Re: Broadband Subscriber Management

[Arie Vayner <arievayner () gmail com>]

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.
