A mvpnMvrfChange 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 I-PMSI or S-PMSI configuration of the MVRF. The change event is indicated by mvpnGenOperStatusChange embedded in the notification. The user can then query mvpnGeneralTable, and/or mvpnSpmsiConfigTable to get the details of the change as necessary. Note: Since the creation of a MVRF is often followed by configuration of I-PMSI and/or S-PMSIs 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 S-PMSI configuration. Similarly, deletion of I-PMSI and S-PMSI configuration on a MVRF happens before a MVRF is deleted and it is recommended that the agent send the notification for MVRF deletion event only.
