Hi Keith! You didn't fail me (or us), waiting for this HSRP video since a week ago from my request ("HSRP labs are in my queue") :) thank you, really appreciated!
Great video. I did everything but changed the web server subnert mask. Doh. Great video and great lab. I passed the CCNA but this really had helped my understanding more since pushing
Not until I did "sh cdp nei" on R1 I was able to see where gig0/0 was connected to. I keep forgetting about checking if "IP routing" is enabled!! good lab
Keith, just want you to know that your troubleshooting on this video is helping me work out a problem at home. My desktop randomly wouldn't connect to the wifi, either the ISP router or my hotspot. Every phone in the house, my laptop and the chromebooks all connected without issue. Trace came back with "1 transmit error: code 1231". With the ethernet connected I get a 169.254... address.
So simple... just had to bounce from dhcp to static and back under ipv6 and it finally worked. I greatly appreciate all the troubleshooting that you do, that you keep in your videos.
Here's a good tip in PT. On the end devices (PC, Laptop, Server), go to Desktop, then IP Configuration. You get everything there instead of using the Config Tab!
So I may be missing something, but when you took down MLS1, technically wouldn’t the DHCP server have no connectivity since it was directly connected? Wouldn’t you need a 2nd dhcp server on the other side for redundancy or dual homing it to the MLS2? Am I overthinking this?
Its true that DHCP wouldn't be reachable from any clients after MLS1 was taken down in this demo, but as PC1 and 2 already had received DHCP leases before taking down MLS1, the clients would keep their IP information provided from the DHCP server and therefore not need to make any further contact to it, until the clients leases expire at a defined time (often default expiry time is 86400 seconds / 24 hours), after which the clients would drop the provided IP information and lose connectivity. Unless the clients manually enter their IP information or an alternate path is created to the DHCP server via. MLS2 as you state. tl;dr: If X number of hours went by with MLS1 down, the clients would drop their DHCP lease as well as the provided IP information, and the clients would therefore lose connectivity. Hope this makes sense, happy hacking
Great lab Keith, I enjoyed the challenge! I have a question though... when testing the HSRP by switching off the MLS1 which the DHCP server is connected to, how do the PC's retain their IP addresses when the DHCP server is cut off from the network?
Thank you Clifford Snouck. Feel free to join my Discord sever. Lots of people there helping each other out. Each Saturday at 10am Pacific I hold my "Office Hour" where learners can ask questions about the topics they are studying. Mostly focusing on Cisco CCNA 200-301 topics. Feel free to join us there live if you are available. Here is the link ogit.online/Join_OGIT_on_Discord Thanks again Clifford Snouck!
Hello Keith, could you please explain how were the PCs that are in different VLANs able to contact DHCP server if IP routing was disabled!! thanks in advance
I almost gotta ask, but I feel i know working in the field. Are these problems planned as part of the troubleshooting activity as refresher? Lol I mean realistically all these problems are like exactly what I go through day to day. Fixing every other issue before I can even get to the original task. 😂
Hi Keith, thank you for such a great video! I just have a question. When MLS1 is down and the PC's dont have access to the DHCP server how can they communicate the Web Server?

When I downloaded the packet tracer, the DHCP server did not show the services tab where you would go in and change the default gateways for the various vlans. Am I missing something? I downloaded it twice with the same issue.

That must be frustrating. Have you considered your Java version, that it is up to date? You also may want to uninstall, then reinstall th PT app to see if that helps as well. I wish you the best in your studies.
Did the damn thing and started shutting off the power... guess who forgot to do save running-config :D. Won't do the same mistake twice... oh wait... :D
Once again, another great lab Keith. Really challenged me, and I know I learned and got better today because of it!!!
Thank you Trey Graham for working on that lab! Hands on practice is one of the best ways to build your skills, and get better. Thank you!
Great to have the extra complications in there, good to reinforce the basics before we start building on extra services. thanks, Keith
Thank you Nick

You got it!
Great Keith ... Keep updating us...
Thank you Suraj Rajendra Pandey!

Glad it helped!
Thank you Keith !!
Great stuff, learnt a load and it was fun too!!
Thanks Dude 😄👍
Thank you George Kaimakis!
Thanks Keith. I gave this a go. Great Lab! Dealing with the part before the actual lab objective really got me.
Nice work! Thank you for letting me know you did it.
You are the best ever!!!
Another great one from Keith. Thank you.
Thanks for listening

Hi Keith you are the best lol, thanks very much for help people 🖐🖐🖐🖐Albania ☺️☺️
My pleasure!

Thank you Ltat42!
also something i usually set in PT, options > preferences > use CLI as device default tab
Great content ❤

got it Keith, thanks anyway, your videos and Jeremy's are just unique, and unbeatable
What was Keith's answer? I can't see it here

is it just me having trouble with this pk 7.3.0 v that keeps crashing all the time ...unable to do Keith barker labs
That must be frustrating. Have you considered your Java version, that it is up to date? You also may want to uninstall, then reinstall th PT app to see if that helps as well. I wish you the best in your studies.
Did you say "Sin novedades"? hahaha. Spanish is my native language
Hello Keith what versione Packet Tracker use, becouse this lab i can't open on my pc ? I have version 7.2.2 ,Thenks!
If you download 7.3 it should work fine.
@@lancel9460 thank you

Thank you Alexander Kyumurkov for working on that lab!
Thanks Keith !!!
Happy to do it, thanks for the feedback Ali Hersi.
