    I have been studying for the CCNA for about a year. I have the official text books which I have read several times. I have also spent countless hours going through two video courses (one paid and one free). No matter how much effort I have put into my studies, I just never felt like was getting it. UNTIL I found Jeremy's videos!!!!!! Amazingly clear and thorough explanation of all topics and very useful quizzes to help ensure the main points are understood. I can't recommend these videos enough. I don't think this information is presented in a more thoughtful manner anywhere. Thank you so much for this amazing resource.

    I worked for an ISP for a while but didn't get into the networking side of stuff mostly just installs and a little bit of replacing/adding new equipment. But everything was GUI. I recently went to a different ISP who uses mostly CLI. They use Juniper and so I started doing the Juniper training and learning CLI... as soon as i got to routing and vlans I was lost they don't explain it very well at all. So i came here and have been doing the labs (albeit over and over again to drill commands into my memory). Jeremy gives a good overall explanation and after going "huh" over at juniper, i did these last few videos and went back to the "huh" vid at juniper and went "oooh ok i get it... why couldn't you just say what jeremy said?" These vids while yes they are for ccna, they're helping with my jncia 10x better than the jncia course. THANK YOU JEREMY'S IT LAB!

    • @JeremysITLab
      @JeremysITLab  4 роки тому +3

      Good question! If both the source and destination are in the same VLAN/subnet, the frames don't need to be sent to the router, this is the same for the native VLAN or any other VLAN.
      If the source and destination are in different VLANs/subnets, the frames have to be sent to the router to be routed. Again, it doesn't matter if one of the VLANs is the native VLAN, the behavior is the same.

  • @nkkrishnan915
    @nkkrishnan915 4 роки тому +2

    at 15:56 i think the explanation may not be complete. The switch has no clue what VLAN the traffic is intended for. It does assume that the frame is intended for VLAN 30 and, if the MAC address of the destination PC is not in the cache, may flood the frame to the other ports in VLAN 30. The effect is the same - the packet does not reach the intended destination.

    • @JeremysITLab
      @JeremysITLab  4 роки тому +1

      I'm assuming that there is regular traffic in the network, so the destination PC's MAC address is in the MAC address table. So, the switch knows that the destination is connected to an interface in VLAN10 (because it's in the MAC address table), but the received frame is in VLAN30 (mistakently, because of the native VLAN mismatch), so it doesn't forward it.

  • @zepkid5678
    @zepkid5678 2 роки тому

    Hi Jeremy - On the final quiz Q, your answer was the VLAN does not exist on the switch. My question is around creating the VLAN. In these videos, you create the VLANs on access ports:
    SW(config)#interface range g1/0 - 3
    SW(config-if-range)#switchport mode access
    SW(config-if-range)#switchport access VLAN 10
    If you don't want to create access ports in the first place, can you instead do this by changing the two instances of the word "access" above to "trunk"?

    At 16:04 there is a statement that "the destination is in VLAN 10 and not VLAN 30. So I won't forward the frame". so as per my understanding till now if the frame is unknown unicast or broadcast then it will forward the frame towards VLAN 30 but as the destination IP address does not exist in VLAN 30 there will be no response.
    From the statement given it seems the switch will no forward the frame but as per the above details it has to forward in frame in above case.
    Correct me if I am wrong. Thanks.

    Hey Jeremy, in the example at minute 5:43 when the two PCs communicate within the same VLAN/subnet, why doesn't go PC > SW2 > R1 > SW2 > SW1 PC? Instead, it skips the router and goes straight from SW2 to SW1. Are we assuming that the MAC address is known already? Could you clarify that?

    • @JeremysITLab
      @JeremysITLab  4 роки тому

      The two PCs are in the same subnet, so there is no need to send the traffic to a router. Routers are used to send traffic between different networks/subnets. The sending PC will use ARP to learn the MAC address of the destination PC.

    Hi Jeremy,
    First of all thank you very much for your wonderful course.
    I have a question here, 15:25, you set an example frame sent from PC on the right side VLAN10 to the left side VLAN10, and as the trunk port has been set up between SW2 and SW1, why the frame is not tagged and that automatically goes into native VLAN?
    I guess trunk port setup is before native VLAN, and since the frame from PC to PC are both in VLAN 10, why is the frame sent untagged?
    Thanks for your explanation in advance.

