If the device is completely in a standby mode, it does not process VXLAN traffic.


The standby device does not process VXLAN traffic.


An HA pair is configured with VXLAN tunnels and requires processing of VXLAN traffic on the standby device.



Fix Information

A new BigDB variable iptunnel.configsync controls the ConfigSync behavior on the standby device. If the variable is set to 'disable', the tunnel objects are not synchronized across the HA pair which allows setting the local address of the tunnel to a non-floating self address. The user has to configure the tunnel objects on both the active and the standby devices. This enables both devices to process VXLAN traffic. Note: The variable needs to be modified on both the active and the standby devices prior to creating any tunnels. By default, the variable is set to 'enable'.
