Redundant VPN to Azure using BGP
Hi all,
I'm trying to configure a reduntant VPN to azure using multiple ISP to the same azure VPN Gateway IP, according to this Microsoft document (https://docs.microsoft.com/en-us/azure/vpn-gateway/vpn-gateway-bgp-overview#multitunnel) this is possible using BGP. I have configure BPG according to this Watchguard doc (https://www.watchguard.com/help/docs/help-center/en-US/Content/en-US/Fireware/bovpn/manual/bovpn_vif_dynamic_routing_azure.html#AddVIF) but this documentation only instruct to make the VPN using only one gateway and one public Ip.
I have already configured a VPN to Azure using the previus documentation and using 1 of our public IP, I'm trying to configure a second VPN to the same Azure Gateway using another of our public IPs, but when I try to configure BGP for the second BOVPN, when I insert the Azure BGP Peer IP, I receive the error "The peer IP duplicate with another IP at BPVPN virtual interface.."
Do I need to add another BGP Peer IP to the Azure VPN Gateway? Have someone here configured this king of redundant VPN to azure?
Thanks and best regards,
Amedina

Amedinaj,
Have you found a solution?
I am working on the same thing. I have found some succeess if setup Azure for Active-Active and on the Firebox if I setup a 2nd Virtual BOVPN interface to the 2nd connection however the routing is not as seamless as I would hope.
