Usage
Information
Set the overload bit when a router experiences problems, such as a memory
shortage due to an incomplete link state database which can result in an
incomplete or inaccurate routing table. If you set the overload bit in its LSPs, other
routers ignore the unreliable router in their SPF calculations until the router has
recovered.
