You need also to remember that in many cases the DSL link is not provided by the actual ISP. In many cases this is a wholesale scenario which uses L2TP to forward the PPP session from the telco/DSL provider to the ISP. In many cases there would also be another L2TP hop to another sub-ISP/customer. Arie On Wed, Apr 22, 2009 at 7:01 PM, Curtis Maurand <cmaurand@xyonet.com> wrote:
I don't understand why DSL providers don't just administratively down the port the customer is hooked to rather than using PPPoE which costs bandwidth and has huge management overhead when you have to disconnect a customer. I made the same recommendation to the St. Maarten (Dutch) phone company several years ago. They weren't listening either. That way you can rate limit via ATM or by throttling the port administratively.
Just a suggestion

Hello Nanog!
i just would like to see how other operators are handling broadband/DSL subscribers in their BRAS. Currently, we are implementing PPPoE with AAA on our Redback SE's and Cisco boxes. As our subscriber base grows and grows, management of user logins, passwords, password resets, password changes are getting really huge. Some customers also complains about the method of logging in, asking for an easier way to do it or dump logins altogether. We're looking at DHCP/CLIPS for Redback but haven't really tested it since it requires a new license for it. For Cisco, we've been empty so far in looking for a solution wherein we still have accounting and rate-limiting on subscriber vc's.
how are network operators in your areas do it? DHCP? if i do DHCP, will i still have the flexibility of sending a radius reply attribute so i could rate-limit the subscribers speed? or still offer speed on demand via radius/time-based upgrade of their rate-limits during off-peak hours?
thank you for any insights that you may share.
