Example: Configuring VXLAN Data Center Interconnect Using EVPN
This example shows how to configure Virtual Extensible Local Area Network (VXLAN) data center connectivity using Ethernet VPN (EVPN) to leverage the benefits of EVPN as a data center interconnect (DCI) solution.
Requirements
This example uses the following hardware and software components:
Two provider edge (PE) devices in different data centers (DCs) acting as VXLAN tunnel endpoints (VTEPs).
Two customer edge (CE) devices.
Four host devices connected to each PE and CE device.
Before you begin:
Configure the device interfaces.
Configure an IGP, such as OSPF, on all the devices.
Establish a BGP session between the PE devices.
Configure MPLS and RSVP on the PE devices.
Configure PIM on the CE devices and in the routing instance of the PE devices.
Overview
VXLAN is a technology that provides intra data center connectivity using a tunneling scheme to stretch Layer 2 connections over an intervening Layer 3 network.
The Ethernet VPN (EVPN) technology, on the other hand, provides a solution for multipoint Layer 2 VPN services with advanced multihoming capabilities, using BGP control plane over MPLS/IP network.
Although several solutions are available for data center connectivity, the integration of EVPN with VXLAN in Junos OS Release 16.1 and later releases, provides an added advantage over the existing MPLS data center interconnect (DCI) technologies.
EVPN provides mechanisms for next generation DCI by adding extended control plane procedures to exchange Layer 2 MAC address and Layer 3 IP address information among the participating Data Center Border Routers (DCBRs). EVPN with its advanced features like active-active redundancy, aliasing, and mass MAC withdrawal helps in addressing the DCI challenges, such as seamless VM mobility and optimal IP routing, thus making it essential to provide VXLAN solutions over EVPN.
Figure 1 illustrates VXLAN data center interconnect using EVPN between devices PE1 and PE2 that are located in different data centers (DC1 and DC2, respectively). Each PE device is connected to one CE device and one host. All the PE and CE devices are configured under VLAN 10, and with the same VXLAN Network Identifier (VNI) of 10. Devices CE1 and PE1 belong to the multicast group of 192.168.1.10, and devices CE2 and PE2 belong to the multicast group of 172.16.1.10.
