Chapter 21 Configuring Pseudowire
Configuring Hot Standby Pseudowire Support for ATM/IMA
Example: Pseudowire Redundancy
This example shows pseudowire redundancy configured for a CEM circuit (group). In the example, the
xconnect command configures a primary pseudowire for CEM group 0. The backup peer command
creates a redundant pseudowire for the group.
int cem 0/1
no ip address
cem 0
xconnect 10.10.10.1 1 encap mpls
backup peer 10.10.10.2 200
exit
Configuring Hot Standby Pseudowire Support for ATM/IMA
This section describes how to configure ATM/IMA pseudowire redundancy:
• Configuring ATM/IMA Pseudowire Redundancy in PVC Mode
• Configuring ATM/IMA Pseudowire Redundancy in PVP Mode
• Configuring ATM/IMA Pseudowire Redundancy in Port Mode
• Verifying Hot Standby Pseudowire Support for ATM/IMA
Note Both the primary and backup pseudowires must be provisioned for the Hot Standby Pseudowire Support
feature to work.
Configuring ATM/IMA Pseudowire Redundancy in PVC Mode
Complete the following steps to configure pseudowire redundancy in permanent virtual circuit (PVC)
mode.
