To configure, complete the following steps:
SUMMARY STEPS
1. enable
2. configure terminal
3. interface ATMslot/IMAgroup-number
4. xconnect ip-address port-number encapsulation mpls
DETAILED STEPS
Configuring an N-to-1 VCC Cell Mode
An N-to-1 Virtual Channel Connection (VCC) pseudowire allows you to map a ATM VCC to a
pseudowire. You must use an ATM adaptation layer (AAL) encapsulation for this transport type. To
configure, complete the following steps:
SUMMARY STEPS
1. enable
2. configure terminal
3. interface ATMslot/IMAgroup-number
4. pvc VPI/VCI l2transport
Command Purpose
Step 1
enable
Example:
Router> enable
Enables privileged EXEC mode.
• Enter your password if prompted.
Step 2
configure terminal
Example:
Router# configure terminal
Enters the global configuration mode.
Step 3
interface ATM
slot
/IMA
group-number
Example:
Router(config)# interface atm0/ima0
Specifies the slot location and port of IMA interface group and
configures the ATM interface.
• slot—Specifies the slot location of the ATM IMA port adapter.
• group-number—Specifies the group number of the IMA group.
Step 4
xconnect
ip-address port-number
encapsulation mpls
Example:
Router(config-if)# xconnect
10.10.10.10 20 encapsulation mpls
Binds an attachment circuit to the ATM IMA interface to create a
pseudowire.
