Configuring The Pseudowire Using Pseudowire Class - Cisco 3845 - Security Bundle Router Software Manual

Chapter 34 Configuring MPLS, MPLS VPN, MPLS OAM, and EoMPLS
This example shows how to set the MTU value on an SVI.
Switch(config)# interface vlan 100
Switch(config-if)# xconnect 2.2.2.2 2 encapsulation mpls
Switch(config-if)# mtu 9000

Configuring the Pseudowire Using Pseudowire Class

The pseudowire-class configuration specifies the characteristics of the tunneling mechanism, including
encapsulation type and control protocol. You must specify the encapsulation mpls command as part of
the pseudowire class for the AToM VCs to work properly.
Beginning in privileged EXEC mode, follow these steps to configure a pseudowire class:
Step 1 configure terminal
Step 2 pseudowire-class name
Step 3
encapsulation mpls
Step 4 preferred-path interface tunnel tunnel-id
Step 5
end
Step 6
show mpls l2transport vc [detail]
Step 7
copy running-config startup-config
This example configures the pseudowire class test.
Switch# config t
Switch(config)# pseudowire-class test
Switch(config-pw-class)# encapsulation mpls
This example shows the output of the show mpls l2transport vc command when the primary
attachment
circuit is up and the backup attachment circuit is available, but not currently selected.
Switch# show mpls l2transport vc
Local intf Local circuit Dest address VC ID Status
------------- -------------------------- --------------- ---------- ----------
Vl20 Eth VLAN 20 10.1.1.2 20 UP
Vl20 Eth VLAN 20 10.1.1.4 20 DOWN
This example shows how to display the preferred path using the show mpls l2transport vc 2 detail
command.
Switch# show mpls l2transport vc 2 detail

Enter global configuration mode.
Create a pseudowire class with the specified name and enter
pseudowire class configuration mode.
Specify tunneling encapsulation. For AToM, the
encapsulation type is mpls.
(Optional) Specify the path that pseudowire traffic uses to be
an MPLS TE tunnel.
Return to privileged EXEC mode.
Verify the configuration.
(Optional) Save your entries in the configuration file.
