how to set pppoa adsl with fix ip address on cisco 877?

[weerapatr]

I purchase a cisco 877 router and package adsl with fix ip address how to config it.

I found a way config with interface dialer with negotiate ip addresss which I think this is adsl with dynamic ip address.

Config ip address on interface atm0/0?

Config ip address on interface dialer?

Please advice and ref.

Thank in advance

Hi

That ip address has to be mentioned in Dialer interface not atm interface.

PPPoA architecture can be found at :

http://www.cisco.com/warp/public/794/pppoa_arch.html

And the configuration guide can be found at:

Please ask ISP if they are using "bridged RFC 1482 or RFC 2684". If yes, then configure:

bridge irb

interface atm0.1 point-to-point

pvc

bridge-group 1

interface bvi1

ip nat outside

ip address

bridge 1 protocol ieee

bridge 1 route ip

Hope this helps, please rate post if it does!
