Hello again sir, the configuration is not workin do i need to put an ip dhcp pool? but i dont know how. sorry to bother you again, hope you have a great day

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.

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 05:53 PM

vpdn enable
no vpdn logging
vpdn-group pppoe
request-dialin
protocol pppoe
but the last line is not available its just l2tp but still i put the protocol pppoe
this is the sh ip int brief
Interface IP-Address OK? Method Status Prot

GigabitEthernet0/0 192.168.10.3 YES manual down down
GigabitEthernet0/1 unassigned YES unset down down
Service-Engine1/0 unassigned YES unset administratively down down
NVI0 unassigned NO unset up up
Dialer1 unassigned YES manual up up

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

Karuppu
Just have a look of my BOLD LETTERS once again
03-04-2010 06:20 PM

can i ask a question again, whats the command for the router so it will load its start up config when ever i turn it off? i keep on copyng the start up to runnn everytime i turn it off.
03-05-2010 06:57 PM
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
