✨ AGGREGATE-IOS(1) — General Commands Manual ✨

🎀 Manual name: aggregate-ios — okay so this tool is literally here to optimise a concatenated set of cisco/IOS prefix filters so they come out nice and short 💖

🌸 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

Okay bestie, this one is so iconic 👑 It takes cisco IOS configuration coming in on stdin and glows up any prefix filters it finds using aggregate(1). The optimised filters come out on stdout, no cap ✨

🫶 OPTIONS

None. 🙈 It's giving minimalism, fr fr 💜

💀 DIAGNOSTICS

Any diagnostics produced by aggregate(1) get passed straight through on stderr, so if something's up you'll still see it 🔥

🌈 EXAMPLES

The vibe is: you feed in this 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

...and it comes out totally optimised like this, main character energy 🦋✨

  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
