Forwarding information base: the lookup table an NSX Edge compiles from its RIB. It is one of the things the EdgeRouting ODS runbook examines, and VCF Operations for networks harvests the Edge routes held in it.
Also called forwarding information base.

Each book explains FIB in context, with comparison tables and the common traps.
Terms in this definition
- LOOKUP
Inside a visual calculation, this DAX function retrieves a value from the visual matrix using whatever filters you supply, and works out any you omit from the context it is evaluated in.
- Event
Table in Log Analytics where entries from Windows event logs are kept.
- NSX Edge
Appliance that gives NSX external routing and hosts centralised services; it is deployed as a VM on ESX or on physical hardware. Tier-0 gateways need it, as do Tier-1 gateways running stateful services like NAT.
- RIB
Table where a router keeps the routes it has learned, used to build the forwarding information base (FIB). The EdgeRouting runbook in NSX ODS examines a logical router's RIB, FIB and ARP entries.
- EdgeRouting
Diagnostic runbook from NSX ODS. Feed it a logical router together with two IP addresses and it checks how healthy Edge routing is, reads the RIB, FIB and ARP entries, and then pings and traces the path.
- ODS
The On Demand Support capability in NSX that executes built-in runbooks (for instance BgpNeighborState or EdgeRouting) one step at a time, finishing each with a report and artefacts to inspect or export.
- Runbook
An Azure Automation job script, in PowerShell, Python or graphical form, executed in an Azure sandbox or on a Hybrid Runbook Worker; a typical example resizes a VM at scheduled times.
- VCF Operations for networks
Add-on that gives VCF insight into its networks: platform and collector appliances work together to examine micro-segmentation, flows, paths and network assurance.
