*## THIS VIDEO WAS ADDED IN 2022 AS AN UPDATE TO THE COURSE ##* Day 11 of the course used to have 1 lecture video, but I remade it and split it into two parts: Part 1 - Routing Fundamentals: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-aHwAm8GYbn8.html Part 2 - Static Routing (this video) Part 1 covers basics like how to view the routing table, Connected routes, Local routes, and route selection (most specific matching route). Part 2 covers how to configure static routes, giving a router the ability to forward packets toward destinations that are outside of the router's own connected networks. Old Day 11 video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-M7F_ljN0IdA.html
Hi sir Jeremy, where can I find the Lab in these 2 updated lessons? Is there new Lab for these 2 lessons or the old Lab still the exercise in these 2 lessons? Thank for the answer.
@@janearltocson2965 i believe the google drive repository that jeremy provides us with for this course has all of the latest PT labs and flashcards. iirc i dont think there are any new labs for day 11 that go along with the new videos.
@@chindianajones3742 Thank you for the answer sir. Last question sir. So, after this 2 lessons I will proceed to that Lab 1 published 3 years ago right sir?
Just wanted to share... passed my CCNA first try yesterday!! Thank you Jeremy, I watched and worked through your entire free course and prepped with Boson ExSim tests. For everyone on day 11 (part 2) of their journey, stick to it and keep up with the labs and flashcards!!!
@@edriceedesign 4 years of IT profiled High school, 3 years in "weekend" College. Had troubles finding the job. Made a professional CV photo, marked on my CV that I'm learning towards my CCNA, passed ITIL v4 funded by college. Got an interview, got asks like: -What is PoE, how u can use it, what devices, -What is auto-negotation, what happens when it's disabled, -Difference between Intel and Xeon, -How does dual-channel works, -What is routing, -What is access mode, what is trunk, And more networking stuff which I don't remember, but nothing really hard. When i asked my interviewers about the question and why They picked those (which doesn't fit the job so much), They told me, that if i knew that stuff I'm gonna be able to learn new, because that shows I'm learning by myself.
This was by far the hardest section so far. Your teaching is absolutely university level, I can't thank you enough for using colours on the router interfaces. Thank you again!
Dude, yesterday was the day that i read the holy words: "Congratulations you passed the exam" Now i'm going into CCNP ENCOR. Thank you for your content :) i really enjoy every second.
Jeremy, I would like to Thank You for this course! From 0 knowledge to PASS in first try! One month and two weeks, 4-5 videos everyday, Boson ExSim questions. This helped me a lot with my studies. I would recommend this course to everyone! One important thing - guys, do labs! This helps to better understand the material!
Im going through 3 lecture/labs a day right now, and really enjoying it, the plan is to pass the exam in a similar timeline! :) how much time did you spend on Boson? and was it worth the price tag or do you think I can save the money and just hit the flashcards harder lol also, CONGRATS!!
Followed through the series and passed CCNA exam. I have and will always recommend this channel to every person interested in getting the certification. Looking forward to CCNP videos .
just passed my CCNA exam on first attempt, very informative, i recommend everyone preparing for your CCNA to study and watch all the videos from here . thank you @Jeremy's IT Lab 😇, we start the CCNP Journey
was the lab questions in exam easy? and what was it about? and how did you study? was watching his videos and doing the labs and flash cards enough to pass? or did you used other sources
Having split the lecture into 2 parts makes learning the Routing concepts very easy to understand. I had to admit that the 1 lecture video on Static Routing was not as easy as the 2-Part videos. I'd always come back to watch your free CCNA videos if I need to refresh on certain topics.Thank you very much for your time and effort you put into this.
Gracias Jeremy, no soy de habla inglesa, pero con subtitulos tus videos se entienden perfectamente. Yo aprobe mi examen CCNA hace 5 dias y mucho le debo a tus videos explicativos, las practicas con laboratorio y las tarjetas flashcard. Este contenido es muy completo y recomendable para aprobar el examen. Nuevamente, thanks for your help.
Thank you for the great instruction/content. 24:50 pointing packets out of a broadcast interface without explicitly defining the next hop is slightly undesirable as it will cause this device to use extra cpu/memory to arp for all unknown destinations that will likely end up pointing to similar L2 addresses.
if anyone is wondering why he used the 'do' command in showing the ip routes, it's because the do command helps you to run privileged EXEC mode commands from global configuration mode. Thus "do sh ip route" allows you to run the "show ip route" command from global configuration mode.
