204 Chapter 8: Using DSL to Access a Central Site

Practical Exercise 8-1: PPPoA over DSL

In this practical exercise, both lab-827A and lab-827B are connected to the DSLAM, as shown

in Figure 8-13. You need to create two different DSL proﬁles—premium and standard. Each of

them has a different downstream and upstream speed. Assign a premium DSL proﬁle to lab-827A

and a standard DSL proﬁle to lab-827B. In this exercise, you will conﬁgure local authentication.

IP addresses are assigned to the DSL CPEs from the IP pool conﬁgured in the Cisco 6400.
