Virtual Local
Area Network
(VLAN)
VLAN is a protocol proposed to solve broadcast and security issues for
Ethernet. It divides devices in a LAN into different segments logically
rather than physically, thus implementing multiple virtual work groups
which are based on Layer 2 isolation and do not affect each other.
VLAN
mapping
VLAN mapping is mainly used to replace the private VLAN Tag of the
Ethernet service packet with the ISP's VLAN Tag, making the packet
transmitted according to ISP's VLAN forwarding rules. When the packet
is sent to the peer private network from the ISP network, the VLAN Tag
is restored to the original private VLAN Tag according to the same
VLAN forwarding rules. Thus, the packet is sent to the destination
correctly.
