Hi there,
I hope this forum is ok for posts like this in which I ask for clearance in a topic...
So in order to send a packet between vlans i understand we need to change the switchport to trunk, But what is actually happening "behind the scenes" when I do that ?
Is the switch tagging the packet with the source vlan or the destination vlan ?
And what am I expected to do at work when such need occurs ? Do I need to revert it after the the sides communicated or It expires automatically ? I mean if the connection is temporary and I'll have 200 VLANs I could be all day encapsulating and reverting it ....
Thanks, Eli

" and even then, if you had multiple switches, you might have a router routing between them "
But isn't it super-unefficient ? Sounds like a waste of ports.
"However, another option would be to have one interface on the router to connect to each VLAN."
I must have misunderstood that, isn't routers have usually like 2-3 ports meant for connecting to switches(/devices) only ?
"the router depends on IP addressing to decide where a packet should be directed to a particular interface"
Got it finally, i think :)
