ADSL WAN Connections
ADSL Modules for the ProCurve Secure Router
For example, to assign the ATM subinterface a VPI/VCI of 0/33, enter:
ProCurve(config-atm 1.1)# pvc 0/33
Defining the ATM Encapsulation
The ATM Data Link Layer for the ADSL connection includes these sublayers:
■ the ATM adaptation layer (AAL), which is called Layer 2-1
■ the point-to-point layer, which is referred to as Layer 2-2
You must configure the adaptation layer by specifying an encapsulation type.
Enter one of the following commands to enable the encapsulation type
specified by your service provider:
Syntax: encapsulation aal5snap
or
Syntax: encapsulation aal5mux [ip | ppp]
The default setting is aal5snap, which establishes an encapsulation type that
supports the Link Layer Control/Sub-Network Access Protocol (LLC/SNAP).
AAL5 LLC/SNAP encapsulation works with any type of protocol for the ADSL
connection: bridging, PPPoA, PPPoE, and IP with and without bridging.
Use the aal5mux encapsulation setting for multiplexed virtual circuits. You
must then specify a protocol for each subinterface to use: IP or PPP.
If your service provider is using PPPoE, you must set the encapsulation to
aal5snap or aal5mux ppp, as shown below:
ProCurve(config-atm 1.1)# encapsulation aal5snap
or
ProCurve(config-atm 1.1)# encapsulation aal5mux ppp
Assigning the ATM Subinterface an IP Address
If you are configuring just ATM as the Data Link Layer protocol, you assign
the IP address to the ATM subinterface. If you are configuring PPPoE or
PPPoA, you assign the IP address to the PPP interface.
