198 Chapter 8: Using DSL to Access a Central Site

Example 8-20 shows the bridging conﬁguration for the DSL CPE. As you can see, the CPE

conﬁguration is the same when you conﬁgure the IRB over DSL.

Scenario 8-3: Conﬁguring PPPoA over DSL

In this scenario, you will conﬁgure the DSL solution to support data transport using PPPoA.

When completed, the Cisco 827 should train up with the DSLAM, and you should be able to

ping and access all normal network services from a client PC attached to the DSL CPE modem.

Figure 8-11 illustrates how these devices are interconnected.
