management, route sharing, and diagnostics to support the QFabric system. Routing
Engines for control plane functions are virtual entities that run on the Director group.
• Fabric management protocol —A link-state protocol runs on the control plane network
to identify and initialize QFabric system resources, support device redundancy, and
support management communication throughout the QFabric system. The protocol
is enabled by default.
Control Plane Services
The QFabric system control plane provides the infrastructure to support the following
services for the QFabric system:
• System initialization
•
Topology discovery
•
Internal IP address and unique ID assignment
• Route information sharing
• Configuration delivery to Node devices
•
Interdevice communication between Node devices, Interconnect devices, and the
Director group
Many of these services are provided by the external Routing Engines that run in software
on the Director group.
