Understanding and Configuring VLAN-based Layer 2 User Bridging

Understanding and Configuring VLAN-based Layer 2 User Bridging

Layer 2 user bridging implements Layer 2 data exchange among users under the same MA5800.

Overview

Users under the same MA5800 are isolated at Layer 2, but QinQ service deployment requires users communicate with each other at Layer 2. Therefore, QinQ services can be deployed only between different MA5800s.

If users in the same IP network segment on the same MA5800 need to exchange data, upstream equipment should support ARP proxy to implement Layer 3 data forwarding.

The Layer 2 user bridging feature addresses the preceding issues. After Layer 2 user bridging is enabled, users under the same MA5800 can exchange data at Layer 2.

Principles

OLT supports VLAN-based Layer 2 user bridging.

VLAN-based Layer 2 User Bridging

Figure 1-1 VLAN-based Layer 2 user bridging model

As shown in Figure 1-1, the following functions are implemented on the MA5800 after Layer 2 user bridging is enabled on a VLAN.

  • Inter-board user bridging: bridging among ports on different boards, for example, users 1, 2, and 3 can exchange data with users 4 and 5
  • Intra-board user bridging:
    • Bridging among different users under the same port, for example, users 1 and 2 can exchange data with each other
    • Bridging among users under different ports on the same board, for example, users 1, 2, and 3 can exchange data
    • Bridging among different ports on the same board, for example, users 4 and 5 can exchange data with each other
Figure 1-2 VLAN-based user bridging network

As shown in Figure 1-2, on one MA5800, Layer 2 bridging is implemented among enterprise private line users (VPN represented by the red line) but is not implemented among some common access users (represented by the green line). Services are classified by VLAN. VLAN 2 is a QinQ VLAN for carrying enterprise private line services. Enable Layer 2 user bridging on VLAN 2 so that private line users on the same MA5800 can exchange data.

Configuring VLAN-based Layer 2 User Bridging

Default Setting

By default, Layer 2 user bridging based on VLAN service profiles is disabled.

Procedure

  1. In global configuration mode, run the vlan service-profile command to enter the VLAN service profile mode.
  2. Run the user-bridging command to enable Layer 2 user bridging on a VLAN service profile.
  3. Run the commit command for the settings to take effect.
  4. Go back to the global configuration mode and run the vlan bind service-profile command to bind a VLAN to the VLAN service profile.

    NOTE:
    If the VLAN has been bound to the VLAN service profile, you do not need to bind the VLAN again.

Result

If you run the display vlan service-profile command, User-bridging is enable for the VLAN service profile. Then, under the MA5800, users in the same VLAN with Layer 2 user bridging enabled can be pinged with each other

Example

Example: VLAN 10 is the S-VLAN for enterprise private line services. The VLAN is bound to VLAN service profile 3. Run the following commands to enable Layer 2 user bridging on VLAN 10 so that users in the VLAN on the same MA5800 can communicate with each other at Layer 2.

huawei(config)#vlan service-profile profile-id 3
huawei(config-vlan-srvprof-3)#user-bridging enable
huawei(config-vlan-srvprof-3)#commit
huawei(config-vlan-srvprof-3)#quit
