JL3V Junos Layer 3 VPNs (JL3V)

  • Duration: 3 days
  • Price: $
  • Certifications: JNCIP SP

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. These 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 19.4R1.10, and are also applicable to other MX Series devices

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 VPNIPv4 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.
• Monitor the operation of a CE-PE dynamic routing protocol.
• Explain the operation of a PE multi-access interface in a Layer 3 VPN and
list commands to modify that behavior.
• Describe ways to support communication between sites attached to a
common PE router.
• Provision and troubleshoot hub-and-spoke Layer 3 VPNs,
• Describe the flow of control traffic and data traffic in a hub-and-spoke Layer 3 VPN.
• Describe QoS mechanisms available in L3VPNs.
• Configure L3VPN over GRE tunnels.
• 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 multicastVPN.
• Describe the configuration steps for establishing a draft-rosen multicastVPN.
• 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.
• 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.
• Describe the configuration steps for enabling internet multicast using MVPNs.
• Monitor and verify the operation of MVPN internet multicast.

Intermediate-level networking knowledge and an understanding of OSPF, ISIS, BGP, and Junos policy
• Experience configuring MPLS label-switched paths using Junos
• Attend the Introduction to the Junos Operating System (IJOS), Junos Intermediate Routing (JIR), and Junos MPLS Fundamentals (JMF) courses prior to attending this class
