Hello Team,
As I am studying Palo Alto and am a newbie, I have created a lab setup where I use BGP peering between a PA 850 and ISPs. The PA's IP, used for BGP peering, is also used for the IPsec tunnel. I discovered a vulnerability where an ISP outage results in no IP connectivity between the IPsec local and remote IPs, causing both Phase 1 and Phase 2 of the tunnel to go down. This setup is dependent on the ISPs.
Is it possible to:
I appreciate your response in advance!

In this scenario your IP connectivity depends on BGP to move your IP addresses around when there is an ISP outage.
Do you also have 'local' IP addresses provided by the ISP? This would allow you to set up 2 ipsec tunnels using the 'normal' (non BGP) public addresses so your tunnels do not depend on the BGP IP being moved around (as that will always lead to a tunnel outage)
