Example: Configuring VPWS with EVPN Signaling Mechanisms
date_range
20-Dec-24
This example shows how to implement Virtual Private Wire Service (VPWS) with Ethernet Virtual Private Network (EVPN) signaling. The use of EVPN signaling provides single-active or all-active multihoming capabilities for BGP-signaled VPNs.
Requirements
This example uses the following hardware and software components:
Four MX Series routers acting as provider edge (PE) devices, running Junos OS Release 17.1 or later
Two customer edge (CE) devices (MX Series routers are used in this example)
Overview and Topology
VPWS employs Layer 2 VPN services over MPLS to build a topology of point-to-point connections that connect end customer sites. EVPN enables you to connect dispersed customer sites using a Layer 2 virtual bridge. Starting with Junos OS Release 17.1, these two elements can be combined to provide an EVPN-signaled VPWS.
The vpws-service-id statement identifies the endpoints
of the EVPN-VPWS based on local and remote service
identifiers configured on the PE routers in the network. These endpoints
are autodiscovered using BGP-based EVPN signaling to exchange the
service identifier labels.
Topology
This example uses the topology shown in Figure 1, consisting of four PE routers and two CE routers. Router CE1 is multihomed to Routers PE1 and PE2; Router CE2 is multhomed to Routers PE3 and PE4.
Figure 1: VPWS with EVPN Signaling
The following configuration elements are used in this scenario:
CE devices:
Aggregated Ethernet (AE) interface towards related PE devices
PE devices:
AE interface, with EVPN segment identifier (ESI), towards related CE device
OSPF and IBGP in the core
MPLS LSPs using RSVP in the core
Per-packet load balancing
Routing instance using instance type
evpn-vpws, and thevpws-service-idstatement to define the local and remote endpoints.
Configuration
CLI Quick Configuration
To quickly configure this example, copy the
following commands, paste them into a text file, remove any line breaks,

Procedure
Step-by-Step Procedure
The following example requires that you navigate various levels in the configuration hierarchy. For information about navigating the CLI, see Using the CLI Editor in Configuration Mode in the CLI User Guide.
Note:
Only Router PE1 is shown here. Repeat this procedure for all other PE devices, using the appropriate interface names, addresses, and other parameters for each device.
The step-by-step procedure for CE devices is not shown.
To configure Router PE1:
Configure the CE-facing interface to be part of the ae0 bundle.
The second interface for the AE bundle will be configured on the other local PE device.

Configure a routing instance using the
evpn-vpwsinstance type. Add the AE (CE-facing) interface configured earlier, as well as a route distinguisher and VRF target.In EVPN terms, this is an EVPN instance (EVI).

active LACP connections between the CE device and its local PE devices.
Note also that the system ID configured on the PE devices, 00:00:00:00:00:01 (and shown on the PE device outputs as the Actor), matches
the Partner system ID value on the CE device.

Meaning
The outputs show the ESI routes being shared across the VPWS to the remote PE devices.
The routes beginning with 1:198.51.100.x:0:: are
the per-Ethernet-segment autodiscovery Type 1 EVPN routes originating
from the remote PE devices. The route distinguishers (RDs) are derived
at the global level of the devices.
The routes beginning with 1:198.51.100.x:11:: are
the per-EVI autodiscovery Type 1 EVPN routes from the remote PE devices.
The RDs are taken from the remote PE devices’ routing instances.

Meaning
In addition to the remote ESI routes being shared across the VPWS, as explained in the previous section, the EVPN table on each PE device also includes a local ESI route. This Type 1 route represents the locally configured Ethernet segment, and is derived from the locally configured RD and ESI values.
