Junos Layer 2 VPNs

LEVEL 33 DAY COURSE
LEVEL 3

COURSE DESCRIPTION

This three-day course is designed to provide students with the knowledge to configure and troubleshoot MPLS-based Layer 2 virtual private networks (VPN). The course includes an overview of MPLS Layer 2 VPN concepts, such as BGP Layer 2 VPNs, LDP Layer 2 circuits, forwarding equivalence class (FEC) 129, virtual private LAN service (VPLS), Ethernet VPN (EVPN), and Inter-AS MPLS VPNs. This course also covers Junos OS-specific implementations of Layer 2 VPN instances, VPLS, and EVPNs. This course is based on the Junos OS Release 21.4R1.12.

Objectives

After successfully completing this course, you should be able to:

  • Describe some of the different kinds of VPNs, their mechanics, and their use cases.
  • Describe the types of MPLS VPN that operate at layer 2.
  • Describe the mechanics of BGP-signaled pseudowires, also known as L2VPNs.
  • Configure BGP-signaled L2VPNs with Ethernet and Ethernet-VLAN encapsulations.
  • Demonstrate how to troubleshoot some of the most common BGP-signaled L2VPN configuration problems.
  • Describe how BGP-signaled L2VPNs use a block of labels to bring efficiency to huband-spoke advertisements.
  • Configure advanced BGP-signaled L2VPN features, such as multihoming, VLAN normalization, and route target constraint.
  • Describe the mechanics of LDP-signaled pseudowires, also known as Layer 2 Circuits.
  • Describe the causes and solutions of some of the most common L2 Circuit configuration problems.
  • Configure advanced LDP-signaled L2Circuit features, such as multihoming and local switching.
  • Explain how the FEC 129 pseudowire method combines BGP for autodiscovery and LDP for signaling.
  • Describe the purpose and mechanics of a VPLS.
  • Create a VPLS instance that is signaled using BGP and demonstrate the commands that verify its status.
  • Create VPLS instances that are signaled using LDP and FEC 129 and demonstrate the commands available to verify their status.
  • Describe how mismatched VLAN tags are handled in a default VPLS configuration.
  • Configure a VPLS to swap mismatched VLAN tags automatically, and to create multiple bridge domains inside a single VPLS instance.
  • Configure the most important VPLS traffic management features, including flood protection, MAC limiting, IRB interfaces, and automated Site IDs.
  • Configure hub-and-spoke VPLS topologies.
  • Configure multihomed sites in a VPLS.
  • Describe the features of Ethernet VPN, and the enhancements that EVPN brings over VPLS.
  • Explain how EVPNs advertise MAC addresses, and how they request to receive flooded traffic within a bridge domain.
  • Configure and verify a single-homed VLAN-based EVPN instance.
  • Configure and verify a single-homed VLAN-aware bundle EVI.
  • Configure a multihomed EVPN and explain the purpose of the EVPN Type 4 route.
  • Describe the features provided by EVPN Type 1 routes.
  • Describe how to use MAC Mobility and IRB interfaces in an EVPN.
  • Explain how EVPNs can tightly integrate themselves into MPLS Layer 3 VPNs to provide highly efficient forwarding.
  • Describe and configure various solutions that create MPLS VPNs between service providers.
  • Describe the circuit-cross connect pseudowire method and explain how this old method can still have value in modern networks.
  • Describe how multisegment pseudowires can create layer 2 VPNs across autonomous system boundaries
