AS65531 seq 5 permit 192.168.1.0/24
         ip prefix-list AS65531 seq 10 permit 192.168.2.0/24
         ip prefix-list AS65531 seq 15 permit 192.168.0.0/19

       is optimised as follows:

         ip prefix-list AS65530 permit 10.1.0.0/16 le 24
         ip prefix-list AS65530 permit 10.2.0.0/15 le 24
         ip prefix-list AS65531 permit 192.168.0.0/19 le 24
