Virtual Switches on MX Series Devices

AB

Virtual switches on MX Series devices are used to provide Layer 2 bridging and switching functions in a virtualized environment. Here are the two valid statements for virtual switches on MX Series devices:

A. Integrating routing and bridging (IRB) interfaces are supported: This means that virtual switches on MX Series devices can be configured with IRB interfaces, which combine Layer 2 bridging and Layer 3 routing functions in a single interface. This allows for flexible and efficient network design, as well as simplifying the management of the virtualized environment.

B. Layer 2 interfaces are supported: Virtual switches on MX Series devices support Layer 2 interfaces, which enable connectivity between devices at the data-link layer. This allows for the creation of Layer 2 domains, which can span multiple physical devices and provide seamless connectivity between virtual machines or containers.

C. Interfaces are inherently loop-free: This statement is not valid. Virtual switches on MX Series devices can create loops if they are not configured correctly. To prevent loops, Spanning Tree Protocol (STP) or other loop prevention mechanisms should be used.

D. Trunk interfaces are not supported: This statement is not valid. Virtual switches on MX Series devices do support trunk interfaces, which allow for the transmission of multiple VLANs over a single physical link. Trunk interfaces are commonly used in virtualized environments to provide connectivity between virtual machines or containers that are on different VLANs.

In summary, the two valid statements for virtual switches on MX Series devices are that they support IRB interfaces and Layer 2 interfaces. It is important to note that loops can occur if not configured correctly and that trunk interfaces are supported.
