Usage
Information
Configure the router to set the overload bit when a router experiences problems, such as a memory
shortage because of an incomplete link state database. This 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 recovere
d.
NOTE: You can configure a single system wide value that is common for both IPv4 and IPv6 address.
