Overview

This three-day course is designed to provide students with MPLS-based Layer 3 virtual private network (VPN) knowledge and configuration examples. The course includes an overview of MPLS Layer 3 VPN concepts, scaling Layer 3 VPNs, Internet access, Interprovider Layer 3 VPNs, and Multicast for Layer 3 VPNs. This course also covers Junos operating system-specific implementations of Layer 3 VPNs. The concepts are put into practice with a series of in-depth hands-on labs, which will allow participants to gain experience in configuring and monitoring Layer 3 VPNs on Junos OS devices. These hands-on labs utilize Juniper Networks vMX Series devices using the Junos OS Release 16.1R3.10, but are also applicable to other MX Series devices.

Through demonstrations and hands-on labs, students will gain experience in configuring and monitoring the Junos OS and in device operations. JL3V is an advanced-level course.

Objectives

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

  • Describe the value of MPLS VPNs.
  • Describe the differences between provider-provisioned VPNs and customer-provisioned VPNs.
  • Describe the differences between Layer 2 VPNs and Layer 3 VPNs.
  • List the provider-provisioned MPLS VPN features supported by the Junos OS software.
  • Describe the roles of a CE device, PE router, and P router in a BGP Layer 3 VPN.
  • Describe the format of the BGP routing information, including VPN-IPv4 addresses and route distinguishers.
  • Describe the propagation of VPN routing information within an AS.
  • List the BGP design constraints to enable Layer 3 VPNs within a provider network.
  • Explain the operation of the Layer 3 VPN data plane within a provider network.
  • Create a routing instance, assign interfaces to a routing instance, create routes in a routing instance, and import/export routes from a routing instance using route distinguishers/route targets.
  • Describe the purpose of BGP extended communities, configure extended BGP extended communities, and use BGP extended communities.
  • List the steps necessary for proper operation of a PE-CE dynamic routing protocol.
  • List the troubleshooting and monitoring techniques for routing instances.
  • Explain the difference between the bgp.l3vpn table and the inet.0 table of a routing instance.

  • Describe the RFC 4364 VPN options.
  • Describe the carrier-of-carriers model.
  • Configure the carrier-of-carriers and "Option C" configuration.
  • Describe the flow of control and data traffic in a draft-rosen multicast VPN.
  • Describe the configuration steps for establishing a draft-rosen multicast VPN.
  • Monitor and verify the operation of draft-rosen multicast VPNs.
  • Describe the flow of control traffic and data traffic in a next-generation multicast VPN.
  • Describe the configuration steps for establishing a next-generation multicast VPN.
  • Describe the configuration steps for establishing a next-generation multicast VPN.
  • Monitor and verify the operation of next-generation multicast VPNs.
  • Describe the flow of control traffic and data traffic when using MPVNs for Internet multicast.
