OSPF/3/OVERFLOW:OID [oid]: The LSDB overflows. (ProcessId=[process-id], RouterId=[router-id], ExtLsdbLimit=[lsa-limit], InstanceName=[instance-name])
The Overflow feature restricts only the total number of Type 5 and Type 7 LSAs. The total number of type 5 LSAs and type 7 LSAs in the LSDB of the switch reached or exceeded the maximum value defined by ospfExtLsdbLimit. The possible cause was that the number of routes imported by OSPF exceeded the set threshold. This trap was generated when the number of OSPF external routes in the network reached or exceeded the configured overflow limit.
| Name | Meaning |
|---|---|
oid |
Indicates the MIB object ID of the alarm. |
ProcessId |
Indicates the process ID. |
RouterId |
Indicates the ID of the switch that generates the trap message. |
ExtLsdbLimit |
Indicates the maximum number of type 5 LSAs and type 7 LSAs. |
InstanceName |
Indicates the instance name. |
The number of type 5 and type 7 LSAs exceeds the limit allowed by overflow. The excessive type 5 and type 7 LSAs are discarded.
If so, go to Step 2.
If not, go to Step 3.
If it is allowed to adjust the maximum number of external LSAs in the OSPF LSDB, run the lsdb-overflow-limit command to reconfigure the maximum value. The set maximum value should be consistent on the entire network. Wait for a period of time and check whether the trap is cleared. If the trap is cleared, go to Step 4. If not, go to Step 3.
If it is not allowed to adjust the maximum number of external LSAs in the OSPF LSDB, go to Step 3.
