Price: $1,900.00

2 Days

Skip to Schedule

This two-day course is designed to provide students 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), Bidirectional PIM, and Multicast Source Discovery Protocol (MSDP).

Through demonstrations and hands-on labs, students will gain experience in configuring and monitoring Junos OS and device and protocol operations. The course uses the Juniper Networks vMX Series devices for the hands-on component, though the course may be applicable to other Juniper hardware platforms running Junos OS. This course is based on Junos OS release 21.4R1.12.

  • Describe multicast routing protocols.
  • Describe PIM.
  • Configure PIM.
  • Describe and configure MSDP.
  • Describe and configure source-specific multicast.
  • Describe and configure multicast policy.
  • Describe the IPv6 multicast fundamental concepts

  • Identify the role of a policy in controlling MSDP message advertisement
  • Explain how you can use a policy to scope multicast groups
  • Lab 5: Multicast and Policy

A Appendix: IPv6 Multicast

  • Describe load balancing and auto scaling
Students should have basic networking knowledge and an understanding of the Open Systems Interconnection (OSI) model and the TCP/IP protocol suite. Students should also have working knowledge of security policies. Students should also attend the Introduction to the Junos Operating System (IJOS), Junos Routing Essentials (JRE), and Junos Intermediate Routing (JIR) courses prior to attending this class.
