Tier-0 system prefix lists do not match the configured value.

Products

• VMware NSX

Issue/Introduction

• System prefix lists on a newly created Tier-0 do not match the configured value.
• There was a Tier-0 with the same name in the past and it was deleted.
• The new Tier-0 system prefix list has the old deleted Tier-0 values.

Environment

VMware NSX-T Data Center

Cause

When a Tier-0 is deleted, the entry in corfu GenericPolicyRealizedResource (GPRR) table is not deleted, therefore when a Tier-0 is created again with the same name, the old GPRR entry is referenced and the new Tier0's system prefix list values are not reflected as configured.

Resolution

This issue is resolved in NSX-T 3.2.3 and NSX 4.1.1.

Impact/Risks:
