ipSystemStatsOutForwDatagrams OBJECT-TYPE

    DESCRIPTION

            final IP destination and for which it was successful in
            finding a path to their final destination.  In entities
            that do not act as IP routers, this counter will include
            only those datagrams that were Source-Routed via this
            entity, and the Source-Route processing was successful.

            When tracking interface statistics, the counter of the
            outgoing interface is incremented for a successfully
            forwarded datagram.

            Discontinuities in the value of this counter can occur at
            re-initialization of the management system, and at other
            times as indicated by the value of
