Reflective relay is a feature that enables VMs that are using the VNICs over the same physical NIC to communicate through the external switch. The switch must support this capability. In Oracle Solaris, LLDP is extended to include an EVB type-length value (TLV) unit, which is used to determine if the switch supports reflective relay capability and to enable or disable reflective relay capability on the switch. Therefore, you can automate the detection and configuration of this capability on the switch by using LLDP only if the switch supports LLDP and EVB TLV unit. Otherwise, reflective relay feature must be manually configured on the switch. For information about how to manually configure reflective relay, refer to the switch manufacturer's documentation.
