The Virtual Chassis Fabric Best Practices Guide provides network architects and designers with best practice guidelines for designing, deploying, and configuring a Juniper Networks Virtual Chassis Fabric (VCF). This best practices guide also provides a high-level overview of certain VCF concepts and behaviors, and prescriptive advice on how to maintain your VCF.
VCF is a low-latency, high-performance fabric architecture that uses a spine and leaf topology to combine multiple devices—QFX5100, QFX3600, QFX3500, and EX4300 series switches—into a resilient fabric architecture that is managed as a single device. VCF is optimized to support small and medium-sized data centers that contain a mix of 1-Gbps, 10-Gbps, and 40-Gbps Ethernet interfaces.
