This read-only Counter tracks the number of times a route learned via OSPF was not added to the IP Routing Table due to insufficient table space, a condition the MIB documents as currently always reporting zero. An administrator can rely on ppeOspfRouteDiscards staying at zero on this firmware even under heavy OSPF load. For example, the admin notes ppeOspfRouteDiscards remains at zero during a large-scale OSPF route redistribution test, consistent with the documented behavior for this counter.
