After you enter this command, the router enters ATM VCconfiguration mode.Specifies ATM AAL5 encapsulation for the PVC.Step 6Example:Router(config-atm-vc)#encapsulation aal5xconnect peer-ip-address vcidpw-class pw-class-nameExample:Router(config-atm-vc)# xconnect10.0.3.201 888 pw-classatm-xconnectSpecifies the IP address of the peer PE router and the 32-bit VCI sharedbetween the PE at each end of the control channel.• The peer router ID (IP address) and virtual circuit ID must be a uniquecombination on the router.• pw-class pw-class-name—The pseudowire class configuration fromwhich the data encapsulation type (L2TPv3) is taken. The pw-classparameter binds the xconnect statement to a specific pseudowire class. Thepseudowire class then serves as the template configuration for allattachment circuits bound to it.NoteThe L2TPv3 session can also be provisioned manually. See the section“Manually Configuring L2TPv3 Session Parameters” for informationabout manually configuring the L2TPv3 session parameters.79
