Recommendations

The 5-Stage EVPN/VXLAN Fabric with Juniper Apstra JVD follows an industry-standard ERB design. This JVD, provides tips and recommendations at several points in this JVD.

Junos OS Release 23.4R2-S3 is the minimum recommended software version for this JVD.

Extending EVPN networks across multiple pods within the same Apstra blueprint adds the following value:

• Scaling: provide any-to-any connectivity for applications distributed across multiple pods.
• Redistributing Workloads: To load-balance applications, you can migrate a group of applications from one pod to another pod while preserving application IP and MAC addresses.
• Performing pod maintenance: Migrate all applications from one pod to another, while preserving the application IP and MAC addresses.
• Active / Standby applications across sites / pods: Deploy A/S applications across multiple pods to provide high availability at pod level, or as part of application migration tasks.
• Facilitate external connectivity for a virtual network from a remote pod without external connectivity.

One of the important feature of Apstra 5.0 is the introduction of custom telemetry combined with Probes to monitor any non-native configuration deployed using configlets. For example, OSPF in case of OISM .

This document validates the architecture. The hardware selected in (Table : Platform Positioning and Roles) are the best-suited switch platforms in terms of features, performance, and the roles that are specified in this JVD.
