Next Generation Multicast VPN (NG-MVPN) configuration example

Next Generation Multicast VPN (NG-mVPN)

NG-mVPN is a next-generation multicast distribution technology that is predominantly used in service provider networks and addresses scalability and manageability issues associated with the previous generation of SP Multicast VPN (Draft Rosen).

In this article, we will go through configuration steps you’d need to undertake to configure NG-mVPN in a Juniper environment. We will also discuss BGP advertisements that are associated with multicast sources and receivers connected to the network.

EVPN MPLS Port-Based VLAN-Aware Bundle Service

In this article, we will review EVPN MPLS Port-Based VLAN-Aware Bundle Service  configuration example using Juniper MX devices. As per Port-Based VLAN-Aware service definition in RFC7432, all of the VLANs on the port are part of the same service and are mapped to a single bundle without any VID translation.

In our sample, we will add L3 IRB interfaces to VLANs, simulating L3 Default Gateways.

Inter-subnet routing in EVPN MPLS Environment

In this article, we will review inter-subnet routing scenarios in EVPN environment. As we will discover, certain topologies might lead to sub-optimal traffic flows within EVPN network.

Our setup will be comprised of three PE and four CE devices as shown below:

EVPN Type 5 Configuration Example – Juniper MX

Introduction

In this example, we will show how to configure L2 and L3 EVPN service on Juniper MX devices.

If you are not familiar with EVPN, please review our introductory articles on EVPN.

In this lab, we will leverage our previous example, where we delivered L2 connectivity between multiple sites, and will augment it with L3 site-to-site connectivity options.

One shared broadcast domain with IP range 1.1.1.0/24 is used on PE-CE interfaces across the entire network. Each CE site is assigned a unique subnet on LAN interface.
