Virtual switches are an essential part of network virtualization that provide the ability to create multiple logical switches on a single physical switch. Below are the two statements that are true about virtual switches:
A. Multiple virtual switches share a single MAC table: When a virtual switch is created, it is associated with a virtual router or an integrated routing and bridging (IRB) interface. Each IRB interface has a separate MAC address, and each virtual switch maintains a separate MAC table that maps MAC addresses to their corresponding virtual ports. However, multiple virtual switches can share a single MAC table to avoid MAC address duplication and improve efficiency.
B. Virtual switches contain separate MAC tables: While multiple virtual switches can share a single MAC table, each virtual switch still maintains its own separate MAC table. This separation ensures that each virtual switch has a unique set of MAC addresses that it can use to communicate with its virtual ports and other devices on the network.
C. By default, the direct route associated with a virtual switch's IRB interface is placed in inet.0: The IRB interface provides a logical interface that connects the virtual switch to the physical network. By default, the direct route associated with the IRB interface is placed in the inet.0 routing table, which is used for unicast IP forwarding.
D. By default, the direct route associated with a virtual switch's IRB interface is placed in the associated virtual switch's routing table: This statement is false. The direct route associated with the IRB interface is placed in the inet.0 routing table, not in the associated virtual switch's routing table. The virtual switch's routing table is used for the routing of multicast and broadcast traffic and is not directly related to the IRB interface.
