ATM0 is initializing, line protocol is down

[simmete]

Ciao,

sto cercando di configurare un CISCO877-k9 per una ADSL interbuisness (Multigroup telecom), ho provato qualche configurazione postata ma sembra non agganciare la portante....

Dando uno show interfaces ATM 0 vedo questo:

Codice: Seleziona tutto

ATM0 is initializing, line protocol is down
  Hardware is MPC ATMSAR (with Alcatel ADSL Module)
  MTU 4470 bytes, sub MTU 4470, BW 4608 Kbit, DLY 80 usec,
     reliability 255/255, txload 1/255, rxload 1/255
  Encapsulation ATM, loopback not set
  Encapsulation(s): AAL5  AAL2, PVC mode
  10 maximum active VCs, 1024 VCs per VP, 0 current VCCs
  VC Auto Creation Disabled.
  VC idle disconnect time: 300 seconds
  Last input never, output never, output hang never
  Last clearing of "show interface" counters never
  Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0
  Queueing strategy: Per VC Queueing
  5 minute input rate 0 bits/sec, 0 packets/sec
  5 minute output rate 0 bits/sec, 0 packets/sec
     0 packets input, 0 bytes, 0 no buffer
     Received 0 broadcasts, 0 runts, 0 giants, 0 throttles
     0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort
     0 packets output, 0 bytes, 0 underruns
     0 output errors, 0 collisions, 0 interface resets
     0 output buffer failures, 0 output buffers swapped out

E nella sezione di configurazione ho messo

Codice: Seleziona tutto

interface ATM0
 no ip address
 no ip redirects
 no ip unreachables
 no ip proxy-arp
 ip route-cache flow
 no atm ilmi-keepalive
 dsl operating-mode auto
!
interface ATM0.1 point-to-point
 description $ES_WAN$$FW_OUTSIDE$
 ip address 88.XXX.XXX.46 255.255.255.252
 ip nat outside
 ip virtual-reassembly
 pvc 8/35
  encapsulation aal5snap
 !
!

Dove puo' essere l'errore? (La linea va in quanto con un altro router funziona correttamente...)

Grazie in anticipo.

telefona il supporto telecom e apri un guasto!

... ma come mai allora se attacco un router Zyxel Prestige 650 che ho configurato la scorsa settimana funziona?

(P.S: Ho chiamato la telecom... attendo che mi richiamino)

[spooke]

posta la conf e vediamo se va bene..

[simmete]

Dunque, l'errore precesente lo ho risolto cambiando:

Codice: Seleziona tutto

dsl operating mode auto

in

Codice: Seleziona tutto

dsl operating mode ansi

Ora sono alle prese con il NAT:

I dati fornitomi dalla Telecom sono questi:
punto punto: 88.xx.yy.46 mask 255.255.255.252
ip assegnati: 88.kk.zz.184-191 mask 255.255.255.248
(qundi il GW dovrebbe essere il 88.kk.zz.185)

Il router si trova all'indirizzo interno 192.168.0.7 mask 255.255.255.0
vorrei sapere come configurare correttamenet le routes per il NAT, ho visto in giro nel forum ma non me ne funziona una...

Questa e' la mia conf attuale:

Ciao, prova ad aggiungere queste stringhe:
