Which action would you use to connect two virtual switches that are configured on the same router?
Which action would you use to connect two virtual switches that are configured on the same router?
To connect two virtual switches configured on the same router, you must use an external cable. This is because virtual switches typically use the same MAC address as part of their bridge IDs in BPDUs, which causes spanning tree protocols not to function properly if internal logical configurations are used. Therefore, a physical connection with a cable is required to ensure proper communication between the virtual switches.
At some point you might want to interconnect the virtual routers and virtual switches that are local to a single chassis. For virtual routers, you can accomplish this task using either a logical tunnel interface or by looping two interfaces together with a single cable. For virtual switches, this process works only using the external cable method.
C is the correct answer: " For virtual routers, you can accomplish this task using either a logical tunnel interface or by looping two interfaces together with a single cable. For virtual switches, this process works only using the external cable method. "
C. For virtual routers, you can accomplish this task using either a logical tunnel interface or by looping two interface with a single cable. For virtual switches, this works only using external cable. Reason is spanning tree protocols do not function properly. Because all virtual switches use the same MAC address as part og their bridge ID in BPDUs. Virtual switch’s mac cannot be changed
The answer should be "A" routing instane has instance-type, Virtual switch. https://www.juniper.net/documentation/us/en/software/junos/multicast-l2/topics/topic-map/layer-2-virtual-switch-instances.html
The question is on how to connect two virtual switch instances. There are two methods: for layer 3, configure irb interface; for layer 2, connect physically. I'd go C
Answer is C, with a cable
Only with Cable, Virtual Switches uses the same MAC
Only with Cable
