ospfMtSpfRuns
Module: OSPFv2-MT-MIB
OID (symbolic): OSPFv2-MT-MIB::ospfMtSpfRuns
OID (numeric): 1.3.6.1.2.1.0.1.3.2.1.3
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: The number of times the SPF is run for a given topology.
What is ospfMtSpfRuns?
This read-only Counter32 counts how many times the SPF (shortest-path-first) algorithm has run for a specific topology within an OSPF area. An admin monitors it to detect topology instability, since a rapidly increasing count signals frequent recalculations, likely from flapping links or unstable adjacencies in that topology. For example, if ospfMtSpfRuns jumps from 50 to 500 within a minute, it points to a route-flapping problem in that topology's area.
