Traceflow diagram includes hops not traversed by the actual traffic

Products

• VMware NSX

Issue/Introduction

Symptoms:

• When running a traceflow between 2 VMs, the diagram displays hops which are not traversed.
• The data path section shows the correct hops taken.
• The traceflow source and destination VMs are on two separate segments and are connected to a Tier-1 Logical router.
• The Tier-1 Logical router is connected to a Tier-0 Logical router.
• One of the two segments is also connected to a second Tier-1 via a service interface.
  
  

Environment

VMware NSX-T Data Center

Cause

If a segment is connected to two Tier-1 routers and one of the those Tier-1 routers is connected to a parent Tier-0, the logic to find the correct hierarchy for the same segment fails.

Resolution

The issue is resolved in NSX-T 3.0.3 onwards
