Command History
Version Description

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.
