# The meeting in Arago, Barcelona
![Guifi network](../Images/guifi-net.png)
This is the network graph of guifi.net. A wireless routed layer three network. **B.A.T.M.A.N.** [[1]](https://en.wikipedia.org/wiki/B.A.T.M.A.N.) routing protocol is active, but also **OSPF** [[2]](https://en.wikipedia.org/wiki/Open_Shortest_Path_First) and **BGP** [[3]](https://en.wikipedia.org/wiki/Border_Gateway_Protocol).
Like I've already said guifi is based upon Mikrotik. The stupid little purple bitch, a telecommunications entrepreneur in France, a daughter of military family in Italy, an hacker of systems and people in Spain and a terrorist in the world have used a public exploit to gain access in this free network. The problem is that this free network has got a **BGP autonomous system number** [[4]](https://www.inetdaemon.com/tutorials/internet/ip/routing/bgp/autonomous_system_number.shtml). The primary exchange ASN is **49835** [[5]](https://www.peeringdb.com/asn/49835), the data center is the **Catalunya neutral Internet exchange** [[6]](https://www.catnix.net/). In the same **IXP** [[7]](https://en.wikipedia.org/wiki/Internet_exchange_point) there is others very important connections:
- **Adamo** [[8]](http://www.adamo.es) **35699** [[9]](https://www.peeringdb.com/net/1989)
- **ESPANIX** [[10]](http://www.espanix.net)
- **Andorra Telecom** [[11]](
