En sembla que ja comencen a veure la llum amb el tema de les àrees, sobretot gràcies a la col·laboració de Miquel Martos i en Pere Franquesa. Fa molts dies que estem fent proves, jo tenia fins ahir tres ràdios que simulaven el AP1 http://guifi.net/guifi/device/789 i l'enllaç cap Vinyoles http://guifi.net/guifi/device/788 des de Torelló i el VinyolesTorelló http://guifi.net/guifi/device/799 i al final comença a tenir alguna lògica.

Us passo les configuracions dels OSPF per muntar l'àrea 1 a la zona de Torelló (és una simulació i no correspon al 100% al que hi ha a la base de dades de guifi.net), intentaré en breu posar-ho en marxa sobre el supernode de TorelloDipSud.
