Packet Tracer. Destination host unreachabl
Доброго времени суток, уважаемые форумчяне. Прошу помощи с настройкой сети. Не получается.
During my network engineer career, one of the common errors I received while troubleshooting connectivity issues is Destination Host Unreachable.
This error was the cause of my Internet connectivity problems most times.
The same can be true for you too. When you troubleshoot your connectivity problems, the chances of getting this ping reply are very high.
If you learn how to resolve this error by yourself, you can fix most of your Internet connectivity problems yourself. In this tutorial, I will explain everything about this error.
By the first part, you will learn the meaning of this ping reply.
The second part of this article explains the reasons to get the ping reply Destination Host Unreachable.
You will learn how to fix the Destination Host Unreachable ping error in the last part.
What does Destination Host Unreachable Ping Reply Mean?
Before proceeding to the core of this tutorial, let me explain the meaning of this ping reply.
Now you understand the meaning of this ping reply. However, to learn more about this error, you should ask yourself two questions.
Let me answer the questions one by one. But before I explain the first question, you must learn how the ping operation works.
When you ping an address, this is how it works.
Can you tell me the potential sources for a Destination Host Unreachable reply from this ping workflow algorithm?
You can get this reply from two possible sources.
How do you know whether the reply comes from your default gateway or remote gateway?
If you see the following format, check the IP address. Most of the time, X.X.X.X must be a remote gateway address. Which shows the error message you received is from the remote gateway.
If you don’t see an IP address in the error reply, your default gateway sends it.
Both error formats have different reasons. I will explain the reasons to get either format in the next part.
Reasons to Get the ICMP Error Destination Host Unreachable
Any one of the reasons listed below can get you to the ICMP Echo message Destination Host Unreachable.
One of the frequent questions I received from our readers is whether this error is related to the Operating System like Windows error and Linux error?
Analyzing the ICMP Echo Destination Host Unreachable
Let me explain why I received this ICMP Echo by analyzing a live example.
Here I send ping packets to the global DNS address 4.2.2.2 to troubleshoot the connectivity problem. The screenshot below shows the reply I received.
Which format is this? It is the second format of the Destination Host Unreachable error. Let me explain how to resolve this error.
How to Fix Ping Error Destination Host Unreachable?
If you do not want to go into the complexity of this ICMP Echo, you can follow the instructions below to resolve the Destination Host Unreachable Ping error message.
Aggressive firewall settings can cause the destination host unreachable error.
To check whether the firewall is the reason for this issue, disable it on your computer.
Try to access the Internet after disabling the firewall.
Sometimes devices fell into the IP version conflicts. Different operating systems have different IP version priorities.
Windows 10 prefer IPv6 to IPv4. The same is true for the major Linux variants like Ubuntu, Fedora, Debian, etc.
However, sometimes devices fail to work properly with IPv6.
Rarely it results in ICMP error messages. We can check it by disabling the IPv6 on your device.
Let us check how to disable the IP Version 6 on a Windows 10 computer and test the issue.
Once you reboot your computer, check for the connection.

Destination host unreachable
Всем привет
Делаю простенькое задание по маршрутизации сети и выскакивает ошибка «Destination host unreachable», когда пытаюсь пингануть 104.0.0.1 или 105.0.0.1 с 101.0.0.1
Подскажите, в чем может быть проблема
Дополню:
Это же задание нужно было реализовать при помощи виртуальных машин и та же проблема при статической маршрутизации выскакивает и на них
На Router0 команда route print выводит все маршруты, кроме пути в сеть 104.0.0.0 и 105.0.0.0
Не знаю, что я мог сделать не так, несколько раз перепроверил внесенные данные и вроде все правильно ввел
Еще вопрос: при построении данной сети при помощи виртуальных машин, нужно ли каким-то образом реализовать коммутатор (switch) или без него должно работать?

How to Fix Destination Host Unreachable Error?
Do you know the most difficult part of the job of a network engineer? You are responsible for every issue related to networking in your company. Even though everything works fine, someone will come up with a complaint, and it is on our head to fix it.
While I was working as a network engineer trainee, I received a call from the development section. The manager on Duty in the development section was angry and said that the network was not working.
When I asked him about the issue, he said the Internet is just fine, but one of his teammates received an error while pinging to a device in his subnet.
His teammate received the Destination Host Unreachable reply while he tried to ping to another computer in his section.
The manager on Duty demanded an explanation for the Destination Host Unreachable. I explained to him the reasons to receive Destination Host Unreachable error messages with examples. If you have not seen this error message before, have a look at the screenshot attached below.
What Is The Reason to Receive Destination Host Unreachable Error Message?
If you want a one-sentence answer, look at the statement in the table.
Either there is no device with the IP Address you typed or your computer has a corrupted ARP table.
Let me explain with the example I showed above. When I sent Ping packets to the IP address 192.168.225.45 from my computer, it looked at the ARP table stored in my PC to fetch the MAC address associated with the destination IP Address.
You know the basic rule of network communication. You cannot send packets to an IP Address before finding the MAC address (Physical Address) of the destination device.
ARP table shows the MAC address of the devices assigned with the specific IP Address.
If you do not know this concept, there are tons of tutorials available about Address Resolution Protocol (ARP) on the Internet.
My computer could not find the ARP Address mapped to the IP Address 192.168.225.45 in the ARP table.
So it displayed Reply from 192.168.225.47: Destination host unreachable as the response.
How to Fix Destination Host Unreachable?
If you do not know how to fix the reply from the x.x.x.x destination host unreachable message, follow the instructions provided below.
The first step to troubleshoot the Reply from 192.168.225.47: Destination host unreachable error is by deleting all entries in the ARP table on your computer.
If the problem persists, you should run a traceroute to pinpoint the problem location.
Why do I receive the ping reply Destination Host Unreachable? The traceroute result shows there is no such destination device.
In my experience, some users said faulty Firewall settings caused the Destination Host Unreachable error. So, I suggest you turn off the firewall on your laptop and check for the issue.
If the destination device is in your reach, make sure the device is on. Make sure the network connection is fine.
You may unplug and replug the network cable to verify the connection status.
How to Check if Destination a Host Unreachable Error is Resolved?
It is very simple. You need to ping the same IP Address.
If the error is at the side of the IP Address, you should try to ping a different IP Address or domain name.
For example, check the command below to test whether the Destination a Host Unreachable Error fixed or not.
