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.

NOTE: Enables you to configure a single system wide value that is common for both IPv4 and IPv6

address.
