Table describes a list of possible SPF triggers:
Table 10-3 Reasons for SPF Log Trigger Events
Trigger Reason
PERIODIC Typically, every 15 minutes a router runs a periodic full SPF
calculation.
NEWSYSID A new system ID through the NET was configured on this router.
NEWAREA A new area (through NET) was configured on this router.
NEWLEVEL A new level (through is-type) was configured on this router.
NEWMETRIC A new metric was configured on an interface of this router.
IPBACKUP An IP route disappeared, which was not learned through IS-IS, but
through another protocol with better administrative distance. IS-IS will
run a full SPF to install an IS-IS route for the disappeared IP prefix.
IPQUERY A clear ip route command was issued on this router.
ATTACHFLAG This router is now attached to the Level 2 backbone or it has just lost
contact to the Level 2 backbone.
ADMINDIST Another administrative distance was configured for the IS-IS process
on this router.
AREASET Set of learned area-addresses in this area changed.
NEWADJ This router has created a new adjacency to another router.
DBCHANGED A clear isis * command was issued on this router.
BACKUPOVFL An IP prefix disappeared. The router knows there is another way to
reach that prefix, but has not stored that backup route. The only way to
find the alternative route is to run a full SPF run.
NEWLSP A new router or pseudonode appeared in the topology.
LSPEXPIRED Some LSP in the LSDB has expired.
LSPHEADER ATT/P/OL bits or is-type in an LSP header changed.
TLVCODE TLV code mismatch, indicating that different TLVs are included in the
newest version of an LSP.
TLVCONTENT TLV contents changed. This normally indicates that an adjacency
somewhere in the area has come up or gone down. Look at the "Last
trigger LSP" to get an indication of where the instability may have
occurred.
