Junos Multicast Routing (JMR)


Course Content

This two-day course is designed to provide you with detailed coverage of multicast protocols including Internet Group Management Protocol (IGMP), Protocol Independent Multicast–Dense Mode (PIM-DM), Protocol Independent Multicast–Sparse Mode (PIM-SM) and Multicast Source Discovery Protocol (MSDP).

Through demonstrations and hands-on labs, you will gain experience in configuring and monitoring the Junos operating system and monitoring device and protocol operations.

Certification: JNCIP-SP - JN0-661

Who should attend

This course benefits individuals responsible for implementing, monitoring, and troubleshooting multicast components in a service provider’s network.



Course Objectives

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

  • Describe IP multicast traffic flow .
  • Identify the components of IP multicast.
  • Explain how IP multicast addressing works.
  • Describe the need for reverse path forwarding (RPF) in multicast.
  • Explain the role of IGMP and describe the available IGMP versions.
  • Configure and monitor IGMP.
  • Identify common multicast routing protocols.
  • Explain the differences between dense-mode and sparse-mode protocols.
  • Describe rendezvous point (RP) discovery options.
  • Describe bidirectional PIM.
  • Configure and monitor rendezvous point discovery mechanisms.
  • Configure bidirectional PIM sparse mode.
  • Explain the purpose and operation of MSDP.
  • Describe the usage of MSDP within a single PIM domain with anycast-RP.
  • Describe the usage of MSDP across multiple PIM domains.
  • Configure and monitor MSDP.
  • Compare the any-source multicast (ASM) and source-specific multicast (SSM) service models.
  • Describe the basic requirements, benefits, and caveats of SSM.
  • List the address ranges used for SSM.
  • Illustrate the role of IGMPv3 and PIM-SM in an SSM implementation.
  • Configure and monitor SSM.
  • Describe the default PIM sparse mode information distribution.
  • Explain how routing policies control IGMP joins.
  • Explain how routing policies alter PIM protocol message flow.
  • Identify the role of a policy in controlling MSDP message advertisement.
  • Explain how you can use a policy to scope multicast groups.
  • Configure and monitor PIM dense mode and PIM sparse mode.
  • Describe IPv6 multicast addresses.
  • Describe IPv6 multicast scoping.
  • Compare IPv6 Multicast Listener Discovery (MLD) versions with IPv4’s IGMP protocol versions.
  • Describe IPv6 SSM.
