    Understanding Junos Fusion

    Junos Fusion technology, based on the IEEE 802.1BR standard, is a rich, open framework that makes networks highly versatile, extensible, and responsive in multivendor environments. With Junos Fusion technology, network administrators can reduce network complexity and operational expenses by collapsing underlying network elements into a single, logical point of management using QFX Series and EX Series switches running the Junos operating system.

    Junos Fusion consists of two major components—aggregation devices and satellite devices.

    Aggregation devices serve as the core of a Junos Fusion fabric and are responsible for almost all management tasks, including interface configuration for every satellite device interface in the topology. An aggregation device runs Junos OS for the entire Junos Fusion. The network-facing interfaces on the satellite devices—extended ports—are configured from the aggregation device and support features that are supported on Junos OS running on the aggregation device. A Junos Fusion fabric can have one aggregation device (single-home Junos Fusion) or two aggregation devices (multihome or dual-home Junos Fusion).

    Satellite devices form the access layer of a Junos Fusion fabric. These devices, which are connected through uplink ports to the aggregation devices, need not be individually managed as the control plane resides on the aggregation device.
