set-overload-bit
The LSP overload bit is enabled for the IS-IS routing process to ensure that no paths
through the BSR are seen by other routers in the IS-IS area when the Link State
routing table on the BSR is incomplete or inaccurate. However, IP and CLNS prefixes
directly connected to the BSR continue to be reachable.
Use the set-overload-bit command in Router Configuration mode to allow other
routers on the network to ignore IS-IS routing problems on the BSR in their SPF
calculations until the IS-IS routing process on the BSR has recovered from its
problems, as shown below:
