Abstract
The invention relates to a technique for protecting a point-to-multipoint primary tree in a connected mode communications network set up from a primary root node to leaf nodes in the event of a fault affecting the primary root node by means of a back-up tree between a back-up root node and at least one merge node, said at least one merge node belonging to a branch of the primary tree coming from the primary root node. A merge node executes the following steps:
