Hi,
Nothing to worry.
Find the url which will help you to configure PPoE in cisco router.
In the below example use your ethernet interface instead of ATM
http://www.cisco.com/en/US/tech/tk175/tk15/technologies_configuration_example09186a008071a6c3.shtml
http://www.cisco.com/en/US/tech/tk175/tk15/technologies_configuration_example09186a008071a799.shtml
Hope it will helps u to configure PPoE in cisco 3845 router.

Hi,
Instead of ATM , you have to use your current interface which is going to connect your ISP from your router and configure ppoe in that interface.

Hi,
As per your configuration you have one E1 controller card and 2 Giga interfaces in your router.
Can you tell me about your internet connection. ?? -- If yes then connect your internet link into one of the gigabitethernet port and configure that interface as ppoe interface.
Is the internetconnection via ethernet connection or connected via any modem ?? --

Hi,
Can you paste the router current running configuration.
DHCP is not necessary to configure,that is used to assign the IP dynamically to your desktops.

03-04-2010 05:50 PM
Hi,
Have you tried to configure the below lines in your router.
vpdn enable
no vpdn logging
vpdn-group pppoe
request-dialin
protocol pppoe
Can you paste the output of the below command
#sh ip int br
Even if you are not able to access internet, contact your ISP.
regards
karuppu
03-04-2010 06:17 PM
Hi,
Now, configuration wise everything is ok.Better check with your ISP.
GigabitEthernet0/1 unassigned YES unset down down
I hope the cable is coming from your modem to router might be not working.befor contact with ISP check that
cable because the interface is down now.
If both your router and modem's are powered on then it should be up

When you are at the router save the config by issuing this command
"wr" after that your config is saved and when your reboot the router you don't loose your config any more

Hi,
Can you paste the sh version of your router.susecting the config-register value.
regards
karuppu
03-05-2010 07:48 PM
Hi,
You need to change the config register in to 0x2102.the configuration register shows 0x2142. The router bypasses the startup configuration stored in NVRAM during its boot sequence. This feature is normally used during a password recovery procedure.
router(config)#config-register 0x2102
then write the confiig. reload you router.

Hi,
No problem. See In which interface you have terminated your internet(DSL) link to your router.It should be either your ethernet interface or your serial interface.
can you paste the sh running-configuration and sh interface of your router
