asn-tools's Introduction

asn-tools

A collection of scripts to automate BGP filter creation on a ubiquti EdgeOS (and VyOS/Vyatta).

In this repo included are:

confgen.rb - generates router configuration based on the config file

whoisgen.rb - generates import/export rules for the RIPE whois database.

filtergen.sh - generates import filters based on the IRRDBs (RADB,RIPE,ARIN)

The scripts were built with modularity in mind and so the templates are utilized to allow for easy extension.

Example config file

config:
  ouras: 31337
router:
  rtr1:
    model: vyatta
    upstream:
      42:

        ipv6:

          local-ip: 2000:1234::1

Generating rules

Usage script.rb [options]
    -r, --router=ROUTER              Router hostname
    -t, --type=TYPE                  Peer type
    -a, --as=AS                      AS Number
    -A, --all                        Generate configuration for all peeers
    -h, --help                       Display this screen

i.e. confgen.rb -t peering -a 666 -r rtr1
