This holds the size of ciiSysLevelOrigLSPBuffSize advertised by the peer in the originatingLSPBufferSize TLV. This notification-only object captures the buffer-size capability the peer itself advertised, exactly the comparison point needed when an oversized-LSP event occurs to determine whether the peer genuinely originated an LSP bigger than it claimed to support, versus the local router's own receive buffer simply being smaller than what the peer legitimately advertises. For example, a trap showing this peer-advertised buffer size at 4096 bytes while the locally received LSP that triggered the event is only 3800 bytes would reveal the problem is the local router's own smaller receive buffer, not any fault on the peer's part.
