Aiuto per conf. Cisco 1720 e Libero ADSL Flat 4Mb
Inviato: lun 07 mag , 2007 8:45 am
Ciao a tutti!! Questo è il mio primo post nel forum. Mi sono avvicinato da poco al "mondo" Cisco acquistando un 1720 di seconda mano e premetto che sono un esordiente nel campo del networking "adulto" (come penso possa essere definito quello che comprende l'impiego di apparecchi Cisco e la voglia di imparare a fare e a capire, piuttosto che attaccare 2 cavetti, premere un pulsante e vedere che tutto avviene praticamente da solo). Premesso questo, ho letto e cercato nel forum e ho capito che probabilmente preparare una configurazione per l'ADSL di Libero non è così semplice. Un po' basandomi su una conf di un amico che ha però Alice adsl e quello che ho trovato qui sul forum, ho messo insieme una conf: inutile dire che non funziona...
Provo a postarla qui, nella speranza che mi possiate illuminare!!

Il router è un Cisco 1720 con IOS 12.2(15)T5 (lo stesso ios che il mio amico ha sul suo 1720 col quale si collega ad Alice)
Loggando il comando debug all ho ottenuto quello che segue (è una parte dato che si ripete dopo un po'):
