ospfv3LsdbApproachingOverflow
Module: OSPFV3-MIB
OID (symbolic): OSPFV3-MIB::ospfv3LsdbApproachingOverflow
OID (numeric): 1.3.6.1.2.1.191.0.9
Node type: NOTIFICATION-TYPE
Description: An ospfv3LsdbApproachingOverflow notification signifies that the number of LSAs in the router's link state database has exceeded ninety percent of ospfv3ExtAreaLsdbLimit.
What is ospfv3LsdbApproachingOverflow?
This notification is generated when the OSPF link state database reaches 90% of its maximum capacity, warning of an impending overflow condition. OSPFv3 routers maintain a database of network topology information, and exceeding limits can prevent proper routing updates. Network operators need to monitor this alarm to take preventive actions such as network restructuring, splitting areas, or upgrading hardware before the system becomes unstable.
Examples
Send this trap to an SNMP manager — replace <manager> with the IP or hostname of your monitoring server (SNMPv2c):
snmptrap -v2c -c public <manager> '' OSPFV3-MIB::ospfv3LsdbApproachingOverflow snmptrap -v2c -c public <manager> '' 1.3.6.1.2.1.191.0.9
Listen for incoming traps on the manager host (-f keeps it in the foreground, -Lo prints to stdout — useful for testing):
snmptrapd -f -Lo -c /dev/null authCommunity log public
Example snmptrapd log entry:
