The default IP protocol valueis l2tp or 115, the L2TP protocol number.(Optional) Specifies the direction in which sequencing ofdata packets in a pseudowire is enabled:• transmit—Updates the Sequence Number field in theheaders of data packets sent over the pseudowireaccording to the data encapsulation method that is used.• receive—Keeps the Sequence Number field in theheaders of data packets received over the pseudowire.Out-of-order packets are dropped.• both—Enables both the transmit and receive options.Configuring the Xconnect Attachment CircuitSUMMARY STEPSDETAILED STEPSThis configuration procedure binds an Ethernet, 802.1q VLAN, or Frame Relay attachment circuit to anL2TPv3 pseudowire for xconnect service. The virtual circuit identifier that you configure creates thebinding between a pseudowire configured on a PE router and an attachment circuit in a CE device. Thevirtual circuit identifier configured on the PE router at one end of the L2TPv3 control channel must alsobe configured on the peer PE router at the other end.1. enable2. configure terminal3. interface type slot/port4. xconnect peer-ip-address vcid pseudowire-parameters [sequencing {transmit | receive | both}]Step 1Step 2Command or ActionenableExample:Router> enableconfigure terminalPurposeEnables privileged EXEC mode.• Enter your password if prompted.Enters global configuration mode.Example:Router# configure terminal62
