Figure 8-10 RBE Scenario

In Example 8-17, the PVC is mapped from the Cisco 827 DSL connection (ATM1/2) to the

DSLAM trunking port (ATM0/1).

In Example 8-18, the PVC is conﬁgured from the DSLAM to the NSP and NRP. Interface

ATM8/0/0 is the network line card, and interface ATM1/0/0 is the NRP.

Example 8-19 shows the RBE conﬁguration for the NRP. You saw the conﬁguration steps in the

previous section.
