Issue/Introduction

++ Edge will receive an invalid IP "0.0.0.0" from VCO when domestic preference flag is selected for Zscaler IPSEC tunnel Automation.

++ Under VCO > Monitor > network services > CSS profile, we can observe Zscaler peer IP as "0.0.0.0"

Environment

All SDWAN VECO software versions

Cause


After the launch of the Domestic Preference feature, users have noticed differing behaviors between GRE and IPsec endpoints.

For GRE endpoints, when domestic preference is enabled, Zscaler provides available in-country endpoints. If there are none or only one available, it adds a nearby endpoint from outside the country.

In contrast, when the same is configured for an IPsec endpoints and there are none or only one available, the response includes 0.0.0.0 addresses for the unavailable items.

 

Resolution

As a workaround, please disable the "domestic preference" flag in the CSS tunnel configuration for IPsec and save the changes.

For a permanent resolution, an enhancement request has been submitted to Engineering and is being tracked under #149289.
