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:

Cisco 887/897 e Fastweb Fibra VULA - Problema dhcp

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)

Se a qualcuno dovesse servire, il problema sta nel fatto che il server dhcp risponde sulla vlan 100.
