Introduction

This document provides examples for using VLAN tagging features to extend customer VLANs (CVLANs) across an Ethernet service provider network.

VLAN tagging features enable service providers to separate or aggregate customer traffic in the service provider network. The following are available VLAN tagging operations:

·     Adding a layer of service provider VLAN (SVLAN) tag.

·     Modifying the SVLAN tag, CVLAN tag, or both.

To add an SVLAN tag, use one of the following VLAN tagging features:

·     One-to-two VLAN mapping—Adds different SVLANs for traffic with different CVLAN tags.

·     Zero-to-two VLAN mapping—Adds double VLAN tags to untagged packets.

·     Two-to-three VLAN mapping—Adds an outermost VLAN tag to double-tagged packets.

·     Policy-based VLAN manipulation—Uses QoS nest actions in a QoS policy to tag different classes of frames with different SVLAN tags. Traffic classifiers include CVLAN ID, IP address, and MAC address. In addition, you can use QoS priority marking to set the 802.1p priority in SVLAN tags.

To modify VLAN tags, use one of the following VLAN tagging features:

·     VLAN mapping—Includes the following features:

¡     One-to-one VLAN mapping—Replaces one VLAN tag with another.

¡     Many-to-one VLAN mapping—Replaces multiple VLAN tags with the same VLAN tag.

¡     Two-to-two VLAN mapping—Replaces the SVLAN ID, CVLAN ID, or both IDs for an incoming double-tagged frame.

·     Policy-based VLAN manipulation—Uses a QoS policy to modify the CVLAN or SVLAN ID by using the remark service-vlan-id action.

The devices in the service provider network learn MAC addresses of CVLANs into the MAC address table of the SVLAN.

Prerequisites

The configuration examples in this document were created and verified in a lab environment, and all the devices were started with the factory default configuration. When you are working on a live network, make sure you understand the potential impact of every command on your network.

This document assumes that you have basic knowledge of VLAN mapping, QoS nesting, and QoS priority and VLAN marking.

Example: Configuring one-to-two VLAN mapping

Network configuration

As shown in Figure 1:

·     Customer A and Customer B each have two branches that require Layer 2 connectivity over the service provider network.

·     Both customers have three types of traffic. For each customer, the service provider assigns one SVLAN by traffic type.

Configure one-to-two VLAN mapping on each customer-side port of PE A and PE B to meet the following requirements:

·     The service provider adds an SVLAN tag to packets from customer networks based on the traffic type, as described in Table 1 and Figure 2.

·     The SVLAN tag uses the same 802.1p priority as the CVLAN tag.

Figure 1 Network diagram

Table 1 VLAN mapping table

Figure 2 Required traffic pattern in the service provider network

Analysis

To support multiple SVLANs and send traffic to the customer networks with the SVLAN tag removed, perform the following tasks on the customer-side ports:

1.     Configure the link type of the ports as hybrid.

2.     Assign the ports to the SVLANs as untagged VLAN members.

For the SVLAN tag to use the same 802.1p priority as the CVLAN tag, configure the customer-side port to use the 802.1p priority in incoming packets for priority mapping.

Software versions used

Table 2 shows the software versions used in this configuration example.

Table 2 Product and software version compatibility

Restrictions and guidelines

When you configure ports on the forwarding path of double-tagged packets across the service provider network, follow these restrictions and guidelines:

·     Set the MTU to a minimum of 1504 bytes for each port.

·     Configure all ports to allow double-tagged packets to pass through without removing the SVLAN tag.

By default, interfaces on the device are disabled (in ADM or Administratively Down state). To have an interface operate, you must use the undo shutdown command to enable that interface.

Example: Configuring QoS policies for SVLAN tagging

Network configuration

As shown in Figure 3:

·     Customer A and Customer B each have two branches that require Layer 2 connectivity over the service provider network.

·     The three types of traffic require separate transmission through three VLANs provided by the service provider. The service provider network configures different transmission policies for each type of traffic.

