Command Mode
ROUTER ISIS (for IPv4)
CONFIGURATION-ROUTER-ISIS-ADDRESS-FAMILY-IPV6 (for IPv6)
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.
