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.
