FIELD: radio engineering, communication.
SUBSTANCE: invention relates to setting up networks and more specifically to synchronisation of a label distribution protocol (LDP) and an interior gateway protocol (IGP) for broadcast networks without causing non-optimum traffic rejection. A broadcast interface is used to carry traffic on a label-switched path. If an alternative path exists, the broadcast interface will not be declared a broadcast network until LDP becomes operational for all neighbours on the broadcast interface.
EFFECT: invention discloses an element having a broadcast interface to a broadcast network which in turn becomes operational, determines if at least one alternative path to the broadcast network exists.
