Configuring MX Series Router Cloud CPE Multiple Ethernet Interface Services—Extending Subscriber VLANs to the PE Router Using a Q-in-Q Tunnel

With the subscriber VLAN in a Q-in-Q tunnel, you do not need to be concerned about conflicting subscriber VLAN IDs between multiple customers. You can configure the Q-in-Q tunnel in the Layer 2 CPE or an aggregation switch.

Note:

This configuration uses one bridge domain and two subscriber VLANs from the Layer 2 CPE.

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.

Then complete the following tasks to configure the PE router and Layer 2 CPE or aggregation switch:

  1. Configure the PE router. See Configuring the PE Router for MX Series Router Cloud CPE Multiple Ethernet Interface Services (Q-in-Q Tunnel)
  2. Configure the Layer 2 CPE. See Configuring the Layer 2 CPE for MX Series Router Cloud CPE Multiple Ethernet Interface Services.
    Note:

    This procedure uses a Juniper Networks EX Series Ethernet Switch for the Layer 2 CPE.

  3. Configure the aggregation switch. See Configuring the Q-in-Q Tunnel on the Aggregation Switch (EX Series Ethernet Switch).
    Note:

    This procedure uses a Juniper Networks EX Series Ethernet Switch for the aggregation switch.