Man after these two parts I have some much stuff to compile in my head now, probably asking a lot of questions that have videos later on. Really hard to grasp all this architecture at first, but hopefully in the future all of this becomes easy to navigate through and understand.
Hello everyone, so far the course is so good and understandable. if anyone has started preparing for the CCNA. Please let me know let's study together 😀🤝
Great videos and timely for me because I've been looking at this topic recently. I don't agree with your statement that neither the next-hop or exit-interface option is better in the ip route command. In an Ethernet LAN (as opposed to a serial point to point), Proxy ARP is less efficient for the forwarding router. Because the forwarding router sees all destinations matched by the routing entry as local, it will use ARP to find the MAC addresses - the peer router (next hop) replies to the ARPs with its own MAC on behalf of the real destination IP addresses. This means that the forwarding router will potentially have a large ARP cache containing entries for all possible destinations. This may be inefficient and impact performance. If, instead, the next-hop option is used, the forwarding router need only know the MAC address of the next router.
Jeremy thank you so much i just passed my ccna in first try. You helped me so much i got 3 labs 2 is from routing and other one is from nat believe me in ccna exam they will ask you anything so be prepared for it and remember don’t give up.
@Jeremy's IT Lab I believe the wording for configuration command of a static route should be "ip route network-address netmask next-hop" ip-address is not explanatory of what is needed in the command.
The routing process starts with the host that creates the IP packet. First, the host asks the question: Is the destination IP address of this new packet in my local subnet? The host uses its own IP address/mask to determine the range of addresses in the local subnet. Based on its own opinion of the range of addresses in the local subnet, a LAN-based host acts as follows: Step 1. If the destination is local, send directly: A. Find the destination host’s MAC address. Use the already-known Address Reso lution Protocol (ARP) table entry, or use ARP messages to learn the information. B. Encapsulate the IP packet in a data-link frame, with the destination data-link address of the destination host. Step 2. If the destination is not local, send to the default gateway: A. Find the default gateway’s MAC address. Use the already-known Address Reso lution Protocol (ARP) table entry, or use ARP messages to learn the information. B. Encapsulate the IP packet in a data-link frame, with the destination data-link address of the default gateway.
I have a question regarding the last quiz question: Wouldn't it also be possible to add one route via R1/4? I.e. 192.168.0.0/19 192.168.13.0? Sure that wouldn't be the shortest route to 192.168.24.0/24 but it still would give reachability without bricking something else, wouldn't it? And when the question is, how many routes do i need, I want to get as low as possible, don't I? When thinking about it, when we assume that the other routers have a full routing table, we would be able to get it done in one route right? I.e. delegate it to R1 for example.
I'm confused rn. Default gateway is the router right ? If a packet is sent outside the network, the packet will be transmitted to the "default gateway" and then to the next-hop (if static route is configured). Then how is it that default gateway and default route the same? When the definition of default route, is the route where the packet is sent if the router has no matching routes in its table anymore ? Can someone pls enlighten me.
Modem connects a network to the telephone network (dsl) or to tv cable (coaxial), and then the connection is to a router. Router connects LANs and Wlans to internet network using utp, cat6, w
I find it funny on how the video course progresses (gets more heavy on info) the less likes and comments there are, are people dropping out after 1 week? lol, c'mon.
Hey Jeremy, so far I have been reviewing every single flashcard everyday at night, I've wrote over 40 a4 pages. usually I get 2 to 3 cards wrong by deck. and complete the labs as you lecture them. If I keep this up do you think it is enough? Basically I'm following this course very VERY strictly . Thank you so much for doing this for free, you're the best!
Keep in mind the people who make those practice exams don't have anything to do with the people at Cisco who make the CCNA. They're a separate company licensing the Cisco name.
Hey Jeremy, it's an amazing video and you make the topics very easy to understand. Thank you very much for your time and your work. I just have one question about configuring the second rout on R2 24:45 (exit interface with the next hop). I entered the command exactly like you did, but it says "% Invalid input detected at '^' marker." and then it points the ^ marker to the beginning of the ip address of the next hop 192.168.24.4 Do you know why is it showing this? In Packet Tracer I'm using the Cisco router 2911
Can you get grammarly to write my comprehensive english essay test too? That would be great. I really need to catch up on my essay entitled, "I'm just a lazt F#$%"
Is it better practice to specify both the next hop and the interface when declaring static routes? Or why would I not just specify the next hop? What I mean is, is there any point in going through the extra trouble?
