Configuring MX Series Router Cloud CPE Multiple Ethernet Interface Services—Extending Subscriber VLANs to the PE Router (One Bridge Domain per VLAN)

This procedure configures one bridge domain and one IRB interface per subscriber VLAN. Each bridge domain has one Layer 2 interface. The IRB interface is configured with the IP address matching the subnet of the VLAN. Using multiple bridge domains effectively creates a separate broadcast domain for each VLAN. You also need to configure a VRF routing instance for the VPN site and reference the IRB (one for each subscriber VLAN) as the interface.

Note:

To avoid VLAN ID conflicts between subscribers, you can configure VLAN ID translation on the Layer 2 CPE or the aggregation router.

Before you begin, make sure you have completed the steps for the cCPE common configuration. See Configuring the Common Configuration for MX Series Router Cloud CPE Services.

In this procedure you configure two VLANs for the subscriber and one bridge domain and one IRB interface per VLAN. You also need to configure a VRF routing instance for the subscriber VPN site and reference each of the IRB interfaces (one for each subscriber VLAN) as the interface.

Complete the following tasks to configure the PE routers and Layer 2 CPE:

  1. Configure the PE router. See Configuring the PE Router for MX Series Router Cloud CPE Multiple Ethernet Interface Services (One Bridge Domain per VLAN).
  2. Configure the Layer 2 CPE. This procedure uses a Juniper Networks EX Series Ethernet Switch for the Layer 2 CPE. See Configuring the Layer 2 CPE for MX Series Router Cloud CPE Multiple Ethernet Interface Services.
