Hi I am having trouble configuring Cisco 1921/k9 upon oa factory reset the internet work then it stops working I have cable internet and spectrum is the isp the modem isn’t issuing an ip to the router

[@enkaan1676]

Sorry I’m a beginner. What software are using for this simulation.?

[@ITSolutionsNetwork]

It's an eve-ng pro.

Top Video… thx 🙏

[@ITSolutionsNetwork]

You welcome.

[@h.mtechchannel]

hello sir good job . please can you help me ? When i configure my Cisco 800 in interface fastethernet it show: ip address may not be configured on l2 links

[@ITSolutionsNetwork]

Thank you for the relevant question. Yes, the Cisco 800 series only has one routed port, and the rest of the ports are L2 ports. You'll need to configure the interface VLAN instead of the ethernet port and then use switchport access vlan command to assign that VLAN to the L2 port.

[@h.mtechchannel]

[@linkah]

I set the wrong interface to outside, so now they are both outside, and I can't get it to set to inside, any idea how to fix this? Tried doing clear IP nat etc but couldn't figure it out.

[@ITSolutionsNetwork]

You just repeat the correct config and it’ll overwrite the bad one. Go to inside interface and type “ip nat inside”.

[@linkah]

@@ITSolutionsNetwork Actually had to do "No ip nat outside" then "ip nat inside" because #Cisco.

[@ITSolutionsNetwork]

@@linkah There was no need to do "no ip nat outside". The "ip nat inside" overwrites the "ip nat outside".

[@linkah]

@@ITSolutionsNetwork I tried but it kept saying "ip nat inside % Interface is outside enabled." and wouldn't let me over-write it. I think the issues is I'm using an older 1941 K9 router. I'm sure they have updated the cli to allow over-writes since then.

[@akinwalefemi8728]

very helpful. i appreciate that

[@scwallac]

This was outstanding, thank you. I think for a typical router, you would also want to setup NTP as well, right? Is there anything else that would be a good idea to setup? Maybe syslog?

[@ITSolutionsNetwork]

Many things are suitable to be configured, but it mainly depends on the end goal. For this video, the goal was to get you up and running with Cisco and have Basic (minimum, I would say) security in place. NTP? Sure, if you need it. Syslog? Again, sure if you need it.

To be used as manually configured IPs for switches, Access Points and some IoT devices if you need to.

Great video i was able to follow and implement it very well. However when i did a speedtest on ookla, speed was about 3 times slower than my edgerouter... would you be able to advise?

[@LetsBland9411]

That's a very nice and detailed video sir but you didn't specify where the IP addresses are coming from to beginners .like we're is the defaul-router coming from

[@ITSolutionsNetwork]

It's coming from the ISP. Whenever engineers are being tasked to configure a Cisco router, they usually have IP addresses from the requester, supervisor, or any different kind of source. In this scenario, I'm the creator of a virtual ISP; hence I had an IP address and put them on the topology, and then I used it in the configuration.

[@LetsBland9411]

@@ITSolutionsNetwork 🙏🙏🙏 thanks sir it's now making sense..so

[@LetsBland9411]

Do you mean the ISP are the ones that provide only one ip address (public address) and all those gig 0/0 gig 0/1 interfaces you configured are generated by the company supervisor? My next question is let's say you are the supervisor ...under DHCP on network will you copy paste the address for gig 0/1 and paste it on network? And on default- router will you copy paste the address for gig 0/0 and paste it on default-router…? Or you generate them landomly?

[@ITSolutionsNetwork]

@@LetsBland9411 I don't have Gig 0/0 and G0/1 in this topology. The answer to your DHCP questions is no and no. The DHCP config includes network, Router and DNS options, and excluded IPs. All these are picked when you architect the network, once you choose the subnet and router IP, then you have enough information to configure the DHCP Server, you just need to know how to configure it.

[@ahowardcg]

what router image was that in eve-ng? you have the name? there is so many damn files and im not sure what half of them are

[@ITSolutionsNetwork]

I don't remember which image did I use in this specific scenario, but I know this image works on eve-ng. csr1000vng-universalk9.16.03.03.Denali

[@nirmalunagar]

after assigning ip address to gigabit Ethernet 1 I cannot ping ISP ip. please can you tell me what should be issue?

[@ITSolutionsNetwork]

There can be lots of thing and without knowing what troubleshooting steps you already have done, or which configuration or operation mode you already have confirmed, it's really hard to say what could be the wrong.

[@nirmalunagar]

@ITSolutionsNetwork it has been resloved sir thanks. The 2nd is Im using NAT interface in the GNS3 vm, and my topology is cloud > router > firewall. After configuration, I can ping my windows from firewall but can't ping from windows to the router inside the interface. Please, what should I have to do?

