A ciscoMvpnMvrfChange notification signifies a change about a MVRF in the device. The change event can be creation of the MVRF, deletion of the MVRF or an update on the default or data MDT configuration of the MVRF. The change event is indicated by ciscoMvpnGenOperStatusChange embedded in the notification. The user can then query ciscoMvpnGenericTable, ciscoMvpnMdtDefaultTable and/or ciscoMvpnMdtDataTable to get the details of the change as necessary. Note: Since the creation of a MVRF is often followed by configuration of default and data MDT groups for the MVRF, more than one (three at most) notifications for a MVRF may be generated serially, and it is really not necessary to generate all three of them. An agent may choose to generate a notification for the last event only, that is for data MDT configuration. Similarly, deletion of default or data MDT configuration on a MVRF happens before a MVRF is deleted, it is recommended that the agent send the notification for MVRF deletion event only.
