Hi,
I have three 1721s that have been using a simple ethernet config to access the Internet via my ISP. Now I've added a fourth 1721 and this one was given five static IPs that are "sticky" and thus my connection is now PPPOE.
My question is how do I modify the config below (which is standard across all three 1721s) so that it does the connection via PPPOE? I've been reading around this forum and Googling but thought I'd pose the question here as well.
Thanks in advance and let me know if more information is needed.
Cheers,
Jon
PS - The first three routers are using 12.3, the new router is using 12.4.

Hello Jon,
you are using a BVI as the interface pointing to the Internet, I am not sure if you can tie this to the ATM. Is there a specific need to use integrated routing and bridging ?

Hi GP,
Thanks for getting back to me. This config represents how SBC set up their DSL at that time (~1 year ago). Now, they use the "sticky" scenario with PPPOE. My thoughts are I need to adjust my config to match something like this:
http://www.dslreports.com/faq/3643
or follow these guidelines for PPPOE:

What do you think? Let me know if this clarifies things for you.
Thanks,
Jon
