# What the scripts are used for
    * `/usr/local/sbin/update-irr-filters.sh` has to be put in a cron
    * `/usr/local/sbin/update-check-import.sh` is used to do generate the stuff
      common to all peers
    * `/usr/local/sbin/generate-irr-filter.sh` is used to generate each peer
      configuration

# Configuration files
`/usr/local/etc/bird-peers-update.conf` is sourced for three variables:
    * `PDB_API_KEY` which will be used to query the peeringdb api
    * `BIRD_CONF_PATH` for the base dir of bird (freebsd and linux have
      different ones)
    * `IXP_ASN` the ixp asn for the communities

# Override some peers configuration
If you want to add some configuration for some particular peers, you can do it
like that:
```
root@lillix-rs2:~# cat /usr/local/etc/bird-override/bgp_208627_ALARIG_193_34_197_135.conf
bfd on;
root@lillix-rs2:~# cat /usr/local/etc/bird-override/bgp_208627_ALARIG_2001_7f8_6d__20_8627_1.conf
bfd on;
```
