In OcNOS, ERPS with CFM Down-MEP over Bridge-Domain combines the benefits of Ethernet Ring Protection Switching (ERPS) with Continuity Fault Management (CFM), ensuring faster traffic switchover and enhancing network resilience. This feature enables the configuration of ERPS over Layer 2 sub-interfaces mapped under bridge-domains, optimizing network resource utilization. It offers the flexibility to configure Layer 2 sub-interfaces as ring ports and supports the creation of multiple ERPS instances for various logical ERPS rings.
