Hello every one,

Our company want to extend our existing on-premises data centers to OCI  us-phoenix-1 region. In order to achieve It, we have created an IPSec VPN
connection between our Customer-Premises Equipment(CPE) and Dynamic Routing Gateway(DRG)
Can you please let us know what is the best option below to make this connection highly available (HA)? and why?

1. Add another Dynamic Routing gateway In a different Availability Domain and create another IPSec VPN connection.
2. Add another Customer-Premises Equipment (CPE) and create second IPSec VPN connection with the same Dynamic Routing Gateway (DRG).
