Feature Overview (aka. Goal Summary)  

With the introduction of User Defined Networks (UDN) in OVN-Kubernetes, provide observability (GUI and CLI) of all UDN network segments and objects assigned to those network segments. 

Goals (aka. expected user outcomes)

OpenShift users on OVN-Kubernetes will be able to create additional primary network segments for pods, VMs, applications and services, and will expect to be able to visualize topologically and using netobserv-cli:

• the different UDNs (including the default used for cluster control plane/API)
• pod and VM objects assigned to each UDN
• routes configured between UDNs
• all namespaces assigned to UDNs

Requirements (aka. Acceptance Criteria):

Anyone reviewing this Feature needs to know which deployment configurations that the Feature will apply to (or not) once it's been completed.  Describe specific needs (or indicate N/A) for each of the following deployment scenarios. For specific configurations that are out-of-scope for a given release, ensure you provide the OCPSTRAT (for the future to be supported configuration) as well.

Use Cases (Optional):

• As a cluster admin, I want to see what UDNs have been created, what routes established between them, and pods/VMs within them, both visually and from the CLI. 
• As a developer, I want to be able to see my assigned UDNs and corresponding routes, visually and from the CLI. 

Questions to Answer (Optional):

Out of Scope

Background

Customer Considerations

Documentation Considerations

Interoperability Considerations

• How does this align to the OCP Virt topology viewer?
