In Layer 2 zone configuration, typically, you can add VLAN interfaces. VLAN interfaces allow for the segmentation of a single physical network into multiple virtual networks, enabling better network management and security. These interfaces are associated with specific VLAN IDs and provide connectivity within their respective VLANs. While route interfaces are used for Layer 3 routing, virtual interfaces are more commonly associated with virtualization technologies, and mirror interfaces are utilized for traffic monitoring and analysis purposes, making VLAN interfaces the most suitable option for adding to Layer 2 zones.
