Static routes on Tier 1 logical router added by AVI load balancer when restarting a virtual server are in pending state

Products

• VMware NSX

Issue/Introduction

• AVI Load Balancer is configured with NSX.
• The Tier 1 has static routes added for the virtual server.
• Creating a new virtual server in AVI works.
• If the virtual server is restarted in AVI, it goes into a failed state.
• Static in the cli of the AVI Service Engine (SE) shows the error:

Route update failed on <Virtual server name>

• The UI shows:

An object with the same path=[/infra/tier-1s/########-710c-4c92-9e15-############/static-routes/####-vsvip-########-70a2-4a97-93af-############-1-32] is marked for deletion. Either use another path or wait for the purge cycle (max 5 minutes) for permanent removal of the object.

• In NSX-T when we check the Tier 1 and look at the static routes, there are multiple routes in pending state and some of these a duplicates of each other.
