Figure 45: Dynamic PPP Interface Columns

Figure 46 on page 529 shows dynamic PPPoE interface columns and illustrates how
PPPoE supports multiple IP sessions over each ATM 1483 circuit.

Figure 46: Dynamic PPPoE Interface Columns

You can specify either or both 

ppp

 and pppoe for the interface by specifying the

auto-configure

 command for each type of interface. The first packet received defines

the type of dynamic interface that is created.

Configuring a PPP or PPPoE Dynamic Interface

To configure an ATM 1483 subinterface to support a PPP or PPPoE dynamic interface:
