Hi! First of all, I want to thank you for all the explanations you provide step by step on every exercise! You have no idea how much you are helping me and I'm sure a lot of other people!! Regarding this lab. I don't understand how it worked for you to ping from PC1 to PC3 for example without the command "switchport trunk allowed vlan 10,20,30,99" (minute 8:36). You put "switchport trunk native vlan 88" on interface g0/1 on the switch. All 3 PCs are in different VLANs. Strange that even the exercise doesn't specify this so I'm guessing something isn't clear for me. I followed the steps from the lab, and had 100% correct but still no pings were working. After that, I watch what you did differently. Looks exactly the same. As soon as I put the command that I said in the beginning everything worked. I don't understand the concept of why it's working in your case. Thank you again for all the effort you put into all your videos! I wish you all the best!
Update: I did the lab again from 0 and this time it worked. I figured out why it was showing 100% complete and it was wrong as well. It was because I allowed only vlan 88 on trunk by inputting the commands in this order(I wanted to put only the 2nd command but couldn't remember to correct format at that moment): S1(config-if)#switchport trunk allowed vlan 88 S1(config-if)#switchport trunk native vlan 88 I remembered because I also did the command "show interface trunk" and was thinking wrong about the issue. Now it all makes sense. Have a great day! (^_^)
Thank you for the video. What is the configuration from Router to HQ? Seems the g0/0 has an IP address 172.17.25.2 and the server is on 50 network. So does one of the HQ interface is configured for the 50 network?
In the cloud exist a router with tow interfaces, first interface with 172.17.25.0/30 network connected to R1 and second interface with 172.17.50.0/24 network connected to server
