There are two versions of Rendezvous available:
- Version 1 (V1): supports bypassing the Citrix Cloud Connectors for HDX session traffic only.
- Version 2 (V2): supports bypassing the Citrix Cloud Connectors for both control traffic and HDX session traffic.

Instructions

To use Rendezvous protocol, Citrix policy [Rendezvous protocol] needs to be enabled.
https://docs.citrix.com/en-us/citrix-virtual-apps-desktops/policies/reference/ica-policy-settings.html#rendezvous-protocol
This is the common setting for Rendezvous V1 and V2.
 

To check if Rendezvous V2 is enabled or not, GctRegistration registry value is necessary to be confirmed.
On the VDA machine, check the following registry value:

Key: HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\VirtualDesktopAgent
Value type: DWORD
Value name: GctRegistration

If the value data is 1, that means Rendezvous V2 has been configured. Otherwise, it is Rendezvous V1.
