EVPN Active-Standby in OcNOS provides a solution for availability and resiliency in network environments. By implementing Single-Active or Port-Active redundancy mechanisms within the EVPN Multihoming framework, OcNOS ensures continuous connectivity even in the event of a Provider Edge (PE) device failure. With Single-Active, one PE device remains active while the other stands by, ready to take over if needed. Port-Active allows multiple PE devices to be active simultaneously, each with specific ports, ensuring efficient traffic routing. This feature enhances network fault tolerance, minimizes downtime, and optimizes data exchange, improving network reliability.
