Junos Multicast Routing (JMR)


LENGTH: 16 Hours (2 days)

PRICE: £1,700.00


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.

The Junos Multicast Routing (JMR) course is an advanced-level course.
