NSX Federation Key Concepts
NSX Federation introduces some new terms and concepts in
VMware
Cloud Foundation
(VCF).NSX Federation Systems: Global Manager and Local Manager
An NSX Federation environment within VMware Cloud
Foundation includes two types of management systems.
Global Manager: a system similar to NSX Manager that federates multiple Local Managers.
Local Manager: an NSX Manager system in charge of
network and security services for a VMware Cloud Foundation instance.
NSX Federation Span: Local and Cross-Instance
When you create a networking object from Global
Manager, it can span one or more VMware Cloud Foundation instances.
Local: the object spans only one instance.
Cross-instance: the object spans more than one instance. You do not directly configure the span of a segment. A segment has the same span as the gateway it is attached to.
NSX Federation Tunnel Endpoints
In an NSX Federation environment, there are two types of tunnel endpoints.
Tunnel End Point (TEP): the IP address of a transport node (Edge node or Host) used for Geneve encapsulation within an instance.
Remote Tunnel End Points (RTEP): the IP address of a transport node (Edge node only) used for Geneve encapsulation across instances.
NSX Federation Tier Gateways
An NSX Federation in VMware Cloud Foundation
environment includes three types of tier-1 gateways.
Type | Description | Managed By | Scope |
|---|---|---|---|
standalone tier-1 gateway | Configured in the Local Manager and used for services such as the Load Balancer. | Local Manager | Single VMware Cloud Foundation instance |
local-instance tier-1 gateway | Configured in the Global Manager at a single location, this is a global tier-1 gateway used for segments that exist within a single VMware Cloud Foundation Instance. | Global Manager | Single VMware Cloud Foundation instance |
cross-instance tier-1 gateway | Configured in the Global Manager, this is a global Tier-1 gateway used for segments that exist across multiple VMware Cloud instances. | Global Manager | Multiple VMware Cloud Foundation instance |
