Juniper Apstra

Juniper's intent-based networking software that designs, deploys and validates multivendor data center fabrics.

Definition

Apstra uses blueprints and reference designs (3-stage and 5-stage Clos, collapsed fabrics) to generate device configurations for EVPN-VXLAN fabrics, continuously validates intent against telemetry and supports Junos, SONiC and other vendors' switches.

Example

An Apstra blueprint deploys an EVPN-VXLAN fabric with virtual networks across 24 QFX leaves.

Exam tip

Apstra is intent-based: you declare the desired fabric, and it renders and validates configs.
