To support SRX chassis cluster design, two special interface types are required:

fab (fabric) interfaces for data plane synchronization and control interfaces for control plane communication between the nodes in the cluster.

The exhibit shows a hierarchical structure with Leaf, Spine, and Super Spine layers. This architecture is characteristic of a 7-stage IP fabric, which is used in large-scale data centers to provide high scalability and bandwidth. It extends the 3-stage fabric by adding an additional spine layer (Super Spine) for interconnecting multiple spine layers.

Reducing the oversubscription ratio means provisioning more uplink bandwidth relative to access bandwidth, which improves congestion handling and performance but also increases network cost due to the need for additional or higher-capacity links and equipment.

To ensure encryption of traffic between customer sites over a Layer 3 VPN, the most effective solution is IPsec with ESP (Encapsulating Security Payload). ESP provides both encryption and authentication, ensuring data confidentiality and integrity across the service provider network.

Secure Vector Routing (SVR) is specifically designed for SD-WAN environments with limited bandwidth, as it offers encrypted and policy-based routing with minimal overhead compared to protocols like IPsec or GRE. This makes it ideal for bandwidth-constrained branch sites.

In a 3-stage IP fabric, each leaf node must connect to every spine node to ensure full mesh connectivity at Layer 3 between leafs via the spine layer. This design supports ECMP and optimal traffic distribution across the fabric.

Encrypted Traffic Insights is a Juniper ATP Cloud feature that detects threats within HTTPS trafficwithout decrypting it. It uses metadata, machine learning, and behavioral analysis to identify anomalies while maintaining privacy.

cSRX and vSRX are the virtualized versions of the Juniper SRX Series firewalls designed for deployment in virtual environments. The cSRX is containerized, while the vSRX is a VM-based firewall, both supporting advanced security services in cloud or virtualized data centers.
