Just passed CCNA and am working on Security studies when a wild Private VLAN appeared.
I haven't heard of these before and am having trouble understanding the use cases this is good for. I have the "What it is" concept down but am hoping got get some answers to the Why and When questions to better understand this.
I think the answer to the Why question is for VLAN ID conservation and IP address conservation, but I dont see this being very realistic unless the use case is with an insane amount of customers/hosts. And that kinda answers the When question for me too.
Does anyone use Private VLANs IRL?
