I have a question regarding the way trunks operate in an environment where all the switches are in transparent mode.
Image the following scenario.
You have 4 switches trunked in the following configuration. A connects to B -> Connects to C -> connects to D
SwitchA---SwitchB---SwitchC---SwitchD
If Switch A and D have vlans 10, 11, and 12 configured, but B and C do not have these vlans configured. Will the traffic for these vlans be able to get from Switch A to D? Or would the switches between them, B and C need these vlans configured on them?
