Configuring EVPLAN Services (IEEE 802.1ad Bridge)

Configuring EVPLAN Services (IEEE 802.1ad Bridge)

The QinQ technology provides a cheap and easy solution for Layer 2 virtual private networks (VPNs). The IEEE 802.1ad bridge uses the QinQ technology to provide the VPN solution, thus facilitating the identifying, differentiating and grooming EVPLAN services.

Networking Diagram

A network operator requires that the voice over IP (VoIP) and high speed Internet (HSI) services sent to the transmission network be uniformly labeled and groomed at the convergence node.

Service Requirement

As shown in Figure 2-79, the transmission network is required to carry the VoIP and HSI services.

User requirements:

  • The VoIP services of user M and user N are sent to the transmission network at NE2 and NE4 respectively and to the VoIP server at the convergence node NE1. The services share a 20 Mbit/s bandwidth.
  • The HSI services of user M and user N are sent to the transmission network at NE2 and NE4 respectively and to the HSI server at the convergence node NE1. The services share a 40 Mbit/s bandwidth.
  • The VoIP services need to be isolated from the HSI services.
  • The data communication equipment of user M and user N provides 100 Mbit/s Ethernet electrical interfaces of which the working mode is auto-negotiation, and does not support VLAN.

    • C-VLAN ID of the VoIP services: 10
    • C-VLAN ID of the HSI services: 20
NOTE:

The application scenarios where one branch needs to communicate with other branches are as follows:

  • User M needs to communicate with user N.
  • User M need not communicate with user N.

If user M and user N need to communicate with each other, skip 1.e in which you change the Hub/Spoke attributes of ports connected to the bridge.

Requirement of the operator: The operator requires that all services received from the user side should be uniformly labeled and groomed through planned S-VLANs.

  • S-VLAN ID of the VoIP services: 100
  • S-VLAN ID of the HSI services: 200

NOTE:

This topic considers the OptiX OSN 550 as an example to describe the board layout. In the case of other products, the configuration method is the same, except for the slots. For the slot information, see the Hardware Description of the relevant product.

Board Configuration Information

For the EVPLAN (IEEE 802.1ad bridge) services supported by Ethernet switching boards, refer to Table 2-152.

In this example, the convergence node NE1 is configured with an EFS8 board that supports the IEEE 802.1ad bridge to implement EVPLAN services in which VoIP data is isolated from HSI data.

  • The VoIP services tagged with C-VLAN ID 10 from NE2 and NE4 are further tagged with S-VLAN ID 100 when they arrive at the IEEE 802.1ad bridge of NE1. Then, the services are forwarded to the VoIP server through Layer 2 switching.
  • The HSI services tagged with C-VLAN ID 20 from NE2 and NE4 are further tagged with S-VLAN ID 200 when they arrive at the IEEE 802.1ad bridge of NE1. Then, the services are forwarded to the HSI server through Layer 2 switching.

The access nodes NE2 and NE4 each are configured with an EGT1 board. The EPL services are configured to implement transparent transmission from NE2 and NE4 to NE1.

Signal Flow and Timeslot Allocation

The services of user M and user N are transmitted from the access nodes NE2 and NE4 respectively to the convergence node NE1 through the Ethernet transparent transmission boards. VoIP and HSI services carrying different C-VLAN IDs are tagged with different S-VLAN IDs. The service data is isolated and exchanged at Layer 2 through S-VLAN filtering.

Figure 2-80 shows the signal flow of the EVPLAN services (IEEE 802.1ad bridge) and the timeslot allocation to the EVPLAN services (IEEE 802.1ad bridge).

For the method of calculating the bandwidth of the Ethernet services carried by a VCTRUNK, see Ethernet Service Bandwidths Carried by VCTRUNKs of Ethernet Boards.

Configuration Process (Configuration on a Per-NE Basis)

An EVPLAN service (IEEE 802.1ad bridge) and the corresponding S-VLAN filtering table need to be created for the convergence node NE1. The access nodes NE2 and NE4 need to be configured with EPL transparent transmission services only.

