1

00:00:00,533  -->  00:00:06,303
In the previous video, we already configure
etherchannel LACP and PAGP.

2

00:00:06,857  -->  00:00:14,903
That 2 protocol is layer 2 etherchannel, this
is means that we configure trunk in the etherchannel.

3

00:00:15,645  -->  00:00:20,798
Remember that before we configure etherchannel,
we configure trunk first.

4

00:00:22,061  -->  00:00:27,346
Now, in this video we are going to learn
about layer 3 etherchannel.

5

00:00:28,099  -->  00:00:35,145
In layer 3 etherchannel, the interface will
not configured as trunk, but we will configure

6

00:00:35,145  -->  00:00:38,122
an ip address in the etherchannel.

7

00:00:39,307  -->  00:00:45,814
And one thing that you need to know is layer
3 etherchannel only work on layer 3 switch.

8

00:00:46,334  -->  00:00:51,471
So we can not configure layer 3 etherchannel
in switch 2960,

9

00:00:52,855  -->  00:01:00,482
Okay let’s just start, let’s create a
new topology, import two 3560 switch.

10

00:01:03,561  -->  00:01:06,000
And then connecting this 2 switch.

11

00:01:14,557  -->  00:01:20,585
Because this will become layer 3 etherchannel,
so we will configure an ip address.

12

00:01:21,172  -->  00:01:27,727
Let’s say in multi layer switch 1, the ip
address is 10.10.10.1,

13

00:01:28,569  -->  00:01:34,138
and in multi layer switch 2, the ip address is 10.10.10.2.

14

00:01:34,968  -->  00:01:46,145
Let’s start the configuration, enable, here
we can see that the interface is fa0/1-3,

15

00:01:48,625  -->  00:01:56,732
so interface range fa0/1-3, if we want to
configure an ip address in the multi layer

16

00:01:56,732  -->  00:02:03,413
switch, we need to disable the switchport,
the command is no switchport.

17

00:02:04,676  -->  00:02:14,494
Next let’s configure the etherchannel, channel-group
1 mode and then question mark,

18

00:02:15,158  -->  00:02:19,153
to configure layer 3 etherchannel, we can use mode on.

19

00:02:22,287  -->  00:02:29,373
Here we can see creating port channel 1, this
is because we use id 1 for the etherchannel.

20

00:02:30,126  -->  00:02:32,740
Next let’s configure the ip address.

21

00:02:33,238  -->  00:02:44,586
We will configure the ip address on the etherchannel
interface, so interface po1, ip address 10.10.10.1

22

00:02:44,586  -->  00:02:48,000
255.255.255.0,

23

00:02:49,157  -->  00:02:55,604
Okay now we have done in multi layer switch 1,
let’s move to multi layer switch 2.

24

00:03:00,100  -->  00:03:09,573
No, enable, configure terminal, interface
range fa0/1-3.

25

00:03:10,459  -->  00:03:14,877
First let’s disable the switchport, no switchport,

26

00:03:15,951  -->  00:03:21,585
Next let’s configure the etherchannel, channel-group
1 mode on.

27

00:03:24,530  -->  00:03:36,456
Next let’s configure the ip address, interface
po1, ip address 10.10.10.2 255.255.255.0,

28

00:03:37,641  -->  00:03:47,580
Okay now we have done configuring layer 3
etherchannel, let’s check it, do show etherchannel summary,

29

00:03:50,204  -->  00:03:58,402
here we have port channel 1, Uppercase
R and uppercase U, uppercase R means Layer 3

30

00:03:58,690  -->  00:04:01,363
and uppercase U means in use,

31

00:04:01,995  -->  00:04:07,872
The protocol is none, and all of interface
is in port channel.

32

00:04:08,724  -->  00:04:14,448
Let’s also check on multi layer switch 2,
do show etherchannel summary.

33

00:04:15,733  -->  00:04:22,039
Here also uppercase R and uppercase U, this
is means layer 3 and in use.

34

00:04:23,058  -->  00:04:33,000
Now let’s test ping, from multi layer switch
2 ping to multi layer switch 1, do ping 10.10.10.1,

35

00:04:34,902  -->  00:04:38,307
okay here we can see that the result is success.

36

00:04:39,470  -->  00:04:41,428
I think enough for this video

37

00:04:41,428  -->  00:04:44,768
Thankyou for watching and see you on the next video.
