In the previous video, we already learn about inter vlan routing, which is connecting between 2
pc in the different vlan using router. 3
And we also already learn about dhcp server, so all computer can get an ip address automatically. 4
Now, in this video, we are going to learn about switch virtual interface. 5
What is that? 6
Switch virtual interface or svi is a method to connecting between pc in the different 7
vlan without router, but we can using multi layer switch, or MLS 8
or some people also call layer 3 switch. 9
Here we can see that we have two type of switch, the first one is 2960, 10
and the second one is 3560. 11
Here the first number indicate the type of switch. 12
If the first number is 2 like this, so this is layer 2 switch, but if the first number 13
is 3 like this, so this is layer 3 switch. 14
In the previous video, we already learn that if we want to connecting between pc in the 15
different vlan, we need a router. 16
But now, we are going to learn something new, which is connecting between pc in the different 17
vlan using multi layer switch. 18
If the switch is multi layer switch or layer 3 switch, so we can connecting different network 19
using switch. 20
Because the switch have an ability for layer 3. 21
Remember that layer 3 is connection between different network. 22
This is why we call this switch as multi layer switch. 23
In cisco switch, if the series number started by 3, so this is layer 3 switch or multi layer switch. 24
And if the series number started by 2, this means that the switch is only layer 2, 25
which is only use to connecting between pc in the same network. 26
If we want to connecting between pc in the different vlan, we can not use layer 2 switch. 27
We must use multi layer switch, which is switch series that started by 3. 28
Okay I think enough for this video, in the next video, we are going to learn how to connecting 29
between pc in the different vlan using multi layer switch. 30
Thankyou for watching and see you on the next video.
