1
00:00:00,640 --> 00:00:04,570
The VPN config generator makes us very easy to set up.

2
00:00:05,200 --> 00:00:07,510
In this example, I've got router one and router two.

3
00:00:07,510 --> 00:00:13,510
Router one has this IP address quadruple one, router two has this IP address quadruple two on these

4
00:00:13,510 --> 00:00:14,470
interfaces.

5
00:00:14,560 --> 00:00:18,790
Router one is going to be configured with this tunnel number and router two is going to be configured

6
00:00:18,790 --> 00:00:19,960
with this tunnel number.

7
00:00:21,740 --> 00:00:24,290
But it's very easy to change that kind of information.

8
00:00:24,560 --> 00:00:30,800
I could change the router name and notice little change in the diagram and update the configuration

9
00:00:30,800 --> 00:00:31,610
accordingly.

10
00:00:33,540 --> 00:00:41,400
I could, as an example, decide to use tunnel 100 on both sides rather than using different numbers

11
00:00:41,400 --> 00:00:43,050
for the tunnels.

12
00:00:43,690 --> 00:00:48,400
I could also change the subnet used across the jury tunnel.

13
00:00:52,110 --> 00:00:56,730
Just make sure that the IP addresses are in the same subnet because this is like a point to point link.

14
00:00:58,120 --> 00:01:01,000
So the IP addresses need to be in the same subnet.

15
00:01:01,180 --> 00:01:05,170
Click show result and you'll be able to see the details here.

16
00:01:05,590 --> 00:01:13,210
So as an example, on router one, we can see a description with a link to router to the IP address,

17
00:01:13,510 --> 00:01:16,900
tunnel source and tunnel destination for this tunnel.

18
00:01:17,660 --> 00:01:22,760
You can either use physical interfaces or source IP addresses as the source of the tunnel.

19
00:01:22,880 --> 00:01:28,520
In this example, we're using physical interfaces he has alluded to once again, write a one.

20
00:01:30,050 --> 00:01:38,750
You be able to see the description as well as adjustments for maximum transmission unit and negotiation

21
00:01:38,780 --> 00:01:41,090
of maximum transmission unit.

22
00:01:41,480 --> 00:01:48,260
Now adjust RMS is a big discussion, but essentially it allows devices to negotiate the size of MTU

23
00:01:48,260 --> 00:01:55,070
use so they don't try and send packets that are too big that can't be transmitted across this link.

24
00:01:55,280 --> 00:01:59,180
We have to reduce once again the size of the payload.

25
00:02:00,570 --> 00:02:07,830
Because of the additional headers added by G e, you could adjust that to a lower number if necessary.

26
00:02:08,430 --> 00:02:12,540
So in both sides, just set the M2 value accordingly.

27
00:02:12,570 --> 00:02:13,950
Click on show result.

28
00:02:15,060 --> 00:02:19,560
And that will then adjust these two commands based on your inputs.

29
00:02:20,840 --> 00:02:23,960
A more complex configurator is also available.

30
00:02:24,560 --> 00:02:29,810
So we have an IPsec Configurator and when I click on Show Result here.

31
00:02:31,210 --> 00:02:38,380
You'll notice that there is more involved because you have to set up both the encryption and authentication

32
00:02:38,380 --> 00:02:39,610
on this, rather.

33
00:02:40,360 --> 00:02:42,400
You have to determine which traffic is interesting.

34
00:02:42,400 --> 00:02:51,580
You have to set your ISO and PE policies as well as your IP policies so there's more configuration involved.

35
00:02:51,580 --> 00:02:58,960
But the VPN config generator makes it very easy to select which options you're going to be using for

36
00:02:58,960 --> 00:03:01,120
encryption and authentication.

37
00:03:02,700 --> 00:03:07,860
And then you simply click on show result and the configuration will be changed accordingly.
