High Availability

  • MNHA support for Express Path (SRX4600, SRX5400, SRX5600, SRX5800 [IOC3, IOC4])—Express Path, formerly services offloading, in Multinode High Availability (MNHA) (SRG0 and SRG1+) reduces latency and ensures seamless packet forwarding post failover. MNHA creates stateful and static services offloading sessions on the other node for immediate readiness, prevents premature session aging, preserves session integrity, and manages first packet processing during primary role transitions. The system also terminates and reinstalls services offload sessions in the newly failed node for accurate management. MNHA systems in Layer 3 (Routing) mode support this functionality.
