LOCAL FIX:
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 *
****************************************************************
MPRoute and the stack both support up to 4 equal cost paths to a
single destination. MPRoute, however, maintains 2 lists - a new
list (of up to 4 equal cost paths) and the previous list (of up
to 4 equal cost paths). MPRoute first adds the new routes, and
then deletes the old routes. In the worst cast scenario, the
stack has 4 equal cost paths, and they all go down. MPRoute
could add 4 new ones, and then delete the 4 bad ones. So the
stack needs to accommodate 8 equal cost paths for MPRoute.
PROBLEM CONCLUSION:
The TCP/IP stack was changed to allow MPRoute to use up to
8 equal cost paths. These additional 4 paths will only be
used when routes are being added and deleted by MPRoute.
MPRoute still supports 4 equal cost paths, and static routes
added via the GATEWAY are still restricted to 4 equal cost
paths.
