On affected versions earlier than 11.6.0, there are dual management routes in the main routing table. On version 11.6.0, you might also receive an error upon querying SNMP ipCidrRouteTable and/or snmpd core.


In versions earlier that 11.6.0, conditions are unknown other than observing the dual management routes in the main routing table. On version 11.6.0, the condition is snmpwalking ipCidrRouteTable.
