awesome, good to know i wasn't the only one having connectivity issues. I watched your vid to double check my work and turns it you had the same ping results I did.
me too, spend 30 mins trying to troubleshoot ospf, then i looked for the video to find out the issues is related to the ISP routers. Always great videos, very informative
I was able to do both pings in the Connectivity step. I think the issue might be when configuring GRE Tunneling in the video, he issues no shut commands on both routers in scope as the final commands before moving on to the next step. I didn't have to do this as my interfaces were already up. So issuing the no shut commands were not necessary and might be preventing the 2 pings from going thru successfully.
In the real world 100% + no successful ping = 0% To make pings work call the ISP to verify PPP/CHAP settings. :) I FOUND THE SOLUTION!!!! In this case the ISP username values in the instructions are incorrect, try using ISP2 and ISP3 instead of "ISP-2" and "ISP-3". I guess studying for CCNA is not difficult enough, pulling my hair out while troubleshooting packet tracer/GNS3 is just one of those things I'll have to learn to love.
Bro, i loved this PT! thanks, and it was very challenging, through your help i recalled the dhcp and ssh commands =) anyway, surely my mistake, i advertised ospf networks for GRE tunnel using 10.1.1.1/30 and 10.1.1.2/30 instead of 10.1.1.0/30, as u did in the right way =) my pings were successful because of this error? xD
I completed this lab, getting 100% score, but serial interfaces conected to ISP-2 and ISP-3 were up/down. As result of this the tunnel is up/down, of course. It seems to me there´s some misunderstanding with PPP authentication. I did debug negotiation and showed that authentication was unsuccessful. I am lost as we cannot access the peers to check ppp.
Hello dear, i have a problem accessing the material in my account in Netacad.. the modules are not showing as usual, there is no direct way to reach the support admins to ask for help, can you help with any solution?!
@@TechAcad otherside is ISP side which is locked No CDP discovery Disabled but link lights are green ? Even if i copy paste whole configuration Challenge is 100% Complete But still cannot ping nodes. Please guide

You've helped me understand CCNA way better than any of my professors ever did...thanks so much!!
Glad it helped!

Great job!
I completed this lab and i have connectivity to dns server from all Pc’s. Thanx for video
Thank you dear Frend.
Works, try to check static then dhcp option in PC's after DHCp configuration!
Goodness me. I got all the right configs and still ended up with no connectivity, you saved me from breaking another window, thanks!
Thank you so much my dear Friend for your great support...
Tech Acad Can you pm me your contact details? Salam my brother
THANK YOU FOR THIS! I'VE LEARN A LOT FROM YOUR VIDEO!
Glad it was helpful!
thank you so much my friend. You are awesome!

Does not the GRE tunnel 10 need to be configured with an IP address as well? (I see the tunnel source and tunnel destination values set correctly).
you didnot do cmd (tunnel mode gre ip ) on HQ router . this could be the problem of not ping
the tunneling mode gre ip is usually the default tunneling mode on cisco ios routers..
is this Lab possible in GNS3 ?
Thank you so much!!
Glad it helped!
thank you!!!!

All resources are available in the website. Only make sure that the site is not in under Maintenance.
Its always under maintenance 😃
Maybe its temporary..
Anyways i completed the activity 100% and all PC can ping.. Thank you!
as soon as i put ip address on HQ serial interface S0/0/0, interface protocol turn into down state ? what would be the problem ?
Please configure the both end of the interface.

Please guide
I can not ping from pc2 to dns
You might done some misconfiguration. Please verify the configuration and correct it!
