Chapter 34 Configuring MPLS, MPLS VPN, MPLS OAM, and EoMPLS
Enabling EoMPLS
This example shows how to configure pseudowire redundancy as a switchover to the peer with the IP
address 10.1.1.12 immediately when a failure occurs and to not switch back to the primary VC when it
becomes available.
Switch#
config t
Switch(config)#
interface gigabitethernet1/1/1
Switch (config-if)#

This example shows the output of the show mpls l2transport vc privileged EXEC 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
Forcing a Manual Switchover to the Backup Pseudowire VC
You can manually force the router to switch to the backup or primary pseudowire. You can specify either
the interface of the primary attachment circuit or the IP address and VC ID of the peer router. If the
specified interface or peer is not available, the switchover does not occur. The backup pseudowire
becomes active when you enter the command.
Beginning in privileged EXEC mode, follow these steps to force a pseudowire switchover:
This command forces a switchover to the peer with the IP address 10.1.1.4 and VCID 33.
Switch#
xconnect backup force-switchover peer 10.1.1.4 33
Monitoring L2VPN Pseudowire Redundancy
Use the privileged EXEC commands in
Table 34-2
to verify or monitor pseudowire redundancy.
Step 7
show xconnect all
Verify the configuration.
Step 8
copy running-config startup-config
(Optional) Save your entries in the configuration file.

Specify that the router should switch to the backup or to the
primary pseudowire when the command is entered.
