Recommended Releases
Junos OS Evolved Release 25.2X100D21 is the current recommended release for the AI-ML data center network feature set. The first release introducing the EVPN-VXLAN multi-tenancy feature set on QFX switches for the AI-ML data center usecase was Junos OS Evolved Release 23.4X100D20. We recommend approaching the Juniper Networks representative or partner for the latest release recommendation.

Upgrading to a Recommended Release
In an AI-ML data center deployment, the large data flows, also known as elephant flows, traveling through the network mean that even a low percentage of lost traffic can be a large number of packets. As the network administrator, you can use the unified in-service software upgrade (unified ISSU) feature to upgrade to a more recent release of Junos OS Evolved with no disruption on the control plane and minimal loss of traffic.
Benefits of Unified ISSU
-
Eliminates network downtime during software image upgrades.
-
Reduces operating costs while delivering higher service levels.
-
Enables you to implement new features more quickly.
