Appendix A Cisco 3825 Mobile Wireless Edge Router RAN-O Command Reference xconnect 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. Note This applies only to N:1 VCC PW with N=1 special case. 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.
