Abstract
A method of non-service affecting APS protection for MLPPP bundles on routing systems, and associated mechanism, including one or more of the following: specifying a working MLPPP bundle and a protection MLPPP bundle; specifying MLPPP parameters; associating the working MLPPP bundle and the protection MLPPP bundle with an APS circuit; bringing up an MLPPP session; changing an operational status of the working MLPPP bundle; synchronizing MLPPP state information between the working MLPPP bundle and the protection MLPPP bundle; and driving an operational status of the protection MLPPP bundle based on said changing the operational status of the working MLPPP bundle.
