EVPN Virtual Private Wire Service (VPWS) is a Layer 2 VPN technology that uses MP-BGP for BGP EVPN route advertisement in the control plane and MPLS for forwarding in the data plane. EVPN VPWS provides point-to-point forwarding services for users by using ACs and PWs associated with cross-connects without MAC address table lookup.

EVPN VPWS network model

As shown in Figure 1, an EVPN VPWS network contains the following devices:

· Customer edge (CE)—Customer device directly connected to the service provider network.

· Provider edge (PE)—Service provider device connected to CEs. PEs provide access to the EVPN VPWS network and forward traffic between customer network sites by using public tunnels.

A PE uses ACs, PWs, tunnels, and cross-connects to provide EVPN VPWS services.

· Attachment circuit (AC)—A physical or virtual link between a CE and a PE.

· Pseudowire (PW)—A virtual bidirectional connection between two PEs. A PW comprises a pair of virtual links in opposite directions.

· Public tunnel—A connection that carries one or more PWs across the MPLS or IP backbone. A public tunnel can be an LSP, GRE tunnel, or MPLS TE tunnel.

· Cross-connect—A connection formed by two physical or virtual circuits such as ACs and PWs. It switches packets between the two physical or virtual circuits. Cross-connects include AC to AC cross-connect and AC to PW cross-connect.

Figure 1 EVPN VPWS network

Remote connection establishment

EVPN VPWS remote connection provides point-to-point Layer 2 connectivity between customer network sites by using PWs over an IP or MPLS backbone.

To set up a remote EVPN VPWS connection:

1. Set up a public tunnel to carry one or more PWs between PEs.

2. Set up a PW to connect customer networks.

3. Set up an AC between a PE and a CE.

4. Bind the AC to the PW.

After the PE receives packets from the AC, it adds the PW label into the packets and sends the packets to the peer PE through the public tunnel.

After the peer PE receives the packets from the public tunnel, it removes the PW label of the packets and forwards the packets to the AC bound to the PW.

Public tunnel establishment

The public tunnel can be an LSP, MPLS TE, or GRE tunnel.

If multiple public tunnels are set up between two PEs, you can configure a tunnel policy to control tunnel selection. For more information about tunnel policies, see MPLS Configuration Guide.

If a PW is established over an LSP or MPLS TE tunnel, packets on the PW have two labels. The outer label is the public LSP or MPLS TE tunnel label that MPLS uses to forward the packet to the peer PE. The inner label is the PW label that the peer PE uses to forward the packet to the destination CE.

PW establishment

A PW is established between two PEs based on the local and remote service IDs configured on the PEs. In an EVPN VPWS network, each PE advertises its local service ID through Ethernet auto-discovery routes and compares received local service IDs with its remote service ID. A PE establishes a unidirectional virtual link to a peer If the local service ID advertised by the peer matches the remote service ID. PW establishment is finished when two virtual links in opposite directions are established between two PEs.

AC establishment

For EVPN VPWS, an AC is associated with a cross-connect and can be an Ethernet service instance on a PE. An Ethernet service instance is created on a Layer 2 Ethernet interface to match incoming customer traffic on that interface based on a frame match criterion.

AC-to-PW bindings

For PEs to forward packets between an AC and a PW, bind the AC to the PW.

To configure EVPN VPWS, you must perform the following tasks:

1. Configure an IGP to achieve IP connectivity within the backbone.

2. Configure basic MPLS, LDP, GRE, or MPLS TE to set up public tunnels across the backbone.

Enabling L2VPN

Prerequisites

Before you enable L2VPN, perform the following tasks:

· Configure an LSR ID for the PE by using the mpls lsr-id command.

· Enable MPLS by using the mpls enable command on the transport-facing interface of the PE.

For more information about the mpls lsr-id and mpls enable commands, see MPLS Command Reference.

Configuring an Ethernet service instance on an interface

About this task

When the PE is connected to a CE through a Layer 2 Ethernet interface or Layer 2 aggregate interface, you can configure an Ethernet service instance on the interface to match packets for the AC.

Restrictions and guidelines

You cannot repeat the encapsulation command to modify the frame match criterion of an Ethernet service instance. To change the frame match criterion, first execute the undo encapsulation command to remove the original frame match criterion.

If the frame match criterion of an Ethernet service instance is removed, the binding between the Ethernet service instance and the cross-connect is removed automatically.

Mapping an AC to a cross-connect

About mapping an AC to a cross-connect

After you map an Ethernet service instance to a cross-connect, packets received from the Ethernet service instance are forwarded to the PW or another AC bound to the cross-connect. An Ethernet service instance matches a list of VLANs on a site-facing interface. The PE assigns customer traffic from the VLANs to a cross-connect by mapping the Ethernet service instance to the cross-connect.

When you map an AC to a cross-connect, you can associate Track with the AC. Then, the AC is up only when one or more of the associated track entries are positive.

Restrictions and guidelines for mapping an AC to a cross-connect

This task is mutually exclusive with Ethernet link aggregation. If a Layer 2 Ethernet interface has been added to a link aggregation group, you cannot map an Ethernet service instance on the Layer 2 interface to a cross-connect, and vice versa.

Enabling packet statistics for an AC

Restrictions and guidelines for AC packet statistics

For the statistics enable command to take effect on an Ethernet service instance, you must configure a frame match criterion for the Ethernet service instance and map it to a cross-connect. When you modify the frame match criterion or cross-connect mapping, the packet statistics of the instance are cleared. To display the statistics, use the display l2vpn service-instance verbose command.

To clear packet statistics for ACs, use the reset l2vpn statistics ac command.
