### Instruction:
ISIS-4-REDIST_FAIL
### Response:
(Severity: 4), (Category: ROUTING), (Description: The RIB returned an unexpected error when IS-IS attempted to (de)register for the redistribution of routes in the specified topology and owned by the specified protocol. If this is a registration error then routes from the specified protocol may not be advertised in IS-IS's system LSPs. If this is a deregistration error then IS-IS may receive unnecessary redistribution updates from the RIB but the system LSPs will be correctly generated. The problem may be caused by a low memory condition but is most likely to be an internal programming error.), (Recommended Action: Reduce other system activity to ease memory demands. If conditions warrant, upgrade to a larger memory configuration.. Consider restarting the IS-IS and/or the RIB processes. *RECUR*.)
