Graceful-Restart Helper-Reject; Ip Ospf Auth-Change-Wait-Time - Dell Force10 MXL Blade Reference Manual

By default, FTOS implements an enhanced flooding procedure that dynamically and intelligently
determines when to optimize flooding. Whenever possible, the OSPF task attempts to reduce flooding
overhead by selectively flooding on a subset of the interfaces between two routers.
