Chapter 4 Configuring the Cisco MWR 2941 Router Using the CLI
Configuration Sequence
• Configuring GRE Tunneling
• Using Pseudowire Labels
• Configuring a Backup Peer
• Configuring Structure-Agnostic TDM over Packet (SAToP)
• Configuring Circuit Emulation Service over Packet-Switched Network (CESoPSN)
• Configuring Transportation of Service Using ATM over MPLS
• Configuring Transportation of Service Using Ethernet over MPLS
For full descriptions of each command, see Appendix B, “Cisco MWR 2941 Router Command
Reference.” For pseudowire configuration examples, see Appendix A, “Sample Configurations.”
Using Pseudowire Classes
A pseudowire class allows you to create a single configuration template for multiple pseudowire
connections. You can apply pseudowire classes to all pseudowire types. Follow these steps to configure
a pseudowire class:
Step 1 Enter the following commands to create the pseudowire class.
a. Enter configuration mode.
Router# configure terminal
b. Use the pseudowire-class command to create a new pseudowire class.
Router(config)# pseudowire-class newclass
c. Use the encapsulation command to set an encapsulation type. Use MPLS encapsulation for ATM
over MPLS.
Router(config-pw-class)# encapsulation mpls
d. Use the mpls experimental command to specify the 3-bit EXP field in the MPLS label used for
pseudowire packets.
Router(config-pw-class)# mpls experimental 5
Note For more information about the mpls experimental command, see Appendix B, “Cisco MWR 2941
Router Command Reference.”
e. If there are multiple paths that traffic can cross within the pseudowire class, use the preferred-path
command to specify a preferred path.
Router(config-pw-class)# preferred-path peer 50.0.0.1
Note This command only applies to MPLS pseudowires.
Step 2 Follow these steps to create a reference to the pseudowire class in the ATM IMA interface.
a. Configure the pseudowire interface that you want to use the new pseudowire class. This example
shows an ATM IMA interface.
Router(config)# interface atm0/ima0
