I've successfully installed and integrated VRNI 4.0 with my vSphere 6.7 and NSX 6.4.4
But i have one little issue - VM Path Topology doesnt't work correctly for VMs which are located at regular (non-NSX) Port Groups
For example Path to Internet throws the following error 'Unable to determine path: Unable to determine router for Gateway IP 10.10.40.1'
10.10.40.1 is the gateway (SVI) on a physical switch
The same thing with a VM on NSX network works just fine
We get routing information from NSX controller for NSX logical switches but for Non-NSX PGs, physical switches must be added as data sources in vRNI,
Once you add supported physical switch to vRNI, it will start showing the path.
