How does Validate Commit function work in PAN OS 9.0.9?

[Luke_Franzelas]

 I'm wondering if the validation process is checking the change against the running config and not taking into account the Interface IP change in the candidate config while doing the validation.

I am trying to make a change to both the IP address of the outside interface and the associated default static route

When a validate commit I get the following error 

Static route default route next hop IP x.x.x.x is not in subnet of outgoing interface ethernet1/3

Now I've checked. I have no typos in my interface address or my route and I've used a default.  the next hop address is the first useable in the  /29 subnet and the ethernet1/3 is the last useable address in the subnet.

If you want you can test commit force https://live.paloaltonetworks.com/t5/general-topics/difference-between-commit-and-commit-force/td-p/... to bypass the check in your case but be carefull and read about this. Also make certain that you are changing the IP addresses on the interface as when I use CLI many times  I add an ip address and the old still there, so I end up with 2 IP addresses, so use the GUI and first remove the old one then add the new.
