This notification is generated only after the number of routes contained by the specified VRF reaches or attempts to exceed the maximum allowed value as indicated by mplsVrfMaxRouteThreshold, and then falls below this value. The emission of this notification informs the operator that the error condition has been cleared without the operator having to query the device.

Note that mplsVpnVrfConfRouteMaxThreshTime denotes the interval at which the the mplsNumVrfRouteMaxThreshExceeded notification will be re-issued after the maximum value has been exceeded (or reached if mplsVpnVrfConfMaxRoutes and mplsVpnVrfConfHighRouteThreshold are equal) and the initial notification has been issued. Therefore, the generation of this notification should also be emitted with this same frequency (assuming that the error condition is cleared). Specifically, if the error condition is reached and cleared several times during the period of time specified in mplsVpnVrfConfRouteMaxThreshTime, only a single notification will be issued to indicate the first instance of the error condition as well as the first time the error condition is cleared.

This behavior is intended to prevent continuous generation of notifications by an agent in the event that routes are continually added and removed to/from a VRF after it has reached its maximum value. The default value is 10 minutes. If this value is set to 0, the agent should issue a notification whenever the maximum threshold has been cleared.
