Module: RFC1248-MIB
OID (symbolic): RFC1248-MIB::ospfSpfRuns
OID (numeric): 1.3.6.1.2.1.13.2.1.4
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: The number of times that the intra-area route table has been calculated using this area's link-state database. This is typically done using Dijkstra's algorithm.
What is ospfSpfRuns?
This counts how many times the intra-area route table has been recalculated (typically via Dijkstra's SPF algorithm) using this area's link-state database. A rapidly increasing count points to topology instability -- links flapping or routers going up and down -- forcing frequent SPF recalculations in that area.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.13.2.1.4 snmpwalk -v2c -c public <target> RFC1248-MIB::ospfSpfRuns
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.13.2.1.4.1 snmpget -v2c -c public <target> RFC1248-MIB::ospfSpfRuns.1
