You need to remember that Palo Alto FW is using route base VPN in contrast of policy based.

Which means the that the routing table of the firewall dictates which traffic to which tunnel it will be sent.

So if I understand correctly in your case you have:

- One tunnel to IKE peer A and this tunnel is using local and remote proxy-id of 0.0.0.0/0

- Second tunnel to IKE peer B and this tunnel is using proxy-id local 10.125.0.0/16 and remote 10.17.xx.xxx/25

Such configuration is totally fine and it should work as long as:

- The two tunnel are using different remote IKE VPN peers

- You have proper routing for the traffic over the two tunnels.
