1
00:00:00.050 --> 00:00:06.950
This prepared lab contains four independent device and practice-PC pairs.

2
00:00:15.500 --> 00:00:25.000
On the Dell switch, open VLANs and add the training VLAN with its own ID and name.

3
00:00:35.300 --> 00:00:42.300
Compare the new VLAN with the Dell terminal, then save the configuration.

4
00:01:06.850 --> 00:01:14.000
On Aruba AOS-CX, add the training VLAN through its management page.

5
00:01:21.450 --> 00:01:28.950
Open Routing and add the destination network, subnet mask and reachable next hop.

6
00:01:31.700 --> 00:01:37.200
The Aruba changes remain pending until you choose Commit.

7
00:02:16.050 --> 00:02:22.550
Commit the changes, then review the VLAN and route in Configs.

8
00:02:28.500 --> 00:02:35.500
The connected practice PC should still reach the device after the changes.

9
00:02:42.500 --> 00:02:49.500
On the Huawei router, open Routing and review the independent control route.

10
00:02:56.200 --> 00:03:02.700
Add a different static route using the same reachable next hop.

11
00:03:12.950 --> 00:03:19.950
Confirm the new route in the management page and the Huawei configuration.

12
00:03:27.250 --> 00:03:33.750
On MikroTik, open IP Routes in WebFig and choose Add New.

13
00:03:40.350 --> 00:03:46.000
Enter the destination, mask and gateway, then select OK.

14
00:03:52.500 --> 00:03:58.500
Compare the added route and gateway with the RouterOS terminal.

15
00:04:01.650 --> 00:04:09.650
Choose Save All Configs, then reopen the lab and check each device by name.

16
00:04:52.900 --> 00:05:00.400
Confirm that both training VLANs and all three added routes are still present.

17
00:05:09.950 --> 00:05:16.950
Delete the Huawei route you added while preserving the independent control route.

18
00:05:26.900 --> 00:05:33.400
Remove only the added RouterOS route and keep its control route.

19
00:05:49.600 --> 00:05:56.600
Check both terminals to confirm that only the selected routes were removed.

20
00:06:07.650 --> 00:06:15.650
After verifying the selected removals, use Save All Configs again to preserve your changes.
