Meaning

This LSP event indicates that even though the active physical path has changed, the LSP stays up. Because this network configuration has an alternate (fast-reroute) path available, the event is a Change in active path rather than a Session preempted event.

Cause

The active path might have failed.

Action

Not applicable.
