Scenario: Establishing L2 connectivity between CPE devices

You can establish L2 connectivity between CPE devices for the following purposes:

• Creating an L2 domain that includes multiple remote locations.
• Transmitting L2 traffic for keepalive links between CPE devices installed at different remote locations.
• Implementation of custom traffic mirroring scenarios.

The scenario for establishing L2 connectivity between CPE devices involves the following steps:

1. Creation of OpenFlow ports on virtual switches of CPE devices

1. When creating or editing a network interface without an IP address on CPE devices between which you want to establish L2 connectivity, select the L2 mode check box. When the check box is selected, an OpenFlow port mapped to the network interface is automatically created on the virtual switch of the CPE device. This check box is cleared by default. You cannot select this check box in the following cases:
   • You selected the following check boxes when creating a network interface:
     • Bridge
     • NetFlow
     • Force IP, route, and gateway
   • The network interface is used in a static route.
   • The network interface is used by BGP.
   • The network interface is used by the OSPF protocol.
   • The network interface is used by the VRRP protocol.
   • The network interface is used to transmit multicast traffic.
   • The network interface is used by a virtual routing and forwarding table (VRF).
   • The network interface is used for CPE device diagnostics using the ping, traceroute, tcpdump, and/or sweep utility.

   Number of the OpenFlow port automatically created on the virtual switch of the CPE device is displayed in the OpenFlow port field. You can change the OpenFlow port number. Range of values: 11 to 20.

1. Creating service interfaces mapped to OpenFlow ports

   Create service interfaces mapped to OpenFlow ports that were automatically created at the previous step of this scenario. You must select the OpenFlow port that the service interface is mapped to in the Port drop-down list.

2. Adding service interfaces to the transport service

   Add the service interfaces that you created at the previous step of this scenario to the transport service that you want to use to establish L2 connectivity between CPE devices. You can use the following instructions to complete this step:

   • Creating a P2P service and Editing a P2P service.
   • Creating a P2M service and Editing a P2M service.
   • Creating a M2M service and Editing a M2M service.
   • Creating an L3 VPN service and Editing an L3 VPN service.
   • Creating an IP multicast service and Editing an IP multicast service.
   • Creating a TAP service and Editing a TAP service.

L2 connectivity between CPE devices is established.
