BGP Neighbor Stuck in "Deletion in Progress" State in Federation Environments

Products

• VMware NSX

Issue/Introduction

• Global Manager (GM) Status: BGP neighbor shows a persistent "Deletion in progress" status.

• Local Manager (LM) Status: The same neighbor appears as "Down" rather than being deleted.

• API Validation: A direct API query reveals the neighbor entry is marked with delete:true but carries a flag: "overridden at site", indicating a sync mismatch between the GM and LM.
  
  

Environment

VMware NSX

Cause

• The issue was caused by a configuration "override" at the Local Manager level in a Federation setup.
• This local override prevented the deletion command initiated at the Global Manager from successfully synchronizing and completing.
  
  

Resolution

Revert Operation: Perform a "Revert" operation from the Local Manager (LM). This action discards local overrides and forces the LM to align its configuration state with the Global Manager.

Steps to perform revert operation:

• Switch to respective Local Manager.
• Navigate to T0 Gateway > BGP neighbor > Click ⋮ "Revert"
  
  In NSX Federation, local overrides take precedence over global configs. Reverting the override allows the Global Manager's "delete" instruction to finally execute on the Local Manager.
