Explanation
In Cisco FTD Integrated Routing and Bridging (IRB), a Bridge Virtual Interface (BVI) is the logical Layer 3 interface assigned to a bridge group. The BVI acts as the gateway for all members of the bridge group and is the point through which bridged traffic communicates with routed interfaces. A switch virtual interface is an IOS/IOS-XE concept, bridge group member interfaces are the physical ports within the group, and subinterfaces serve VLAN trunking-not bridge-to-routed communication.
