We are looking to build Redundant VPN between On Prem Firewall and Azure through site to site VPN.
On firewall side we have single IP shared on both both firewalls so redundancy is achieved there, need more understanding on azure side.
why to go for Active-active Azure VPN gateway ? if Azure VPN gateway itself offer redundancy is my basic question ?
As we cannot control traffic coming from Azure in Active Active , how to tackle with Asymmetric issue ?
BGP really Required for Active Active Model ?
Ikev1 or Ikev2 ? Any specific reason to go for IKEV2 ?
Thanks for help in advance.
