Figure 33 BPDU tunneling implementation 
 
 
The upper section of Figure 33 represents the service provider network (ISP network). The lower section, 
including User A network 1 and User A network 2, represents the customer networks. Enabling BPDU 
tunneling on edge devices (PE 1 and PE 2) in the service provider network allows BPDUs of User A 
network 1 and User A network 2 to be transparently transmitted through the service provider network. 
This ensures consistent spanning tree calculation...

Configuration restrictions and guidelines 
•  Settings made in Layer 2 Ethernet interface view  or Layer 2 aggregate interface view take effect 
only on the current port. Settings made in port group  view  take  ef fe ct on al l  por ts  i n the  por t g roup.  
•   Before you enable BPDU tunneling for DLDP, EOAM, GVRP, HGMP, LLDP, or STP on a port, disable 
the protocol on the port first.  
•   Because PVST is a special STP protocol, you must do two things before you enable BPDU tunneling  
for...

To configure destination multicast MAC address for BPDUs:  
Step Command Remarks 
1.  Enter system view. 
system-view  N/A 
2.  Configure the destination 
multicast MAC address for 
BPDUs.  bpdu-tunnel tunnel-dmac 
mac-address  
Optional. 
0x010F-E200-0003 by default. 
 
 
NOTE: 
For BPDUs to be recognized, the destination mult icast MAC addresses configured for BPDU tunnelin
g must
be the same on the edge devices  on the service provider network.

Configuring VLANs 
Overview 
Ethernet is a network technology based on the Carrier Sense Multiple Access/Collision Detect 
(CSMA/CD) mechanism. Because the medium is shared, collisions and excessive broadcasts are 
common on Ethernet networks. To address the issue,  virtual LAN (VLAN) was introduced to break a LAN 
down into separate VLANs. VLANs ar e isolated from each other at Layer 2. A VLAN is a bridging 
domain, and contains all broadcast traffic within it.

The Ethernet II encapsulation format is used here. Besides the Ethernet II encapsulation format, Ethernet 
also supports other encapsulation formats, including 802.2 LLC, 802.2 SNAP, and 802.3 raw. The 
VLAN tag fields are added to frames encapsulated in these formats for VLAN identification. 
In the header of a traditional Ethernet data frame, the field after the destination MAC address and the 
source MAC address is the Type field, which indi cates the upper layer protocol type, as shown in...

This chapter covers port-based VLAN, MAC-based VLAN, protocol-based VLAN, and IP subnet-based 
VLAN. The port-based VLAN implementation is the basis of all other VLAN implementations. To use any 
other VLAN implementations, you must configure port-based VLAN settings.  
You can configure all these types of VLANs on a port at the same time. When the switch is determining 
which VLAN a packet that passes through the port shou ld be assigned to, it looks up the VLANs in the 
default order of MAC-based...

Configuring basic settings of a VLAN interface 
For hosts of different VL ANs to communicate, you must use a router or Layer 3 switch to perform Layer 3 
forwarding. You use VLAN interfaces to achieve this.  
VLAN interfaces are virtual interfaces used for Layer 3 communication between different VLANs. They do 
not exist as physical entities on devices. For each VLAN, you can create one VLAN interface. You can 
assign the VLAN interface an IP address and specify it as the gateway of the VLAN to...
