00:00:07,549 --> 00:00:11,809
Welcome to Understanding IP Multicast
Routing, a course designed to help

2
00:00:11,809 --> 00:00:16,129
network engineers build a clear and
practical understanding of how multicast

3
00:00:16,189 --> 00:00:17,789
operates in enterprise networks.

4
00:00:18,488 --> 00:00:22,238
Whether you're preparing for the
CCNP Enterprise or CCIE Enterprise

5
00:00:22,238 --> 00:00:25,338
Infrastructure certifications, or
simply looking to strengthen your

6
00:00:25,338 --> 00:00:29,538
routing expertise, this course walks
you through multicast step by step.

7
00:00:30,542 --> 00:00:34,702
This course is taught by Keith Bogart,
a networking veteran with over 25 years

8
00:00:34,702 --> 00:00:38,522
of experience, including roles as a
Cisco TACK engineer and instructor.

9
00:00:39,131 --> 00:00:43,251
Keith holds a CCIE certification and has
taught a wide range of internetworking

10
00:00:43,251 --> 00:00:44,511
topics throughout his career.

11
00:00:45,479 --> 00:00:48,029
We begin with the fundamentals
of multicast communication.

12
00:00:48,668 --> 00:00:52,958
You’ll explore how multicast differs
from unicast and broadcast, how multicast

13
00:00:52,958 --> 00:00:57,708
addressing works at both Layer 2 and
Layer 3, and how hosts signal multicast

14
00:00:57,708 --> 00:01:00,828
group membership using IGMP and MLDP.

15
00:01:01,418 --> 00:01:04,448
From there, the course introduces
the core routing technology that

16
00:01:04,448 --> 00:01:09,448
enables scalable multicast delivery:
Protocol Independent Multicast, or pim.

17
00:01:10,528 --> 00:01:14,798
The course provides a detailed walkthrough
of pim Sparse Mode, including how shared

18
00:01:14,848 --> 00:01:18,898
trees are created, how sources register
with the Rendezvous Point, and how

19
00:01:18,898 --> 00:01:22,358
receivers transition to shortest-path
trees for optimal forwarding.

20
00:01:22,898 --> 00:01:26,008
You’ll also learn how Designated
Rout-ers manage multicast traffic,

21
00:01:26,448 --> 00:01:30,108
and how networks dynamically discover
Rendezvous Points using Cisco

22
00:01:30,108 --> 00:01:33,608
Auto-RP and the standards-based
pim Bootstrap Router mechanism.

23
00:01:34,601 --> 00:01:37,321
By the end of this course, you’ll
be able to explain how multicast

24
00:01:37,321 --> 00:01:41,181
traffic is distributed across routed
networks, understand the mechanics

25
00:01:41,181 --> 00:01:45,261
of pim Sparse Mode, configure and
verify multicast routing features,

26
00:01:45,631 --> 00:01:48,971
and troubleshoot multicast behavior
using industry-standard tools.

27
00:01:49,966 --> 00:01:53,646
To get the most from this course, learners
should have a basic understanding of IP

28
00:01:53,646 --> 00:01:57,996
routing and enterprise networking, along
with CCNA-level networking knowledge.

29
00:01:59,246 --> 00:02:02,296
Multicast plays an important role
in applications such as video

30
00:02:02,296 --> 00:02:06,626
distribution, financial market data
feeds, and large-scale content delivery.

31
00:02:07,281 --> 00:02:11,511
In Understanding IP Multicast rout-ing,
you’ll develop the knowledge and

32
00:02:11,511 --> 00:02:15,391
practical insight needed to confidently
design, configure, and troubleshoot

33
00:02:15,454 --> 00:02:17,464
multicast in modern enterprise networks.
