Router configuration practice teaches you how to communicate with each other on three hosts in Linux in two network segments

Hello, everyone. I am your holy Grail.

It's time for you to explain to everyone in the Holy Grail.

Today, I'm taking you on a big project, you believe it or not.

If you accidentally open this document, I hope you'll be able to read this post for two days, so please respect my labor and pretend to finish it. Crossing, thank you.

First, you are welcome to Watch the operation steps

We're officially starting.

Topic:

Routing Configuration Practices:

The network information of the server needs to be configured according to the topology

the Linux Server needs to be accessible to Linux servers. To access

transforms a Linux server into a single router

To implement the test methods that linux01 and linux03 can access each other, the traceroute proves that the hosts are interoperable

Description: Implement the Route Configuration project practice According to the route command above

Let's look at this chart first get the following information

A Machine :10.0.0.10/2

Gateway:10.0.0.254

machine b :10.0.0.11/24

Gateway:10.0.0.254

10.0.1.11/24

Gateway:10.0.1.254

C Machine :10.0.1.11/24

Gateway:10.0.1.254

do the problem. The first idea is

Process the source host first We need a little white machine . to avoid conflicts such as Macs if you directly clone your current machine you will be in the Clone Computer Configuration network card Restart when the mac error specific errors you can try

do three of ABC three virtual machines connect clones here

Modify virtual network for VMS

separately for Network of ABC

make a xshell connection

Renamed

to test processing

a : Processing the source host

Before cloning in

Use the following command

Vim/etc/sysconfig/network-scripts/ifcfg-eth0

deleted in Mak Address and UUID these two lines

The effect after deletion

[Email protected] ~]#>/etc/udev/rules.d/70-persistent-net.rules

immediately after emptying the file to execute the above command It's right without an error.

this is a Network rule configuration file

[[email protected] ~]# echo ' >/etc/udev/rules.d/70-persistent-net.rules ' >>/etc/s ' >>/etc/rc.local

then write this command to   

This is to write the above command to boot from

[Email protected] ~]# shutdown-h now
Shutdown for cloning

The operation on the source host is here.

two theVmthe processing1now we're cloning .

Right-click the server you want to clone select Manage clones
