b. Configure bit-error-triggered PW switching.
# Configure bit-error-triggered PW switching on the AC interface of the CSG.
[CSG] interface gigabitethernet 1/0/2.10
[CSG-GigabitEthernet1/0/2.10] mpls l2vpn pw bit-error-detection
[CSG-GigabitEthernet1/0/2.10] quit
# Configure bit error detection to trigger PW switchovers on the AC interface of RSG1.
[RSG1] interface eth-trunk 10.1
[RSG1-Eth-Trunk10.1] mpls l2vpn pw bit-error-detection
# Configure bit error detection to trigger PW switchovers on the AC interface of RSG2.
[RSG2] interface eth-trunk 10.1
[RSG2-Eth-Trunk10.1] mpls l2vpn pw bit-error-detection
NOTE
This example shows how to configure bit-error-triggered single-segment (SS)-PW switching. To
configure bit-error-triggered multi-segment (MS)-PW switching, you also need to run the mpls
switch-l2vc ip-address vc-id between ip-address vc-id encapsulation encapsulation-type bit-
error-detection command to enable bit-error-triggered protection switching on superstratum
provider edges (SPEs).
Verify the configuration.
# Run the display bfd bit-error-detection session all command on the CSG to view BFD
bit error information.
[CSG] display bfd bit-error-detection session all
