This system e0/1 and the receive system e0/2 PC can be exchanged, but when each data
taken from a VLAN is different.
Data from the pc1, by inter0/1 pvid VLAN10 encapsulation VLAN10 labeled into switches,
switch found system e0/2 allows 10 data through the VLAN, so the data is forwarded to
the system e0/2, because the system e0/2 VLAN is untagged 10, then switches at this
time to remove packet VLAN10 tag, in the form of ordinary package sent to pc2, pc1 - > p2
is VLAN10 walking at this time.
Again to analyze pc2 gave pc1 package process, data from the pc2, by inter0/2 pvid
VLAN20 encapsulation VLAN20 labeled into switch, switch found system e0/1 allows
VLAN by 20 data, so the data is forwarded to the system e0/1, because the system e0/1
on the VLAN is untagged 20, then switches remove packets on VLAN20 tag at this time, in
the form of ordinary package sent to pc1, pc2 at this time - > pc1 is VLAN 20 .
