          Definition:
               The total number of IP datagrams which local IP user-
               protocols (including ICMP) supplied to IP in requests for

          Definition:
               The number of output IP datagrams for which no problem
               was encountered to prevent their transmission to their
               destination, but which were discarded (e.g., for lack of
               buffer space).  Note that this counter would include
               datagrams counted in ipForwDatagrams if any such packets
               met this (discretionary) discard criterion.

               Counter

          Definition:
               The number of IP datagrams discarded because no route

               Note that this counter includes any packets counted in
               ipForwDatagrams which meet this "no-route" criterion.
               Note that this includes any datagarms which a host cannot
               route because all of its default gateways are down.

               The number of failures detected by the IP re-assembly
               algorithm (for whatever reason: timed out, errors, etc).
               Note that this is not necessarily a count of discarded IP
               fragments since some algorithms (notably the algorithm in
               RFC 815) can lose track of the number of fragments by
               combining them as they are received.
