Real-Time Network Configuration For Network Engineers | VLANs, DTP, HSRP, OSPF, NAT, VPN

[@pascalemmanuelhaba3576]

this is one of the best explaination. thank you Sir

[@PMNetworking]

You are most welcome

[@sandipanaec23]

Aspiring network professionals should watch the video and practice its content. This will help you troubleshoot real-time problems effectively.

[@PMNetworking]

Thanks for your comment 👍

[@wintersolstice3573]

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).

[@PMNetworking]

Thanks for sharing feedback

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

[@PMNetworking]

Good

[@amirking5396]

Thank for this senario that was really helpful for me 🙏

[@ahmadmusa3747]

@amirking5396 can you share me your topology?

[@md.alaminhossain2767]

Kindly, Share your Demo if possible. advance thanks

[@lovenature3658]

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

[@PMNetworking]

Sure I will

[@phpBasics]

Nicely done. However, I would recommend IPsec as opposed to GRE, although IPSec configuration is not covered on the CCNA exam.

[@PMNetworking]

Sure, this is for beginner network engineer

[@AliAhmed-sz1li]

You made all those topics in one video awesome ❤

[@PMNetworking]

Glad you like them!

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

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

[@PMNetworking]

Sure, I Will.

[@Simplyanthonyr]

This video was a good refresher and well taught! Thank you!

[@PMNetworking]

Glad it was helpful!

[@thepuldarshana9056]

much needed tutorial for me. but again You missed out a firewall here. would have been great with a firewall. anyway thanks for this

[@PMNetworking]

Sorry about that

[@thepuldarshana9056]

@@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.

Thank U so much. Could you Pls Replace 2 DSW with 2 Routers and configure sub interfaces and Apply HSRP in New video.

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

[@PMNetworking]

Watch switching videos

[@ankitsingh4296]

sir, ye sab jo aap ne iss video mei bataya ye ccna mei padaya jata hai ya ccnp mei?

[@AliAhmed-sz1li]

❤thanx for good knowledge and explanation, thanks pro

[@PMNetworking]

Most welcome 🙏

[@jawidsaboori762]

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.

[@PMNetworking]

Instead of serial, you can use any others

[@alwinposadas3712]

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.

[@PMNetworking]

Yes,

[@galaxyspace4077]

sir can you configure a ASA firewall as fail over and set a DMZ for those servers please ?

Yes

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

[@TheDenis3212]

yes some more sir

Thanks for acknowledgment

[@matthewespinosa7491]

Hola, se podría configurar EtherChannel en esta topología ? En donde se lo aplicaría ? Saludos desde Ecuador

[@jalalhaider83]

Yes you SHOULD always use it, Where as using HSRP on switches will get you FIRED on spot 😂

[@JITENDRARAWAT-x2z]

I was also wondering about outside NAT.

[@praohyderabad1750]

Default information originate is it mandatory because you created ip nat inside , ip nat outside after the command

[@PMNetworking]

Yes yes

[@fatmaelsayed319]

Why you configure in ospf the vlans as a passive interface?

[@PMNetworking]

To stop hello message

Why have you not used etherchannel between distribution switches

[@PMNetworking]

We should use it

[@thepuldarshana9056]

sir, why do you remove OSPF neighbour from core switches ? it is not clear for me. what is the reason ? thank you

[@PMNetworking]

I just wanted ospf neighborship between switch and router.

[@patukifaletiute5816]

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.
