@@user-ul3ms1og2f Yea that is one of my biggest issues with studying for CCNA is the flavors of vlan/trunking and remembering all of the topics and what goes to what. Like the information for Vlans, Etherchannel, Trunking, VTP/DTP then you have STP and its flavors and all of their similarities and differences.

@@bryanlemley9787 SW2 Fa1/0 and Fa2/0 are DPs because between SW2 and SW1, SW2 has a lower BridgeID. If you look at the MAC address on SW2 014A.3821 is lower than SW1 014A.38F1.

Jeremy, my brother and I started your CCNA program on Monday of this week. My brother and I are on Day 4 today. So far, we really enjoy your layout and information. You do a very good job explaining the information in direct and understandable fashion! If you don't mind me asking, how many "Days" do you anticipate you're going to post for the complete CCNA 200-301 course? Due to financial hardship, my brother and I have not downloaded Boson yet. Is it possible to simply go thru your course and pass the CCNA or would you recommend purchasing the Boson practice exams and Boson practice labs in addition to your course? We've been mainly using the Packet Tracer, using Anki, and watching/studying your videos as of right now.

Thanks for the comment, I'm glad you and your brother are liking the series :) I guess it will be up to 50 days in total, there's still a lot to cover. You don't NEED the Boson products to pass, but they are definitely helpful. If you're going to get just one, get the practice exams after you have studied all the exam topics, to help you prepare before taking the real thing. It's $99, but it could save you from having to retake the exam if you fail, which is much more expensive.

Same question for me. As for the remaining ports between SW2 and SW4, the designated port should be SW2.G0/0, whereas SW4’s G0/2 should be the ND port, because SW2 has lower MAC Address.
@kavianrowghani5085

@@kavissenmurday7029 SW2's G0/0, G0/1, and G0/2 all have a root cost of 8 (in the case of SW2'S G0/1 and G0/2: 4 from SW1's G0/1 and 4 from themselves. In the case of SW2's G0/0: 4 from SW4's G0/0 and 4 from itself.) Since all SW2's interfaces have the same root cost, the next tiebreak is to calculate the root cost from the lowest neighbor bridge id. Remember lowest bridge ID (BID) is a concatination of bridge priority plus MAC address. We can see that SW1 has the lowest neighbor BID. But SW2's G0/1 and G0/2 are tied here again. So, the next tiebreak is to calculate the lowest neighbor port ID. between SW2's G0/1 and G0/2, G0/2 has the lowest neighbor port ID: SW1's G0/0. Therefore, SW2's G0/2 is chosen as the root port.

So when determining the Root Port you only consider the root cost of each specific interface but when determining the root cost of individual collision domains you add the root cost for the entire switch?
@JeremysITLab
@JeremysITLab 3 года назад
That's correct. The switch wants to select the best interface to be the root port, so it compares the root cost of each interface. When deciding which side of the connection will be designated in a collision domain, the switches compare their root costs (=their cost via their root port)

the opposite side of the root port is always designated right?
@JeremysITLab
@JeremysITLab 3 года назад
Correct! The root port's role is to provide a path to the root bridge, so the opposite side must be designated (forwarding). If it's blocking it can't provide the path to the root.

Hi all, minute 34:10, why is not SW2 G0/0 the designated port? As far as I understand the root path cost from that interface is 8 (4+4) while the root path cost from SW4 G0/1 is 12 (4+4+4). Can anyone clarify that? Thanks

Hello Jeremy. I’ve said in other videos and I’ll say it again, thank you for the great videos! I have a question on this one on the quiz section that’s got me stumped. At times stamp 34:09 you say Switch 1s G0/2 is DP and SW2s G0/1 is non. I’m not making the connection. Wouldn’t the root cost on Sw 2 be 8 while the cost on SW 1 be 12, therefore making the roles be reversed on these ports? This is my first attempt on STP so I’m sure it probably something I’m missing, but…. Thanks in advance! Adding this edit after my post above…. Same on SW4 G0/1 and SW2 G0/0. I came up with reversed roles on the ports. My thinking is this: from sw4 you leave port G0/1 cost of 4. Leave switch 2 another cost of 4. Finally leave sw 3 another cost of 4 to get to root, which is a total cost of 12. Then from sw 2 you leave port G0/0 for a cost of 4. Out sw 4 for another cost of 4 to root for a total cost of 8.

@JeremysITLab Год назад
To select the Designated/Non-Designated ports, you compare the root cost of the switches, not the root cost of the ports you are deciding the roles of. Notice I stated 'Interface on switch with lowest root cost' becomes Designated, not 'interface with lowest root cost' becomes designated. SW1's root cost is 4, SW2's root cost is 8, and SW4's root cost is 4. SW2 has a higher root cost than the others, so its ports become Non-Designated.

I have been following your series and found very informative you are doing great. My question is in Quiz 5 SW4 interface G0/1 should be non designated port instead of SW2 interface G0/0 because both costs are same and SW2 bridge ID is lower, please explain.
@JeremysITLab
@JeremysITLab 4 года назад
SW4 has a root cost of 4 (via its G0/0 interface) SW2 has a root cost of 8 (via its G0/2 interface + SW1's G0/1 interface) SW4 has the lower root cost, so its interface becomes designated. Look at 32:00 in the video, I said the 'interface on the switch with the lowest root cost' will be designated, so that's why SW4's interface becomes designated. Let me know if you have any more questions :)

Man, what's crazy is I've taken many CCNA boot camps without the intent of testing. I'm in the Air Force and get free training since I'm in a enterprise IT networking position. I don't know if it's because I never put as much effort in or if past courses simply were ineffective, but I remember struggling to grasp the port role process. I had zero issues getting the correct answers on any of your quizzes after this lecture. Well done and thank you.

I read OGC I & II cover to cover, and I have to say watching these videos is more efficient and effective, while also being way less strenuous. Same material and concepts, but somehow Jeremy presents things in a way that is far more comprehensible to novices. I did learn a lot from OGC, but boy did I pay a price. At times I would get confused and bewildered, resulting in the whipping and gnashing of teeth; brimstone emanating from my nostrils. Never happens with Jeremy's labs or lessons. I Just sit back, relax, and learn.

now i understand it a little, we need to plot the flow of root cost first from the root bridge. before we determine who has the interface with the least root cost per switch.