I think it the only difference is that when you specify the interface it makes it a directly connected route when it actually isnt .......still learning myself.....
00:24:22 "ip route ip-address netmask exit-interface next-hop" doesn't work, does it? You need to do "next-hop" and "exit-interface" separately right? (in Packet Tracer at least, it gives me a "Invalid input detected")
for quiz question #5, why would router 3 need to know both pathways to R2. Wouldn't 3 connections achieve the same outcome in terms of connectivity to all networks? thanks anybody
Which trunking protocol(802.1q or ISL) does RAPID PVST+ support? As you mentioned pvst+ supports dot1q. Is rapid pvst+ similar like pvst+. Please I need your answer 🙏
23:01 i have one question, so in default route, there is is a image where R1 is connected to internet as a default route to ip, how do we find out the IP address in real life practice which in this case was 203.0.113.2 bcoz in real life we wont be given with this , there will be something else, then how to find the default route internet ip and configure?
I'm pretty confused by the routing diagram in this video. Are the IP addresses of R4 interfaces supposed to be 192.168.4.X or 192.168.34.X? The ".4" is the last octet for the interface IPs, right? So then that means the interfaces are on the .34 network? Then what does the 192.168.4 network belong to? Because of the placement of the IP addresses in the diagram, I really cannot tell what entity they belong to.
Okay I think I understand it now, it's just sorta weird looking at it because the whole thing is crammed together. But the .4/24 network is a separate network connected to R4 that PC4 is on, but is not necessarily the same as the R4 IP addresses. Is that correct?
Alright I'm confused again, so do the routes themselves have their own network addresses? So G0/0 on R3 has an IP address of 192.168.13.3, correct? I was under the impression that R3 would be the only devices with a .13 network address, but I guess R1 has a .13 network address too on G0/0. Is that right?
Okay I THINK I understand it now, so the connected interfaces share the same network address, so in theory each different interface on a router would have a different network address. I think. I don't know how this would look in larger networks, but this is what I've pieced together. Thank you everyone for following the ongoing saga of me slipping further into madness
Can someone please tell me why my router doesn't show local routes in the routing table? Only connected routes when I first configure an ip. Everything functions fine, its just bugging me! I cant seem to find an answer from Google for once...
Hi Jeremy! You say that all routers dont need routes to all networks in the path to the destination but when I dont assign static routes in the path to the destination, I cant ping the PC in the destination. Anyone can help me about this? Thank you.
One question, so you said let's consider they know the MAC address for the whole neighbouring networking, but what about the IP address.. i mean we did configure them but do routers know it? do they find out by ARP requests too? Great video tho, very simplified!
why does the static ip command change from 192.168.4.0 to 192.168.1.0 in the ip address portion of the static ip command on r4? the next hop is still in line with the other configurations but im trying to figure out why it goes from ip route 192.168.4.0 to ip route 192.168.1.0 once we get to R4. Thanks!
I have one question if anyone can help with. In the last lesson it was stated that a router will drop a packet that none of its routes match the destination IP address. Is this only true if there is no default of 0.0.0.0? Also great video series, just caught on this one question. Thanks!
By doing static routing we wish to define the route for two LANs which are not directly connected. Let's call them LAN1 and LAN2 Each router needs to know: 1. If I receive a packet destined for LAN1, where should I send it? 2. If I receive a packet destined for LAN2, where should I send it? Now let's look at the example given at 17:25 If you focus on R1, the first row says: If I see a packet which matches 192.168.1.0/24, I should that packet to the connected interface (that is G0/2), there is already a rule for this as it is a connected route. This was explained in the previous video. Note that there are many IP addresses which could match this rule such as: 192.168.1.10, 192.168.1.200 etc. as 192.168.1.0/24 defines a whole range of IP addresses. Row 2 of R1 in the chart says: If I see a packet which matches 192.168.4.0/24, I should forward that packet to R3 using IP address 192.168.13.3 - this address is the next-hop, the address for the next router you should send it to so it can eventually make it to its final destination. If any of that seems unclear (assuming I explained it properly and intelligibly), I would recommend having a look at some of the earlier videos covering subnet masks, LANs and routers in case there was something there which didn't fully click. Let me know if anything about it is unclear still.
