Issue/Introduction

• In the Migrate configuration phase, task fails with following error:

  • Config translation failed [Reason: [TOPOLOGY] Can not proceed with migration: Northbound Edges in ECMP for a topology graph cannot have different Graceful restart BGP config. Please update and retry.]

Environment

VMware NSX for vSphere

VMware NSX

Cause

This error is thrown because Edges in ECMP have different graceful restart BGP configuration. For a successful Configuration migration, Graceful restart BGP configuration should be same. 

Resolution

Perform the following steps to ensure the Graceful restart configuration is uniform across Edges:

1. Log in to the vSphere Client.

2. Click Networking & Security > NSX Edges.

3. Double-click an NSX Edge.

4. Click Manage > Routing > BGP.

5. Next to BGP Configuration, click Edit.

6. Make the Graceful restart configuration uniform for Edges.
