1. A method for reconfiguring information from redundant grand master (GM) clocks representing network elements in a gPTP (Generalized Precision Time Protocol) network, the method comprising:
transmitting a teardown message from one network element to an adjacent network element,
with information about the redundant GM clocks contained in the teardown message, downgrade at least one of the redundant GM clocks in the network elements of the network to become a subordinate clock,
after the teardown message is received by the adjacent network element, removing the information contained in the teardown message from a local database of the adjacent network element that received the teardown message, and
selecting a new best GM clock after the information contained in the teardown message has been removed from the local database.
