Cisco Router as PPPoE Server

swiri

Hi all,

Just wondering if anyone has ever used a Cisco Router as a PPPoE Server to simulate a connection to Eircom? I would greatly appreciate it if someone could provide an example config.

Here is a simple network diagram:

They cover such a configuration in CCNA, however I don't know if all the details you would require (such as DHCP etc.) are given. Here is a config page:

What router are you using? I think the above presumes the connection over a serial connection, or over LAN, but I don't know about PSTN...

Thanks for the reply Dardania.

I passed the CCNA back in Feb, unfortunately they only mention PPPoE very briefly. I wish it was covered! I think it might be covered in the CCNA SP (Service Provider) Concentration.

I have a number of Cisco routers including a 851W (DSL) and 877 (ADSL).

If I can get a PPPoE client example I might be able to create a config for a PPPoE Server. I'll keep looking.

You could use 7210 so dynamips would work as a bras. https://supportforums.cisco.com/thread/2017691?tstart=0#3075008

Thanks noclee. That looks very complicated, bit over my head tbh :-)

I just tried setting up a PPPoE connection using the Cisco Configuration Professional Web tool but it failed. I may have used wrong settings.

The config it passed to the router was:

interface Vlan1
ip tcp adjust-mss 1412
exit
interface ATM0
no shutdown
exit
interface ATM0.1 point-to-point
no shutdown
pvc 8/35
pppoe-client dial-pool-number 1
exit
exit
interface Dialer0
exit
default interface Dialer0
interface Dialer0
ip mtu 1452
no shutdown
ip address dhcp
dialer pool 1
dialer-group 1
encapsulation ppp
dialer idle-timeout 120
dialer fast-idle 20
ppp authentication chap callin
ppp chap hostname eircom@eircom.net
ppp chap password 0 ******
exit
dialer-list 1 protocol ip permit

I must try again and turn on debugging for chap
Is it chap or pap that eircom use?
Also is the password just eircom?

Rackstar

AFAIK its CHAP

The eircom password is Broadband1, think broadband1 also works!

I configured some 877M's on Eircom there a while back.

I documented it on my blog if it helps?

PS: Had to troubleshoot it a little!

Thanks Rackstar. Balls I was using eircom as the password.

I dont have an eircom ADSL connection here to test it with. Will give it a go again tomorrow.

Thanks john, that helps a lot, a good reference for PPPoE config!
