Hi Yogig,
The answer depends a little bit on which protocol/API you want to use.
The easiest answer: Use Solace Enterprise APIs (= SMF as protocol) - all these client APIs have the concept of a hostlist implemented.
The application will try to connect to all hosts in that hostlist one after the other until there is a successful connection.
And because you can’t connect to a shutdowned VPN (that’s the answer to the question “How to identify the VPN is down ?”. Answer: If you can connect, the VPN is NOT shutdowned), that does work automatically.

Often, such setups have a hostlist with 4 members: 2 hosts for the members of an HA cluster, and 2 hosts for the members of the DR-HA cluster.

Does that answer your questions ?
