Dialer 0 up up, Virtual-Access1 up down

[spooke]

ciao a tutti
mi succede spesso che con una connessione alice flat dopo un po di tempo che sono connesso non riesco piu' a navigare, faccio uno sh d0
e ottengo:

Dialer0 is up, line protocol is up (spoofing)
Virtual-Access1 is up, line protocol is down

sapete da cosa deriva questo problema?
esiste un modo per far ristabilire la connessione istantaneamente ogni volta che il protocollo del virtuall-access va giu'?
grazie a tutti

Postaci la configurazione e dacci un'idea degli usi che fai della connessione e vediamo di lavorarci.
