    L2K (Layer2-Kompella) VPN

    The L2K (Layer2 Kompella) VPN, based on the IETF Kompella draft, is implemented by Juniper only. To configure a L2K VPN, the user would perform the following sequence of steps:

    1. Bring up the Add VPN window and selecting Layer 2 Kompella. Then type in a name for the VPN (e.g. L2Kompella_3).
    2. Click on Next to bring up the Common Properties window where you can assign the Route Distinguisher, Route Target Exports, and Route Target Imports for the chosen AS and PEs. The program automatically recommends values based on the chosen AS or you may provide your own.

    3. Click on Next to bring up the following window where you would identify PEs and assign the PE facing CE interfaces (in the same manner as described under the L3 (Layer 3) VPN section). The following figure shows the result of the assignment of the interfaces.
