Interface Specifiers
The configuration task examples in this chapter use the slot / port [. subinterface ] format
to specify the ATM physical interface on which you want to configure bridged
Ethernet. However, the interface specifier format that you use depends on the router
that you are using.
For ERX7xx models, ERX14xx models, and ERX310 router, use the
slot / port [. subinterface ] format. For example, the following command specifies
ATM 1483 subinterface 10 on slot 0, port 1 of an ERX7xx model, ERX14xx model,
or ERX310 router.
host1(config)# interface atm 0/1.10
For E120 and E320 routers, use the slot / adapter / port [. subinterface ] format, which
includes an identifier for the bay in which the I/O adapter (IOA) resides. In the
software, adapter 0 identifies the right IOA bay (E120 router) and the upper IOA bay
(E320 router); adapter 1 identifies the left IOA bay (E120 router) and the lower IOA
bay (E320 router). For example, the following command specifies ATM 1483
subinterface 20 on slot 5, adapter 0, port 0 of an E320 router.
host1(config)# interface atm 5/0/0.20

routers, see Interface Types and Specifiers in

Configuring Bridged Ethernet
This section shows how to configure IP with PPPoE terminated at the E Series router.
With each step, an illustration shows how the router is building the interface columns.
Configuring IP with PPPoE Terminated at the Router
This section shows how to create IP with PPPoE interfaces that terminate the
connection and route the data received on the PVC, as shown in the example in
Figure 41 on page 444. To create a terminated PVC:
1.
Create an ATM 1483 subinterface and associated PVC.
host1(config)# interface atm 9/1.1 point-to-point
host1(config-subif)# atm pvc 1 0 32 aal5snap 0 0 0
