This article provides the steps and considerations for distributing existing stretched networks across multiple VMware HCX Network Extension (NE) appliances after a Service Mesh scale-out.
The current Network Extension (NE) appliance hosting the stretched network does not automatically rebalance when additional NE appliances are deployed. The existing setup remains unchanged, and unextending or re-extending a network segment will not leverage the newly added NE appliances.
An HA group can only consist of one Active and one Standby NE appliance.
Creating a multi-Active/Standby HA group by adding additional NE appliances is not supported.
After enabling HA, HCX automatically selects an available NE appliance to form the HA pair. Manual selection of appliances is not possible.

To utilise newly deployed NE appliances, unextend existing stretched segments and recreate the extended network. During the creation process, the UI will provide an option to select the desired NE appliance, enabling manual distribution of stretched networks and ensuring efficient use of the additional appliances.
