Welcome to Understanding IP Multicast Routing, a course designed to help
network engineers build a clear and practical understanding of how multicast
operates in enterprise networks.
Whether you're preparing for the CCNP Enterprise or CCIE Enterprise
Infrastructure certifications, or simply looking to strengthen your
routing expertise, this course walks you through multicast step by step.
This course is taught by Keith Bogart, a networking veteran with over 25 years
of experience, including roles as a Cisco TACK engineer and instructor.
Keith holds a CCIE certification and has taught a wide range of internetworking
topics throughout his career.
We begin with the fundamentals of multicast communication.
Youâll explore how multicast differs from unicast and broadcast, how multicast
addressing works at both Layer 2 and Layer 3, and how hosts signal multicast
group membership using IGMP and MLDP.
From there, the course introduces the core routing technology that
enables scalable multicast delivery: Protocol Independent Multicast, or pim.
The course provides a detailed walkthrough of pim Sparse Mode, including how shared
trees are created, how sources register with the Rendezvous Point, and how
receivers transition to shortest-path trees for optimal forwarding.
Youâll also learn how Designated Rout-ers manage multicast traffic,
and how networks dynamically discover Rendezvous Points using Cisco
Auto-RP and the standards-based pim Bootstrap Router mechanism.
By the end of this course, youâll be able to explain how multicast
traffic is distributed across routed networks, understand the mechanics
of pim Sparse Mode, configure and verify multicast routing features,
and troubleshoot multicast behavior using industry-standard tools.
To get the most from this course, learners should have a basic understanding of IP
routing and enterprise networking, along with CCNA-level networking knowledge.
Multicast plays an important role in applications such as video
distribution, financial market data feeds, and large-scale content delivery.
In Understanding IP Multicast rout-ing, youâll develop the knowledge and
practical insight needed to confidently design, configure, and troubleshoot
multicast in modern enterprise networks.
