00:00:08,450 --> 00:00:12,395
Hello, and welcome to
discovering the RP.

4
00:00:12,395 --> 00:00:15,980
In this skill, we're going
to look at different ways

5
00:00:15,980 --> 00:00:20,240
that our PIM routers can
discover where the RP is,

6
00:00:20,240 --> 00:00:24,860
which, of course, is necessary
when operating in sparse mode.

7
00:00:24,860 --> 00:00:27,740
As we mentioned during
our discover multicast

8
00:00:27,740 --> 00:00:30,740
routing skill, there
are several ways

9
00:00:30,740 --> 00:00:33,290
that we can discover
where the RP is.

10
00:00:33,290 --> 00:00:36,560
So we're going to discuss
those in this skill in much

11
00:00:36,560 --> 00:00:37,830
more detail.

12
00:00:37,830 --> 00:00:43,010
So first, we'll start by talking
about a static configuration.

13
00:00:43,010 --> 00:00:45,630
This is actually
fairly straightforward.

14
00:00:45,630 --> 00:00:48,980
We're just going to be
manually configuring the RP's

15
00:00:48,980 --> 00:00:51,630
address on each of the devices.

16
00:00:51,630 --> 00:00:55,070
So we'll take a look at the
pros and cons of that choice.

17
00:00:55,070 --> 00:00:59,420
Second, we'll take a look at
a Cisco proprietary feature

18
00:00:59,420 --> 00:01:01,730
called Auto-RP.

19
00:01:01,730 --> 00:01:06,180
This is a way to dynamically
find the RP in our environment,

20
00:01:06,180 --> 00:01:09,360
and it allows for a
bit of redundancy.

21
00:01:09,360 --> 00:01:14,040
Then we'll move on
to BSR, or Bootstrap

22
00:01:14,040 --> 00:01:16,920
Router, which is an
industry standard

23
00:01:16,920 --> 00:01:19,710
equivalent for Auto-RP.

24
00:01:19,710 --> 00:01:22,530
Now, of course, they function
a little bit differently

25
00:01:22,530 --> 00:01:24,250
and we will discuss that.

26
00:01:24,250 --> 00:01:27,960
However, they perform
the same basic job.

27
00:01:27,960 --> 00:01:30,780
And then we'll wrap up
with not really a way

28
00:01:30,780 --> 00:01:33,240
of discovering the
RP, so to speak,

29
00:01:33,240 --> 00:01:38,940
but sort of a way of running
the RP, which is anycast RP.

30
00:01:38,940 --> 00:01:41,850
This allows for some
different types of redundancy

31
00:01:41,850 --> 00:01:46,140
and load-sharing, and this
can be combined with any

32
00:01:46,140 --> 00:01:47,950
of these other choices.

33
00:01:47,950 --> 00:01:52,920
So we can still discover with
either static, Auto-RP, or BSR

34
00:01:52,920 --> 00:01:57,390
but still run our
RP using anycast.

35
00:01:57,390 --> 00:02:00,480
So as you can see, there's
a lot of fun stuff in here

36
00:02:00,480 --> 00:02:01,840
we have to talk about.

37
00:02:01,840 --> 00:02:03,820
Let's go ahead and jump in.

38
00:02:03,820 --> 00:02:07,220
I'll see you in the next video.
