[CAUSE] The vRtrMplsLspActivePathChanged notification is generated when the active path of an LSP successfully switches to an new path. This notification will also be sent when the active LSP path does not change but only the switch method changes on the path. The old LSP path index is specified by vRtrMplsLspOldTunnelIndex. The state and switch method of the current active LSP path are specified by vRtrMplsLspPathState and vRtrMplsLspPathActiveByManual respectively. [EFFECT] The switchover to the new LSP path was successful and/or the switch method of the current active LSP path changed. [RECOVERY] There is no recovery required for this notification.
