Very clear explanation of an important network security topic. Liked & subscribed.

Excellent content. Question: How would an attacker know which VLAN has trunks configured to different VLANs? And how would an attacker be able to send information from their device specifically to that other VLAN?

[陈瀚龙]

So, if the packet didn't contain the outside tag with the native vlan on it, and only the tag of the intended target, THAT tag would be removed by the native vlan and the packet would go nowhere further than the native vlan, correct? There's no more direct approach to the intended vlan than via the native vlan?

Is the TAG in Double Tagging here the same as the “VLAN HEADER” mentioned in earlier videos ?
