Azure BGP

[HS08]

I have 2 different internet connection on my fortigate, then i build vpn site to site from internet-A  to the azure and configure the BGP and the connectios was established with below details.

Azure BGP ASN is 65515 and peer ip is 172.16.0.64

Fortinet Local ASN is 65103, then in the interface tunnel i set the IP 10.103.103.103 for local peer and remote IP is 172.16.0.64 255.255.255.255

When j try to build 2nd vpn site to site from internet-B to azure, the tunnel is up but the BGP was not established because if i set remote ip in the interface tunnel to 172.16.0.64 255.255.255.255 the fortigate say that ip already used in 1st tunnel.

Also in the BGP neighboor what interface should i use for interface and update source bexause i have 2 internet connection. If i create another local BGP ASN in the fortigate, when i specifiyng ip 172.16.0.64 the fortigate also say the peer ip is duplicated.

Anyone know how we can setup BGP for 2 different connection if the destionation only have 1 BGP ASN and 1 BGP peer ip?

I think that a loopback interface can help in this scenario. Some of the configuration details are shared in this article.
