Figure 7-14. RBE Environment
To configure RBE, complete the steps for configuring the ADSL interfaces as
explained in “Configuring the ADSL Interface: the Physical Layer” on page 7-12.
Then configure the ATM interface as explained in “Configuring the Data Link
Layer for the ADSL Connection” on page 7-17 and configure the ATM subinter-
face as described in “Configuring a Subinterface for each PVC” on page 7-18.
When you configure the ATM subinterface, you must enter an additional
command. From the ATM subinterface configuration mode context, enter:
ProCurve(config-atm 1.1)# atm routed-bridged ip
Figure 7-15 shows the running-config for an ADSL connection that is using RBE.
