Enabling Loop Detection Globally

Before enabling loop detect on an interface, you must enable loop detect in the system view.

Perform the following steps on PEs.

Run system-view
The system view is displayed.
Run loop-detection enable
The loop detection is globally enabled.
(Optional) Run loop-detection identifier identifier-value
An authentication identifier for L2VPN loop detection has been configured.

This step can be performed only after L2VPN loop detection is enabled globally.
