Chapter 6: Monitoring the Routing Engine Understand What Happens When Memory Failures Occur Most Juniper Networks Routing Engines support Error Checking and Correction (ECC) protected memory. There are two types of memory errors: single-bit and multiple-bit. A single-bit error is when a single 0 or 1 bit is incorrect. The system detects and corrects single-bit errors, then logs the event in the file.
