Environment

All NSX Networking versions

Cause

After gateway connectivity is toggled, L3 routing domain is not linked to the bridged segment.

RARP packets are not sent to the host Transport Nodes and MAC table on the hosts are not updated with new active edge TEP.

Resolution

This issue is resolved in VMware NSX 4.2.1, available at Broadcom downloads.

If you are having difficulty finding and downloading software, please review the Download Broadcom products and software KB.

 

Workaround:

To avoid connectivity issue, refrain from toggling gateway connectivity.

To recover from connectivity issue after failover, restart dataplane service on edge CLI. 

> restart service dataplane

NOTE: Restarting dataplane service impacts datapath.
