How to adjust VIP setting from an iApp

Question

Hi,
I have to adjust virtual-address settings from an iApp.
The iApp create a single VS, with an unused destination-IP. So the associated VIP is automatically created. But I have to advertise this IP inside OSPF, so I would-like to do this in the iApp.
If I use this line :
iapp::conf create ltm virtual-address /Common/${::vs__vip} route-advertisement enabled

the VIP is created with required parameters, but the virtual-ip is depending on the application :
1.1.1.6 without iapp::conf create ltm virtual-address1.1.1.10 with iapp::conf create ltm virtual-address

And the VIP cannot be modified, either inside or outside the iApp (changing traffic-group of the iApp or of the VIP for example) because of the application dependence. 
Do you know how to set default VIP settings ? Like advertisement, arp, etc. 
Thank you for your responses,

Adding "app-service none" to the virtual-address command will detach it from the iapp, allowing you to modify it at-will later on. (Note that since it is no longer managed by the iapp, the virtual-address will not be deleted when the iapp is deleted.)
iapp::conf create ltm virtual-address /Common/$::vs__vip route-advertisement enabled app-service none

Hi Fred,
With app-service none this application dependency disappear in VIP list, but it's still impossible to modify the iApp traffic-group :

Do you have any idea?

There must be more to it.  I cannot reproduce your problem by simply changing the traffic-group.&nbsp;

Hi,&nbsp;
I've recreate a simplified iApp to test that.&nbsp;
You should manage to import this template.&nbsp;
Create an instance with 10.10.10.10 as vip and traffic-group-X as iApp traffic-group (should be ok)Modify the vip with 10.10.10.11 (should be ok)Modify the iApp traffic-group with traffic-group-Y ("should" not be ok) 
01070734:3: Configuration error: The virtual address (/Common/10.9.8.7) can not be modified because it is in use by application (/Common/t.app/t) that does not have a matching traffic group&nbsp;
Do you have the same error?&nbsp;

Thank you. I am able to reproduce it now. I added a traffic-group parameter directly into the iapp, which did not help by itself, but if you change the traffic-group to the same value in both in the iapp presentation and in the Template Selection section simultaneously, it works.
implementation
set static { ip-protocol tcp snat automap }
set vip ${::vs__vip}

iapp::conf create ltm virtual ${tmsh::app_name}_HTTP destination ${vip}:80 $static
iapp::conf create ltm virtual-address /Common/${vip} arp disabled route-advertisement enabled traffic-group $::vs__traffic_group

presentation
section vs {
    string vip
    choice traffic_group tcl {
        return [iapp::get_items cm traffic-group]
    }
}

If you would, please open a case with F5 Support and refer to ID636035.

Hi,&nbsp;
I just stumbled across this question when I hit exactly the same problem: I want to use an iApp for the mass deployment of VIPs that will be cloned to a second traffic group.&nbsp;
Running 12.1.2 it seems impossible to detach a virtual-server from the iApp (even though app-service none will hide the link to the application in the virtual address list, it seems the iApp itself does not forget about it...). Of course I could change the iApp to cover only one traffic group and replicate the config manually / scripted to the seconds traffic group but I really would like to get it solved using only a single iApp.&nbsp;
Do you see a potential other solution?&nbsp;
Thanks,
Sebastian&nbsp;
