Configuring L2PT for VPLS

You can use Layer 2 Protocol Tunneling (L2PT) to transparently send packets across a VPLS network. The customer edge (CE) device sends and receives packets over VPLS pseudowires to and from the provider edge (PE) device. L2PT doesn't interfere with protocol instances in the network. L2PT supports 802.1x, 802.3ah, CDP, E-LMI, MVRP, LACP, STP/RSTP/MSTP, LLDP, MMRP, and VTP Layer 2 control protocols.

Here is how to configure L2PT for VPLS on the PE device.

  1. The packets leave the CE from an untagged or single-tagged port called interface CE-interface-name. Configure VPLS VLAN encapsulation for packets that arrive from this port.
    1. Enable flexible VLAN tagging and flexible Ethernet services so you can configure more than one instance of VPLS encapsulation on the port.
    2. Since the L2CP frames from the CE device are untagged, configure the native VLAN ID to support untagged VLAN packets.
    3. Configure VPLS VLAN encapsulation.
  2. Configure the routing instance.
    1. Configure VPLS as the routing instance protocol.
    2. (Optional) If your router doesn't have a Tunnel Services PIC, you will need to configure the no-tunnel-services statement at the [edit routing-instances routing-instance-name protocols vpls] hierarchy level.
    3. Configure the instance type and identify the CE port. Use the VLAN ID from Step 1.
  3. Configure the L2PT protocol. The protocol can be any of the following: (stp | vtp | cdp | ieee8021x | ieee8023ah | elmi | lacp | lldp | mmrp | mvrp).
You have configured L2PT for VPLS on your network.