[@ITSolutionsNetwork]

@@nirmalunagar If at any point you are trying to ping two different subnets, they have to know how to reach them on the routing table level. I'll have to make sure windows knows how to reach that specific interface and the firewall is allowing the traffic.

[@nirmalunagar]

@@ITSolutionsNetwork I have simply followed your video which is cisco router config. I have done that way. and from firewall I can send traffic outside but can't ping from outside to router inside interface

[@ITSolutionsNetwork]

@@nirmalunagar My video doesn't include windows routing. Anything L3 device between your windows and firewall should know how to reach that specific firewall interfaces in terms of the routing. You check that and make sure they know.

[@yurahovhannisyan735]

nice video. if we dont have dns ip address can we do dns-server dhcp ?

[@ITSolutionsNetwork]

What exactly do you mean by dns-server dhcp?

[@yurahovhannisyan735]

@@ITSolutionsNetwork i mean whenever you connect to the internet and you dont have ip address of the dns server but you need that ip address is it a way to get the ip address automatically

[@ITSolutionsNetwork]

@@yurahovhannisyan735 Yes. Whenever you use the DHCP client on the interface, the router will automatically get DNS IP addresses and the default gateway from the DHCP.

[@jaroo25041980]

Super, but how to connect to Isp with dhcp, how to check dhcp default gateway and dns

[@ITSolutionsNetwork]

Don't configure a manual IP address on the interface and static routing. Instead of: interface gigabitEthernet 1 ip address 12.34.56.2 255.255.255.0 ip route 0.0.0.0 0.0.0.0 12.34.56.1 Do this: interface gigabitEthernet 1 ip address dhcp ip route 0.0.0.0 0.0.0.0 dhcp Sometimes default route with DHCP is not necessary. Also, the interface DHCP client will get and use DNS settings as well. However, you don't need it.

[@jaroo25041980]

why isp address is set to no out ?

[@ITSolutionsNetwork]

It's not "no out", I missed the character "s". I tried to enter "no shut". So when I clicked a TAB to finish the command, it didn't finish and moved the line up, which feels like I hit the enter, but I didn't. Then I deleted it and entered again the correct command, which was "no shut", short for "no shutdown" to enable the interface.

[@infonetwork2062]

Very nice video, but you are only communicating to core professionals. Too fast because novice won't even understand more than 25%. TOO FAST

The diagram and configuration for the Gig 1 and Gig 2 are mismatched.

Hi there, thanks for pointing that out. However, I'm checking at 1:15, and it doesn't look like a mismatch. Gi1 is an outside interface, and Gi2 is the inside interface with corresponding subnets, just like in the diagram. Where exactly did you see a mismatch?

Why are all tutorials IPv4 not IPv6? We will never transition to IPv6 this way

[@dpactootle2522]

I always thought that using and memorizing hundreds of IOS arbitrary commands to configure Cisco routers/switches was the stupidest and most moronic thing ever, and I still think so. Why would techs have to memorize all this garbage instead of using GUI interfaces in the 21st century? there is plenty of memory and bandwidth nowadays. IOS commands are prone to mistakes or you might forget a configuration parameter or whatever even for simple tasks, let alone complex setups. I cannot understand why the fuck do people still need to memorize all that crap instead of just clicking check boxes and inputting parameters in a nicely designed GUI interface all the time. I know Cisco routers have GUI interface programmability, but why do they still require techs to learn all those stupid commands? Is it just to make them feel smart by memorizing a bunch of crap, or to make them exercise their memory, or to make them waste half their life, or what?

[@ITSolutionsNetwork]

I totally get where you're coming from, and it's a valid point. Using the CLI over a GUI can seem a bit old-school, but there are some pretty solid benefits to it, at least to me. Precision and Control: The CLI allows for more granular control over the configuration. It's like having a detailed map instead of just the main roads. You can tweak and adjust settings to a very precise level, something that's often harder to achieve with a GUI, and GUI with every settings in it can be very overwhelming to even look at it. Speed: Once you get the hang of it, CLI can be much faster. It's like knowing the keyboard shortcuts instead of navigating through menus. For tasks that need to be repeated or automated, CLI commands are a lifesaver. There is no GUI faster than CLI. Scripting and Automation: CLI commands can be scripted and automated, making repetitive tasks or large-scale deployments much easier. It's about working smarter, not harder. Even for a small tasks, you can copy/modify/paste config via CLI, which I usually even do for EdgeRouters or Mikrotik, even though they have pretty usable GUI. Consistency: The CLI is a common language across many devices and vendors. Once you learn it, you can navigate various systems with ease, unlike GUIs which can differ significantly from one platform to another. While GUIs are definitely user-friendly and visually intuitive, the CLI remains a powerful tool for those who need that extra level of interaction with their devices. It's not so much about memorizing commands as it is about understanding the language of your network. And don't worry, even the most seasoned pros use help commands and google; it's all part of the process. Hope that helps clarify why the CLI still has its place in the tech world!
