ABSTRACT:
The present invention provides a protection providing method in a network configuration having a customer edge apparatus redundantly connected to a first provider edge apparatus and a second provider edge apparatus for setting a primary provider edge apparatus and a secondary provider edge apparatus with the customer edge apparatus. The first provider edge apparatus transmits a first signaling message received when establishing a pseudowire to the customer edge apparatus. The second provider edge apparatus also transmits a second signaling message received when establishing a pseudowire to the customer edge apparatus. The customer edge apparatus compares the first and second signaling messages and sets the primary provider edge apparatus and the secondary provider edge apparatus.
