Command History
Usage Guidelines Use this command to establish the LDP session and to carry non-IP traffic. The default VPI VCI for the
co
ntrol VC is (0, 32). If for any reason you need to have a different control-VC, use the mpls atm
control-vc command to configure any VPI VCI allowed by the vpi and vci arguments for the control VC.
Examples The following example shows an MPLS subinterface and VPI 1 and VCI 34 as the control VCs:
Router(config)# interface atm4/0.1 mpls
Router(config-if)# mpls ip
Router(config-if)# mpls atm control-vc 1 34
