We have a PA with two VPNs configured. VPN-Main is the active one and if this vpn falls, the traffic must go through the other VPN-backup. The fact is that when the active VPN falls, the route that has the Palo Alto continues going through the previous VPN, it does not refresh the route and adds it through the new tunnel.
This configuration worked when this deployment was done but suddenly stop working.
We have configured a tunnel monitor with destination IP and profile fail-over.
In VPN Main (active):
In VPN (backup):
And this is the route table:
tunnel.29 is the main (active). The metric is 2.
tunnel.27 is the backup. Metric is 5.
Why PA is not deleting the "active" route if the monitor ip is down through the vpn down.

I found that static route path monitoring is what I need with this situation. Thanks for your help.

To avoid tunnel flaps with multiple Proxy-IDs defined, it is possible to specify which Proxy-ID should be used:
set network tunnel ipsec TUNNEL tunnel-monitor destination-ip 192.168.1.1 tunnel-monitor-profile tunnel-monitor-failover proxy-id XXX
