stò smanettando per configurare un router 1760 con onboard una seriale WIC1T.
Questo router è collegato tramite cavo V35 al DCE del fornitore (penso albacom).
Sinceramente sono scarsino con l'interfacce seriali per questo tipo di connessioni, ci stò studiando ma è alquanto un casino!!! visto che IOS e da poco che ci studio
Il router ha solo il compito di nattare tutto il traffico nella rete locale classica 192.168.0.X
le specifiche che mi ha fornito il provider sono:
Ac1-na1
Interface ATM9/0/0.40134 point-to-point
mtu 1500
ip address X.255.4.77 255.255.255.252
pvc 40/134
ubr 1536
encapsulation aal5snap
max-reserved-bandwidth 100
Pool X.221.217.160 255.255.255.240
IP Wan Cliente X.X.4.78/30
DLCI 100 ietf
Ho letto i vari post ma non ho capito se è necessaria un'interfaccia seriale virtuale (Serial0/0.1) e come configurarla per nattare il traffico.
Chiedo aiuto ad un'anima pia che mi faccia luce!!!!1
!
interface Serial0/0
no ip address
encapsulation frame-relay
no shutdown
!
interface Serial0/0.1 point-to-point
ip address x.x.x.x x.x.x.x
frame-relay interface-dlci x IETF
!
ip route 0.0.0.0 0.0.0.0 Serial0/0.1
!
Poi dovresti controllare che il DLCI della linea con il comando:
show frame pvc
Devi vedere se è attivo oppure no!
Spero di averti detto giusto.... e che qualcuno di più esperto di me non mi tiri le orecchie visto che sono anche nuovo!
mi sono fatto aiutare dal tecnico per i parametri di configurazione e sono arrivato al punto di aver caricato tutto ma l'interfaccia seriale NON VA IN UP rimane sempre in down come se non sentisse il DCE che è collegato correttamente con interfaccia V35.
In allegato posto la configurazione e lo sh int
Grazie