    • @jzero1579

    Many Thanks for this series of videos, it is so fantastic
    I have a question please, Why does SW1 not use its mac address table to know which VLAN the packet belongs to? ( Please see the network I'm talking about at 17:10)
    I mean, if SW2 receives a packet in G0/2 belonging to PC connected to SW1 G0/1 interface, it should forward it through the trunk link, then when SW1 receives the packet check the MAC Destination address then forward it to the appropriate PC regardless of Vlan
    Thanks in advance

    Hey Jeremy @4:00 you explained traffic from pc2 will arrive with a tag of Vlan 10, so VLAN 20 does not need to be allowed on the trunk, however what about the return traffic from The pc on switch 2 on VLAN 10 back to pc2 on VLAN20?... that should have a TAG on VLAN 20 So switch 2 knows where to send the traffic and if VLAN20 is not allowed then the frame will be discarded. Please explain and thanks

      The traffic from the VLAN 10 PC will be tagged in VLAN 10 over the trunk, not VLAN 20. The PC is connected to a switch port in VLAN 10, so the switch assigns all of its traffic to VLAN 10 and therefore tags it in VLAN 10 over the trunk.
      It reaches the router as VLAN 10 traffic, and then the router sends it out as VLAN 20 traffic to the destination PC.

    31:36: Hello Jeremy, I confuse, you said that the router is tagging the frames which sent out of each sub-interface,
    Is the router is re-tagging the frames on their way out to the switch?
    Isn't it the switch responsibility?
    The switch suppose to get the frames from the router as it any other decice on the VLAN and tag it. That it's job, isnt it?

    • @JeremysITLab
      @JeremysITLab  2 роки тому

      The frames are sent to the router for routing. For example, let's say a host in VLAN 10 sends a message to a host in VLAN 30.
      The frames arrives on R1's g0/0.10 interface tagged in VLAN 10. R1 then checks the routing table and sees the destination is in the 192.168.1.128/26 subnet, connected to the g0/0.30 interface. So, it sends the packet out of g0/0.30, tagged in VLAN 30.

    This one was a little bit easier then the first video...I had problem with the LAB cause I like to recreate it and I was unable to ping the other VLANs. However the Pings did work internally in the VLANs..and when i did the simulation the ping look like it was actually flooding which I thought was weird. Yesterday I did try to solve this by trunking but I just confused myself what trunking was. This video help clarify that.

    Hi Jeremy...excellent series and course contents..@3:40...we see an example where PCs in VLAN 20 can send traffic to PCs in VLAN 10 via the router using inter-vlan routing. If VLAN segmentation is supposed to provide some increased level of security, how does this inter-vlan routing provide this security benefit?

    • @JeremysITLab
      @JeremysITLab  3 роки тому

      We can configure security policies on the router to control which devices can communicate with each other

    Hi Jeremy thanks for the content but I have one doubt at 16:15 u said frame coming from vlan 10 which is native vlan is tagged for vlan 30 but because vlan 10 is native then I think it shouldn't be tagged and because vlan 30 also native switch must forward the packet to vlan 30 however vlan 30 have separate subnet replay won't come but my point is switch should forward the packet...pls help with it

    At 5:33, why doesn't the sw2 forward to R1 first before it send to sw2? Thought only routers can do inter vlan routing?

    • @mahdou3608
      @mahdou3608 2 місяці тому +1

      its not inter-vlan in this case its from vlan 10 to vlan 10

    Hello Jeremy. I got a few questions
    At 13:12 when you were explaining when a PC wants to send to another PC in the same VLAN but different switches.
    ( PC-X -> SW2 (Tags VLAN 10) -> SW1 -> PC-Y )
    Got some questions:
    1) PC1 is forwarded to SW1 from SW2 without going through router?
    2) If so, does that mean PC-X is sent with destination mac address of PC-Y?
    Then is the router only used in this case through inter-vlan routing and access to the internet?
    Meaning if PC-X wants to send to PC-Z in Vlan 30, does that mean PC-X is sent with destination MAC of its default gateway, is this what happens?
    PC-X -> SW2 (Tags vlan 10) -> R1 (encapsulates dest mac of PC-Z) -> SW2 (Looks at L2 header and sees dest mac add) (removes vlan 10 tag and adds vlan 30 tag) -> SW1 (Looks at L2 dest mac + vlan tag 30) -> PC-Z in vlan 30
    Is that correct?
    Also does the switch decide which vlan tag it puts by looking at the destination mac address?
    Thank you Jeremy
    EDIT: I am so sorry, I just realized something, I was just confused. It's like routing. If PC wants to send to a PC in the same broadcast domain, the router is not used. If in another lan, the router is used for routing.
    Same case in VLANs, vlans are basically also different broadcast domains. So if a PC wants to send to another PC in the same VLAN, the PC will ask itself "Do we belong in the same VLAN?" If yes then it will be sent with dest mac of that PC, if not, dest mac of its default gateway, which then will be sent out with the appropriate vlan tag as explained in ROAS
