Abstract
In general, techniques are described for preparing a computer network for planned events. A network device comprising a control unit and an interface implements these techniques. The control unit is configured to be a member a maintenance association that verifies connectivity a single service instance. The interface outputs a maintenance message to an additional network device to verify connectivity between the network device and the additional network device. The control unit receives an indication to initiate a planned event capable of disrupting the maintenance association. Prior to the control unit performing the planned event, the interface generates a modified maintenance message indicating that the planned event will be performed by the network device. The interface then transmits the modified outgoing maintenance message to the additional network device to direct the additional network device to avoid detecting the planned event as a connectivity fault.
