867 VAE as PPPoE

[ciscovoipsupport]

I have being trying to config this router Cisco 867 VAE K9 for a while now.

since i am quite new to data, i m finding it a little difficut to configure the router.

I have a belkin router at home which i use for internet (pppoe)

I would like to know the basic requirement to setup this 867 VAE router as PPPoE.

Information i got from ISP.

----------------------------------

username

password

VPI/VCI = 1/32

IP is DHCP from ISP

Enacapsulation is LLC

MTU 1492

I have checked quite few post, now in a confused state on how to set this up!!!

Can anyone provide me a min running config that would help me to setup internet using this router..?

here is what i have tried so far:

!

wan mode dsl

!

interface ATM0

ip address dhcp

no atm ilmi-keepalive

pvc 1/32

  ppp chap hostname XXX

  ppp chap password 0 YYYY

  ppp pap sent-username XXX password 0 YYYY

  encapsulation aal5snap

!

!

Is it mandatory to use a dailer interface???

ISP has said the encapsulation is LLC! does aal5snap help in this case?

Hope someone can help me on this.

Hello,

Yes, it is mandatory to use Dialer interface. Your current configuration of the ATM interface appears to be partially correct. SNAP should be OK. Add these lines to your configuration please:

interface ATM0

  no ip address

  pvc 1/32

    no ppp chap hostname

    no ppp chap password

    no ppp pap sent-username

    pppoe-client dial-pool-member 1

    exit

  exit

!

interface Dialer1

  encapsulation ppp

  ppp chap hostname XXX

  ppp chap password YYY

  ppp pap sent-username XXX password YYY

  dialer pool 1

  ip address negotiated

  ip mtu 1492

  ip tcp adjust-mss 1452

  ip nat outside

You may copy-paste them into your config.

Let us know if this worked for you please!

Best regards,

Peter

Thanks Peter....

It worked perfectly..

Exept for a minor change

pppoe-client dial-pool-member 1 was not there..

replaced it with pppoe-client dial-pool-number 1

What all debug should i run to study and understand the working of PPPoE..?

Hi,

I apologize for getting back to this thread so late.

The PPPoE can be debugged using the following:

debug pppoe events

debug pppoe packets

Also, I would strongly advise you to read the RFC 2516 where the PPPoE is codified. The whole RFC has less than 18 pages and is easily readable. This document is the key to understanding what is inside the PPPoE.

Best regards,

Peter
