# [Gitoyen](http://www.gitoyen.net/): BIRD configuration for a border router

This repository contains the configuration for one of Gitoyen's border router. Configurations is made of:

  * BGP communities management;
  * Traffic delivery (members, clients) management;
  * Peering & transit management.

Feel free to take inspiration from it.

## Some principles

* Routes imported from a BGP session are tagged with a community according to the BGP peer.
* Routes exported to a BGP session are filtered using communities based on the BGP peer.
  * Examples:
    * Routes exported to a transit operator session only contain properly tagged ones (members/clients/internal).
    * Routes exported to a member session are all Internet routes (full-view).
