## Symptoms

- After deleting a global policy assignment, some Virtual Systems (VSs) drop traffic that previously passed successfully.  
This happens when:

* The global policy contains global network objects.
* In SmartConsole, the user configured the affected VSs to **Calculate topology automatically based on routing information**.
* On the Local Domain, the user configured the affected VSs to use IP addresses that belong to global network objects.

<br />

## Cause

Removing the global policy assignment does not remove the reference to the Global Domain network objects. This results in unexpected Anti-Spoofing drops.
