For the past 30 mins, I've just read 5 articles, 3 other videos and only this vid helped me understand the true process of Tracert today. I never comment on KZfaq. Thanks a lot!

Brilliant explanation. I assumed TTL was an actual unit of time, such as a minute or second. When I realized it was just an increment/decrement operation, it made complete sense. Thank you.

u are the god of traceroute, i am CCNP and i never understood the concept behind tracert well until i first met your vid and in just 6 mins i am good and makes perfect fkin sense, cisco implementation of traceroute does not use true ICMP with TTL set to 1, it uses TTL = 1 with destination UDP port= 33434 mechanism to get the feedback from routers & therefore get the ip

So the number of hops depends on the latency of a router or an ap?

@ICDDD 4 жыл бұрын

And what happens when I lead the traffic from the target server to another server? Is this hop included into the traceroute?

@SuperAnxion 7 жыл бұрын

@kicsiqki 6 жыл бұрын

Neat explanation. My question is what happens when I run a traceroute, I get to the target address in 9 hops. So I have ten addresses on my scree, address 1 is the first gateway between my modem/router and the target, address 10 is the target. Address 9 has 100% packet loss even when running a traceroute every 3 seconds for 10 minutes straight, but the target address still has 0% packet loss and a normal ping. If address 9 is down, how can the packets even reach the target? How can I identify address 9? All I get is "No response from host" or "Request timed out", no host name or address is given so I cant even tell what gateway needs to be looked at.

@freebk161 5 жыл бұрын

100% packet loss; so you are probably getting * instead of a numeric value. This means you are not waiting long enough to fetch the Router information. So Increase the Wait time using the option, -w and number of queries by the option -q .

@mperu99 5 жыл бұрын

can you explain a bit more detail about when you see the * * * message , like you try to ping something that yo know should be there, but not able to ping now, so you use tracert and your first 5 hops you get a response, then * * * is that mean that switch is the issue?

what layers of the OSI model are hit during a traceroute? can all 7 layers be hit?

@SripsAKACypher 5 жыл бұрын

Traceroute uses ICMP requests which operate in Layer 3 (Network layer). So only the Network layer and the layers below it, viz., Datalink layer & Physical layer, are covered.

@adventureswithdavedave 6 жыл бұрын

could it be that different request go through different network segments outers based on things like load balancing and network conditions?

@DKolha 7 жыл бұрын

Why doesn't tracert show the ip of the network devices in the way? like, if you ping a host in the local network, even if there is a router, and than another router or an acess point in the way, it show it directly, 1 hop, as if it was a direct conection....

@CharlesHayden 7 жыл бұрын

If you only show 1 hop it should be because whatever device you are tracing to is the next "layer 3" device on that path. The TTL message will be reported back from layer 3 devices such as routers, layer 3 switches and firewalls ect. There could also be instances where your traffic is being tunneled through layer 3 devices where those intermediate layer devices appear to be transparent. Geoffrey also mentioned in the video that traceroute response messages could be blocked by network policies or not configured on neighboring devices. Hope that helps.

@DKolha 7 жыл бұрын

It helped a lot! ...So i guess it is because this access point and the router only work in layer 2 from PC till the printer as example.... the router is layer 3, but only when it routs outside, through the gateway....

@CharlesHayden 7 жыл бұрын

Yes, your devices will send unicast traffic to its gateway (the router) when you perform the traceroute. Other non-layer3 devices on the segment do not participate in this function.

So, when I send a request to google.com it goes through routers. Are they the ordinary routers of people at home or only organizations or service providers?
