Cisco 887/897 e Fastweb Fibra VULA - Problema dhcp

Postby massimiliano.picco » Sun 06 Aug , 2017 5:14 pm

Buongiorno a tutti,

sono passato di recente ad una connessione a fastweb VULA da una precedente connnessione sempre fastweb in ADSL.

Ho modificato la configurazione per utilizzare l'interfaccia corretta (Ethernet0) e ricevere l'indirizzo in dhcp.
La portante si allinea correttamente ma non riesco ad ottenere la lease dell'indirizzo da dhcp.

ho provato a lasciare la configurazione della int minimale

interface Ethernet0
description "Fastweb VDSL"
ip address dhcp
!

ma ottengo sempre errori di questo tipo:

hai provato con il comando ip address negotiated?
Dovrebbe risolvere il tuo problema.

Facci sapere

Ciao, ho controllato ma tra i comandi relativi all'interfaccia non ho "ip address negotiated".

Non utilizzo un dialer perchè dalla poca documentazione che ho trovato ho visto che fastweb dovrebbe utilizzare ipoe e quindi teoricamente dovrebbe bastare attivare il dhcp sull'interfaccia wan del router (nel mio caso eth 0)
