Hi,guys,
I was just wondering a simple question,maybe stupid.Suppose a switch has
two ports belonging to vlan 1 and vlan 2 , seperately. When this
switch receives a frame from port 1, which belong to vlan 1, and destinate
to vlan 2, which is at port 2.How dose the swich know it cann't do this
directly(send to port 2) and must send it first to router and then come back
to port 2?