Prerequisites

You must be familiar with Flow of Configuring EPL Services.

Background Information

If the Ethernet switching boards in the actual application scenarios are different from the boards in this example, you need to learn about the requirements for configuring specific boards.

The IEEE 802.1ad provider bridge supports ports with the C-Aware and S-Aware attributes only.

The C-Aware ports are used to add and strip the S-VLAN tags. The S-Aware ports are used to transparently transmit the S-VLAN tag.

The IEEE 802.1ad provider bridge supports the following operation types:

  • Adding the S-VLAN tag based on the port
  • Adding the S-VLAN tag based on the port and C-VLAN
  • Performing port mounting based on the port
  • Performing port mounting based on the port and the S-VLAN

This topic describes the four operation types when Bridge Switch Mode of the IEEE 802.1ad provider bridge is set to IVL/Ingress Filter Enabled.

  • Adding the S-VLAN based on the port: The packets that enter the C-Aware port are added with the preset S-VLAN tag, and are forwarded in the bridge according to the S-VLAN filtering table. Before the packets leave the C-Aware port, the S-VLAN tag is stripped.
  • Adding the S-VLAN tag based on the port and C-VLAN: The entry detection is performed for the packets that enter the C-Aware port. Then, the corresponding S-VLAN tags are added to the packets according to the mapping relation between the C-VLAN tags and the S-VLAN tags of the packets. If the mapping relation does not exist, the packets are discarded. After the S-VLAN tags are added, the packets enter the bridge, where the packets are forwarded according to the S-VLAN filtering table. Before the packets leave the C-Aware port, the S-VLAN tag is stripped.
    NOTE:
    • The same C-Aware port supports different C-VLAN tags being mapped to different S-VLAN tags, but does not support the same C-VLAN tag being mapping to multiple S-VLAN tags.
  • Performing port mounting based on the port: The packets that enter the S-Aware port are not filtered. Instead, the S-VLAN switch is performed directly. The packets must have the S-VLAN tags. Otherwise, the packets are discarded. When the packets leave the S-Aware port, the packets are transparently transmitted.
  • Performing port mounting based on the port and the S-VLAN: The entry filtering is performed according to the preset S-VLAN tag. The packets that do not belong to the S-VLAN are discarded. Then, the packets are forwarded according to the S-VLAN filtering table. When the packets leave the S-Aware port, the packets are transparently transmitted.

In the case of the four operation types, the following conditions must be met before the packets leave a port:

  • The port is contained in the S-VLAN filtering table that is created by the user.
  • The S-VLAN ID corresponding to the port must be specified when the user manually mounts the port to the bridge.
    • In the case of a C-Aware port, the S-VLAN ID corresponding to the port is the S-VLAN ID that is added when the packets enter the port.
    • In the case of an S-Aware port, the S-VLAN ID corresponding to the port is the S-VLAN ID that is set when the user mounts the port to the bridge. If the S-Aware port is mounted based on the port, the S-VLAN ID is considered to contain all the legal S-VLAN IDs.

        Sink VC4 VC4-1 In this example, VC4-1 is specified as the VC-4 timeslot of the Ethernet service on the line board.
        Sink Timeslot Range(e.g.1,3-6) 1-30 The value range of the sink timeslots can be the same as or different from the value range of the source timeslots. The number of source timeslots must be, however, the same as the number of sink timeslots.

  2. Configure the EPL services on NE2 and NE4.

    NOTE:
    The Ethernet services of NE2 and NE4 are point-to-point transparent transmission services. See Configuring EPL Services on an Ethernet Transparent Transmission Board to set the parameters.

  3. Enable the performance monitoring function of the NEs. For details, see Setting Network-Wide Performance Monitoring.
  4. Back up the configuration data of the NEs. For details, see Backing Up the NE Data to the System Control Board.
Relevant Task

If the services are configured incorrectly and thus need to be deleted, see Deleting EVPLAN Services.
