PROBLEM SUMMARY:
****************************************************************
* USERS AFFECTED: All users of MPRoute. *
****************************************************************
* PROBLEM DESCRIPTION: MPRoute gets error "DTCMPR7828I Error *
* adding/deleting/changing stack rte" *
* when trying to delete TCP/IP stack *
* routes. *
****************************************************************
* RECOMMENDATION: APPLY PTF *
****************************************************************
When MPROUTE sends a command to the stack to add or delete a
route, the stack calls FindRoute to search the tree and
determine if the route is in the tree. FindRoute is not
finding the correct routing entry, so additions and deletions
may fail.
PROBLEM CONCLUSION:
When the stack has multiple routing entries to the same
destination with different subnetmasks, the routing tree
order can be corrupted when deleting routes. TreeDeleteNode
was changed to maintain the correct tree order when deleting
routing nodes. FindRoute was also changed to keep track of
the most specific route found so far and continue searching
as long as the subsequent nodes have a better match. This
ensures that FindRoute finds the best route.
