Figure 38: Example of PPPoE over ATM Stacking

Use to configure a PVC on an ATM interface.
The following parameters are mandatory:
vcd —Virtual circuit descriptor, which identifies a virtual circuit in the range
1–2147483647. The vcd is a unique number that you assign, which identifies a virtual
circuit. The vcd value has no relationship to the vpi and vci values and has meaning
only to the E Series router.
vpi—Virtual path identifier of the PVC. The VPI is an 8-bit field in the ATM cell header.
The VPI value is unique on a single link, not throughout the ATM network, because
it has meaning only to the E Series router. The VPI value must match the value on
the switch. The parameters vpi and vci cannot be both set to 0; if one is 0, the other
cannot be 0.
vci —Virtual channel identifier. The VCI is a 16-bit field in the ATM cell header. The
VCI value is unique on a single link, not throughout the ATM network, because it has
meaning only to the E Series router. The parameters vpi and vci cannot be both set
to 0; if one is 0, the other cannot be 0.
encapsulation type:
aal5snap—Specifies a logical link control (LLC) encapsulated circuit. An
LLC/Subnetwork Access Protocol (LLC/SNAP) header precedes the protocol
datagram.
aal5mux ip—Specifies a multiplexed circuit used for IP only.
aal5autoconfig—Enables the autodetection of a 1483 encapsulation (LLC/SNAP
or VC multiplexed).
