00:00.000 --> 00:02.720
All right, let's go ahead and go through this challenge together.

2
00:02.720 --> 00:06.280
Remember how all of these pieces fit together in the architecture.

3
00:06.280 --> 00:07.280
Let's go and order here.

4
00:07.280 --> 00:12.720
So routing protocols, they are going to maintain their own databases and tables

5
00:12.720 --> 00:12.960
, and they're

6
00:12.960 --> 00:17.050
going to feed that information into the routing information base or the RIB,

7
00:17.050 --> 00:18.320
which is essentially

8
00:18.320 --> 00:20.280
the global routing table.

9
00:20.280 --> 00:24.150
Now MAC addresses are also being learned by a layer two and even a layer three

10
00:24.150 --> 00:24.760
device,

11
00:24.760 --> 00:29.480
and those are going to go into the cam table that is going to be used because

12
00:29.480 --> 00:30.520
we're talking
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

12
00:29.480 --> 00:30.520
we're talking

13
00:30.520 --> 00:35.480
about a very fast lookups of exact matches.

14
00:35.480 --> 00:38.880
Now in exact matches, these are going to require a new memory type, which is

15
00:38.880 --> 00:40.800
that ternary cam.

16
00:40.800 --> 00:43.760
This is going to allow me to use masks.

17
00:43.760 --> 00:46.990
And so that's going to allow me to store access control lists and quality of

18
00:46.990 --> 00:48.640
service configuration

19
00:48.640 --> 00:53.280
as well as routing information here in the form of Sef.

20
00:53.280 --> 00:57.600
Now Sef consists of a couple of different components here.

21
00:57.600 --> 01:02.390
It's going to consist of our fib, the forwarding information base, which is
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

21
00:57.600 --> 01:02.390
It's going to consist of our fib, the forwarding information base, which is

22
01:02.390 --> 01:03.400
copied directly

23
01:03.400 --> 01:04.560
out of the RIB.

24
01:04.560 --> 01:08.560
And then we're going to take some important layer two information and put that

25
01:08.560 --> 01:09.080
into the

26
01:09.080 --> 01:12.040
adjacency table.

27
01:12.040 --> 01:17.280
So Sef consists of these two components right here.

28
01:17.280 --> 01:19.960
So it's all a matter of how it all fits together.

29
01:19.960 --> 01:24.020
I guess we could think of it as a puzzle, just making sure that we can, that we

30
01:24.020 --> 01:24.400
understand

31
01:24.400 --> 01:27.750
the purpose of each one of these components as it relates to switching, whether

32
01:27.750 --> 01:28.200
it's layer

33
01:28.200 --> 01:33.160
two switching or importantly even with layer three switching and how that ties

X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

33
01:28.200 --> 01:33.160
two switching or importantly even with layer three switching and how that ties

34
01:33.160 --> 01:34.280
into routing.

35
01:34.280 --> 01:36.880
I hope there's been a formative for you and I'd like to thank you for viewing.
