Command History
Version 9.0(1.3) Introduced on the S5000.
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.
