Appendix A Cisco 3825 Mobile Wireless Edge Router RAN-O Command Reference
The xconnect command with keyword ignore-vpi-vci results in the PVC mapping being done in a
cooperative way if the MWR works the same way as the receiving router. Without this command, the
MWR checks the VPI/VCI value inside PW packet for matches against the local configured PVC or
PVC-mapping. With the ignore-vpi-vci keyword configured, the MWR ignores the VPI/VCI header
inside the received PW packet and does a blind rewrite with the local configured AC-side PVC's
VPI/VCI value.
This applies only to N:1 VCC PW with N=1 special case.
Note
Examples The following example illustrates the configured xconnect service for an ATM interface by binding the
ATM circuit to the PW named 123 with a remote peer 10.0.3.201. The configuration settings in the
pseudowire-class named ATM-xconnect are used.
Router# config t
Router(config)# interface ATM 0/0/0
Router(config-if)# xconnect 10.0.3.201 123 pw-class ATM-xconnect
Router(config-if-xconn)# exit
Router(config-if)# exit
Router(config)# exit
The following example illustrates PVC mapping using the keyword ignore-vpi-vci with the xconnect
command. The example shows both the MWR and remote end (7600) routers.
MWR:
Router# config t
Router(config)# interface ATM 0/0
Router(config-if)# pvc 0/10 12transport
Router(config-if-atm-12trans-pvc)# encapsulation aa10
Router(config-if-atm-12trans-pvc)#
Router(config-if-atm-12trans-pvc-xconn)# exit
Router(config-if-atm-12trans-pvc)# exit
Router(config-if)# exit
Router(config)# exit
7600:
Router# config t
Router(config)# interface ATM 0/0
Router(config-if)# pvc 2/20 12transport
Router(config-if-atm-12trans-pvc)# encapsulation aa10
Router(config-if-atm-12trans-pvc)# xconnect 20.20.20.20 100 encapsulation mpls
Router(config-if-atm-12trans-pvc-xconn)# exit
Router(config-if-atm-12trans-pvc)# exit
Router(config-if)# exit
Router(config)# exit
