Aspiring network professionals should watch the video and practice its content. This will help you troubleshoot real-time problems effectively.
Thanks for your comment 👍
this is one of the best explaination. thank you Sir
You are most welcome
You made all those topics in one video awesome ❤
Glad you like them!
Good Work Bro🎉
Thanks 🔥
Owesome toppic for learning prospective 😊 Thank you Sir
Most welcome
Really very helpful, hope will see more videos with more advance configuration, if possible please make one video on data center devices like NEXUS from sctrach.
Thank you very much
Sure I will
Hello sir I complete the whole senario by myself and then I realized the connection between servers and clients are ok and we can replace the server and client place with each other and then give service like DNS and AAA and .... to the clients but the problem was ospf neighborship so we can replace ospf with static routing I try it and the connection between two branch got ok
Good
Thank for this senario that was really helpful for me 🙏
@amirking5396 can you share me your topology?
Kindly, Share your Demo if possible. advance thanks
Hello PM Networking,
Thank you for this video. I learned some new stuff as I followed the video. I tested it on Packet Tracer and I got the same error of the bouncing OSPF neighbor adjacency between Router1 & Router2. I removed the "default-information originate" command in Router1 and the OSPF adjacency became stable. I tried removing the said command because I had experienced a similar error with tunneling and the cause was route recursion (that the router's own WAN route is being advertised back to it).
Thanks for sharing feedback
❤thanx for good knowledge and explanation, thanks pro
Most welcome 🙏
This video was a good refresher and well taught! Thank you!
Glad it was helpful!
Wow!🎉
Good video Please more such topics, please make project like Bank management, hospital management and small office management
Noted
Sir your video is very very valuable for student ,NO doubt your knowledge is very stronger SO i requested to u Sir if possible please speak slowly as well as do Lab
Noted and thanks for sharing feedback
much needed tutorial for me. but again You missed out a firewall here. would have been great with a firewall. anyway thanks for this
Sorry about that
@@PMNetworking could you please make this same scenario with ASA firewall standby and active and failover, and also add IP phones.
This tutorial is superb.
@@thepuldarshana9056 sure
Nicely done. However, I would recommend IPsec as opposed to GRE, although IPSec configuration is not covered on the CCNA exam.
Sure, this is for beginner network engineer
Nice LAB. Why is clock rate not configured on DCE interfaces? Any particular reason?
No
Hi SIr, Very good video.. Can you also do a video if the traffic is going into the firewall form distribution switch before going outside to the router via a portchannel
Sure, I Will.
sir, ye sab jo aap ne iss video mei bataya ye ccna mei padaya jata hai ya ccnp mei?
Thank u for this lesson
You are welcome
Can we use bgp in this scenario on all serial interfaces
Yes
Please sir make a video like suppose there are two routers in site A and 2 in site B and one ISP router how to configure that
Please sir make a video like suppose there are two routers in site A and 3 in site B and one ISP router configure that
according to your design, Is it possible to ping with 2 separate VLANs ?
Yes
sir can you configure a ASA firewall as fail over and set a DMZ for those servers please ?
Noted
I notice that you are the only one who responds to the comments, I have a question, I always see topologies of this type and I see that they do the routing by imagining the scenario but in a CAMPUS LAN NETWORK I ONLY SEE MORE SWITCHES THAN ANYTHING ELSE I DON'T SEE THAT OF THE I only see DEEP ROUTING on the ISP side, but the internal routing of a LAN IS DONE BY THE CORE OR DISTRIBUTION SWITCHES. What can you tell me about this?
because I have seen all your videos and I have learned the OSPF AREAS AND ALL THAT but I have never seen a CAMPUS LAN topology SEE THAT ABOUT THE AREAS, IT IS ONLY FROM THE ISP THAT DOES SO MUCH ROUTING
Watch switching videos
Real time means you have to open router then configure right,,just asking ...every one want to understand in real time where we have to configure it then uses..correct me if I m wrong
Yes
@PMNetworking pls tell us do you have any other session which is done in real platform and pls suggest anything to understand fully ospf
need to name the router id other than the ip address of tunnel interface to eliminate recursive routing error on OSPF so the routers can advertise tunnel network on each other using the GRE tunnel. the purpose of default route on the routers is to keep the tunnel interface up.
Yes,
Would be better to mention the router and switch models. Every router doesn't have serial ports. I am just learning, so really don't know if in the topology, se0/0/0 is actually g0/0/0 or not. In packet tracer there aren't many options for routers with serial ports.
Instead of serial, you can use any others
yes some more sir
Thanks for acknowledgment
Why you configure in ospf the vlans as a passive interface?
To stop hello message
Sir initially how both multilayer switches was reachable with out connection
Through access layer switch
Default information originate is it mandatory because you created ip nat inside , ip nat outside after the command
Yes yes
Thank U so much. Could you Pls Replace 2 DSW with 2 Routers and configure sub interfaces and Apply HSRP in New video.

Hola, se podría configurar EtherChannel en esta topología ? En donde se lo aplicaría ?
Saludos desde Ecuador
Yes you SHOULD always use it, Where as using HSRP on switches will get you FIRED on spot 😂
After following GRE Tunnel configuration, 172.16.1.x keep flapping (up and down)
Could you please share the running-config of the router and switch?🙏
Now I Don't have topology, I will check
do routing in internet router(middle router) after that two different site ping with each other
You are not allowed to configure internet router😊
40:52 Nat configuration
49:55 Configuration of 2nd branch
i need the 3 layer only for internal server of any organization with different departments IT , Sales , Marketing and administration so please help me to get the desing
Noted
Why have you not used etherchannel between distribution switches
We should use it
I was also wondering about outside NAT.
Thank you
You're welcome
sir, why do you remove OSPF neighbour from core switches ? it is not clear for me. what is the reason ? thank you
I just wanted ospf neighborship between switch and router.
thanks
Welcome
Why I can not configure gre tunnel in my packet tracer? It is just giving error whenever I type "int tunnel 0".
Please help
Change the router
@@PMNetworking thankyou i will try this set up with different router. I was using 2621XM router
Please make video on IP Addressing and Subnet mask
Noted
can i get the file for this network
Hello sir am interested for online CCNA class
Batch is starting from 1st Jan 2024.
plz do one lab with ip-sec vpn
Noted
is this Lab available to download ? to follow and practice
No
Nice can you teach?
I can
@@PMNetworking can I have your number boss.
Where is the topology?
?
where is the file
Which file?
Master please when you configure the core router for the servers, you mistakenly type an error, instead of 255.255.255.255 you type 255.255.255.2520. Overall is really interesting. Have a blessed day.
Thanks for sharing 👍
where topology
What a horrible way to configure HSRP on Cisco switches, do you even know that the way you used will make your network terrible??? Do you even know what this virtual ip does, rather on router you using over switches 😂😂😂😂 ,
Thanks for watching
in router 2 , you didnot enable ospf for 101.1.1.0 network .
Ohh, I have to check it
@@PMNetworking sorry i was wrong there is a default route already 🙂. In my lab the tunnel is not stable its doing down again n again. 😢
Please sir make a video like suppose there are two routers in site A and 3 in site B and one ISP router configure that
