This notification is generated when we receive an LSP with a parse error. The isisCircIfIndex holds in index of the circuit on which the PDU arrived. The isisPduFragment holds start of the LSP, and the isisErrorOffset points to the problem. If the problem is a malformed TLV, isisErrorOffset points to start of the TLV and isisErrorTLVType holds the value of the type. If the problem is with the LSP header, isisErrorOffset points to the suspicious byte. The number of such LSPs is accumulated in isisSysStatLSPErrors.
