Bonsoir Martin,

The answer was no.

To be more exact, the sink side of a locked LSP, PW, Section, has to
inform its clients.

Isn't this notification already caused by the locking at the
far end?
Or is the locking only applied in one direction of a bi-directional
path? If yes, then the notification is not required.

Cheers, Huub.
