This holds the size of an LSP we received that is too big to forward. This notification-only object reports the exact byte size of an LSP the router could not forward or process because it exceeded some limit, the direct diagnostic evidence needed to decide whether to raise ciiSysReceiveLSPBufferSize rather than just knowing generically that an oversized LSP occurred. For example, a trap showing this object at 3200 bytes against a locally configured receive buffer size of 1492 tells the admin exactly by how much the buffer needs to grow to accommodate that LSP.