Apply a QoS policy to each customer-side port on PE A and PE B to separate the traffic by customer and traffic type.

Figure 3 Network diagram

Table 3 shows the VLAN assignment. For each customer, the service provider assigns one SVLAN by traffic type. Figure 4 shows the expected traffic transmission pattern after the QoS policies are applied to customer-side ports.

Table 3 VLAN assignment

Figure 4 Expected traffic pattern in the service provider network

Analysis

For the customer-side ports to support multiple SVLANs and send traffic to the customer site with the SVLAN tag removed, you must perform the following tasks:

1.     Configure the link type as hybrid on the customer-side ports.

2.     Assign the ports to the SVLANs as untagged VLAN members.

By default, the 802.1p priority in the SVLAN tag added by a port depends on the priority trust mode on the port.

·     If the 802.1p priority in frames is trusted, the device copies the 802.1p priority in the CVLAN tag to the SVLAN tag.

·     If port priority is trusted, the port priority is used as the 802.1p priority in the SVLAN tag. For untagged incoming frames, the port encapsulates the port priority as the 802.1p priority in the SVLAN tag.

To add SVLAN tags for traffic of different types, you can perform one of the following tasks on the customer-side ports:

·     Configure an SVLAN tagging QoS policy.

·     Configure one-to-two VLAN mapping.

Software versions used

Table 4 shows the software versions used in this configuration example.

Table 4 Product and software version compatibility

Restrictions and guidelines

For frames to travel across the service provider network, follow these restrictions and guidelines:

·     Set the MTU to a minimum of 1504 bytes for each port on the path of frames. This value is the sum of the default Ethernet interface MTU (1500 bytes) and the length (4 bytes) of a CVLAN tag. The CVLAN tag of frames is treated as part of the payload during transmission.

·     Configure all the ports on the forwarding path to allow frames from VLANs 1001 through 1003 and VLANs 2001 through 2003 to pass through without modifying or removing the VLAN tag.

By default, interfaces on the device are disabled (in ADM or Administratively Down state). To have an interface operate, you must use the undo shutdown command to enable that interface.

Example: Configuring one-to-one and many-to-one VLAN mapping

Network configuration

As shown in Figure 5:

·     Each household subscribes to PC, VoD, and VoIP services.

·     On the home gateways, PC, VoD, and VoIP service traffic is assigned to VLANs 1, 2, and 3, respectively.

To isolate traffic of the same service type from different households, configure one-to-one VLAN mapping on the wiring-closet switches. This feature assigns one VLAN to each type of traffic from each household.

To save VLAN resources, configure many-to-one VLAN mapping on the campus switch (Switch C). This feature transmits the same type of traffic from different households in one VLAN. Use VLANs 501, 502, and 503 for PC, VoD, and VoIP traffic, respectively.

Table 5 VLAN mapping scheme for each service

Figure 5 Network diagram

Software versions used

Table 6 shows the software versions used in this configuration example.

Table 6 Product and software version compatibility

Restrictions and guidelines

By default, interfaces on the device are disabled (in ADM or Administratively Down state). To have an interface operate, you must use the undo shutdown command to enable that interface.

Example: Configuring two-to-two VLAN mapping

Network configuration

As shown in Figure 6:

·     A company assigns its branch sites (Site 1 and Site 2) to VLAN 10, and the headquarters provides services in VLAN 30.

·     Service provider A uses SVLAN 100 to transmit VLAN 10 traffic for the branch sites.

·     Service provider B uses SVLAN 200 to transmit VLAN 30 traffic for the headquarters.

Configure two-to-two VLAN mapping to permit the two branch sites to access VLAN 30 of the headquarters without changing their VLAN assignment.

Software versions used

Table 7 shows the software versions used in this configuration example.

Table 7 Product and software version compatibility

Restrictions and guidelines

Configure two-to-two VLAN mapping on one of the edge devices between the two service provider networks. This example uses Switch C.

By default, interfaces on the device are disabled (in ADM or Administratively Down state). To have an interface operate, you must use the undo shutdown command to enable that interface.
