Symptoms:
- NSX-T environment prior to NSX 2.4.0
- ESXi host is configured for load balancing and has multiple TEP interfaces e.g. vmk10, vmk11, etc.
- GARP packets reach some VMs on an ESXi host but not others
Note: The impact of this issue is seen when an application VM is configured for HA.
On failover, a VIP becomes active on the standby VM and sends a GARP.
If a VM does not receive this GARP it can continue to send traffic to the VM which is no longer active.
