set-overload-bit
Configure the router to set the overload bit in its non-pseudonode LSPs. This prevents other routers from using it as an
intermediate hop in their shortest path first (SPF) calculations.

Version 7.8.1.0 Added support for multi-topology ISIS.
Version 6.3.1.0 Introduced.
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.
