In Oracle Solaris, a VXLAN endpoint is represented by a VXLAN datalink. This VXLAN datalink is associated with an IP address (IPv4 or IPv6) and a VXLAN network identifier (VNI). Even though multiple VXLAN datalinks can use the same IP address, the combination of the IP address and VNI must be unique. You can configure a VXLAN datalink with an optional multicast address, which is used for discovering the peer VXLAN endpoints on the same VNI and also to implement broadcast within a VXLAN segment. VXLAN datalinks in the same VNI must be configured with the same multicast address.
The convention for naming VXLAN datalinks is same as that for links or VLANs. For information about providing valid datalink names, see Rules for Valid Link Names in Configuring and Managing Network Components in Oracle Solaris 11.4.
