Chapter 4 Configuring the Cisco MWR 2941 Router Using the CLI
Configuration Sequence
Configuring N-to-1 VPC Cell Transport
An N-to-1 VPC cell transport pseudowire maps one or more ATM virtual path connections (VPCs) to a
single pseudowire. While the configuration is similar to 1-to-1 VPC cell mode, this transport method
uses the N-to-1 VPC Pseudowire protocol and format defined in RFCs 4717 and 4446. Follow these steps
to configure an N-to-1 VPC pseudowire.
Step 1 Configure the ATM IMA interface.
Router(config)# interface atm0/ima0
Router(config-if)#
Step 2 Use the atm pvp command to map a PVP to a pseudowire
Router(config-if)# atm pvp 10 l2transport
Router(cfg-if-atm-l2trans-pvp)#
Step 3 Use the xconnect command to bind an attachment circuit to the ATM IMA interface to create a
pseudowire. This example creates a pseudowire by binding the ATM circuit 305 to the remote peer
30.30.30.2.
Router(cfg-if-atm-l2trans-pvp)# xconnect 30.30.30.2 305 encapsulation mpls
Router(cfg-if-atm-l2trans-pvp-xconn)#
Step 4 Use the end command to exit configuration mode.
Router(cfg-if-atm-l2trans-pvp-xconn)# end
Router#
Configuring ATM AAL5 SDU VCC Transport
An ATM AAL5 SDU VCC transport pseudowire maps a single ATM PVC to another ATM PVC. Follow
these steps to configure an ATM AAL5 SDU VCC transport pseudowire.
Step 1 Configure the ATM IMA interface.
Router(config)# interface atm 0/ima0
Router(config-if)#
Step 2 Use the pvc command to configure a PVC and specify a VCI/VPI.
Router(config-if)# pvc 0/12 l2transport
Router(cfg-if-atm-l2trans-pvc)#
Step 3 Use the encapsulation command to set the PVC encapsulation type to AAL5.
Router(cfg-if-atm-l2trans-pvc)# encapsulation aal5
Note You must use AAL5 encapsulation for this transport type.
Step 4 Use the xconnect command to bind an attachment circuit to the ATM IMA interface to create a
pseudowire. This example creates a pseudowire by binding the ATM circuit 125 to the remote peer
25.25.25.25.
Router(cfg-if-atm-l2trans-pvc)# xconnect 25.25.25.25 125 encapsulation mpls
