Resolución de problemas

Sebastian Galeano:
Si te fijas con el torch, mira si en la rb salen los OSPF-hellos cada 10segundos hacia broadcast, después mira en el otro a ver si llegan, hay cierto problema con versiones del AirOS V y dependiendo del modo de funcionamiento se filtra el broadcast/multicast.

Xavi Caballé: No soy un experto en OSPF, ni mucho menos, pero según tengo entendido, los routers de una misma área intercambian los LSA's. Cuando todos los routers de una misma área tienen las mismas LSA's se crean las rutas dinámicas. Si dos routers no forman parte de la misma área o las LSA's no son las mismas en ambos, puede que las vean pero no pasen a ser rutas activas
Por tanto creo que la clave podría estar en el tema de las áreas, comprobar que todas estén bien definidas como backbone en todas las interficies y redes. También comprobar que ambos routers tengan las mismas LSA's en las tablas; es posible que reciban las LSA's y que por ello aparezcan las rutas, pero si no coinciden las LSA's en los dos routers, las rutas no se activan.
Aportación de Pablo Boronat:
Nosotros tenemos varios nodos funcionando así. Alguno nos está dando problemas con el OSPF. No sabemos por qué ya que hay momentos en los que funciona. Pensamos que es porque hay diferentes versiones en routeros, openwrt y airos, pero no estamos seguros. La mayoría funcionan perfectamente. En las antenas ubiquiti tienes modo bridge y una 172. Nosotros ponemos una pública 10. para poder entrar a configurarla por web sin hacer nada más. La 172 la tiene el mikrotik. En el enrutamiento tienes redes broadcast. Nosotros no ponemos que sean de difusión y nombramos los vecinos NBMA. Eso recomendaban en los manuales de routeros. De todas formas, revisa el unsoloclic. La configuración que ofrece intercambia las 172 pero no las pone activas. Parece que estés haciendo lo mismo.
La configuración en este momento (--acacha 05:45, 23 nov 2010 (UTC)) es:
