Please Help!

I want to replace a BT Internet modem with a cisco 2811 ADSL ISR.

Please what information do I need to get from BT to successfully configure the ADSL router.

Regards

Well, generally your provider will provide you with either a static address or assigned address. You'll need to contact your provider to see if it's a PPPoE account (uses username and password to get logged in). After that, you would configure your dialer interface, assign it to your public interface on your 2811, and that should be it. I'm assuming that BT is your internet provider?

Cheers John,

I can see on the BT (internet) modem that it's a PPPoA, 0/38. Also I have that username & password to get logged in.

BT also gave me a range of (5) static IP Address for my network:

81.x.x.x. to 81.x.x.y

with a Gateway 81.x.x.z and subnet mask 255.255.255.248

However what I am not sure of is if I should configure my Dialer interface with IP Address DHCP or static.

Also do I need to configure interface BVI1.....Sorry, I am a bit confused.

Thanks

Take a look at this document. It should give you step-by-step instructions on how to configure your router:

Re: Please Help!

Dear,

Could you please tell me if the user/password that you have are to log to the router or the PPPoE connection ? that's not the same thing.

The IP address may be attributed to you by DHCP, to see make the IP address as negotiated (to be DHCP) on the Dialer interface.

Is it OK ? or need more information ??
