Changes made to the route redistribution on a stretched logical router on one site simultaneously affects the other site

Products

• VMware NSX

Issue/Introduction

When configuring Route Redistribution on a stretched Tier-0 gateway, enabling settings for a specific site (e.g., "Test") unintentionally applies the same settings to other sites that contain the first site's name as a prefix (e.g., "Test.Test-2"). This affects both the enabling of redistribution and the configuration of Redistribution Rules.

Environment

VMware NSX

Cause

The UI logic appears to identify target sites using a partial string match (prefix match) rather than an exact string match.

Resolution

The issue is addressed in NSX 9.1 and 4.2.4 

Additional Information

To update GM Tier-0 Route Redistribution and Route Redistribution use the below APIs.

Step 1. Get the Tier-0 Local Services
GET: https://<policy-mgr>/global-manager/api/v1/global-infra/tier-0s/<tier-0 id>/locale-services/

Step 2. Get the specific Tier-0 Local Services which you wish to udpate
GET: https://<policy-mgr>/global-manager/api/v1/global-infra/tier-0s/<tier-0 id>/locale-services/<locale-services-id>

Copy this GET API request response we will use it in Step 3.


Step 3: Update Tier-0 Locale Service with Route Redistribution and Rules

PUT https://<policy-mgr>/global-manager/api/v1/global-infra/tier-0s/<tier-0 id>/locale-services/<locale-services-id>
