Configuring the Xconnect Attachment Circuit for ATM Port Mode Cell Relay
over L2TPv3
The ATM Port Mode Cell Relay feature packs ATM cells arriving at an ingress ATM interface into
L2TPv3 data packets and transports them to the egress ATM interface. A single ATM cell is encapsulated
into each L2TPv3 data packet.
Perform this task to enable the ATM Port Mode Cell Relay over L2TPv3 feature.
SUMMARY STEPS
1. enable
2. configure terminal
3. interface type slot/port
4. xconnect peer-ip-address vcid pw-class pw-class-name
Step 5
encapsulation aal0
Example:
Router(config-atm-vc)#
encapsulation aal0
Specifies ATM AAL0 encapsulation for the PVC.
Step 6
xconnect peer-ip-address vcid
pw-class pw-class-name
Example:
Router(config-atm-vc)# xconnect
10.0.3.201 888 pw-class
atm-xconnect
Specifies the IP address of the peer PE router and the 32-bit VCI shared
between the PE at each end of the control channel.
• The peer router ID (IP address) and virtual circuit ID must be a unique
combination on the router.
• pw-class pw-class-name—The pseudowire class configuration from
which the data encapsulation type (L2TPv3) will be taken. The pw-class
parameter binds the Xconnect statement to a specific pseudowire class.
The pseudowire class then serves as the template configuration for all
attachment circuits bound to it.
Note The L2TPv3 session can also be provisioned manually. See the section
“Manually Configuring L2TPv3 Session Parameters” for information
about manually configuring the L2TPv3 session parameters.
