Architectural devices:

One router, one layer 3 switch, one layer 2 switch, two servers, one providing DHCP+DNS service, one providing WEB web service, and two clients. Used to get addresses and tests.

The server that provides DHCP+DNS is replaced by CentOS 7.

The WEB web service is replaced by windows server.

One win 10 on the client. A win 7.

Project requirements:

1) sw2 is a layer 2 switch, and three vlan,f1/1-3 of vlan10,vlan20,vlan100 are access links.

F1ap0 is the trunk link.

2) sw1 is a layer 3 switch, which provides gateways for three vlan, vlan10:192.168.10.1/24, vlan20:192.168.20.1/24, vlan100:192.168.100.1/24 and f1amp 1pur12.0.0.1and24.

3) the local area network internal Linux server builds the dhcp service function to provide addresses and address ranges for vlan10,vlan20 and vlan100

Vlan10:192.168.10.100~192.168.10.200 subnet mask: 255.255.255.0 gateway 192.168.10.1Univer 24

Vlan20:192.168.20.100~192.168.20.200 subnet mask: 255.255.255.0 gateway 192.168.20.1 Universe 24

Vlan100:192.168.100.100~192.168.100.200 subnet mask: 255.255.255.0 gateway 192.168.100.1 Universe 24

The address of the dns server is: 192.168.100.100Universe 24

In which the PC1 host always gets the 192.168.10.18 Universe 24 address.

4) build DNS service function in local area network Linux server to analyze www.kgc.com and www.yun.com

The resolution address is 14.0.0.14/24web server, and the pan-domain name resolution function is provided. The resolution address is 8.8.8.8

5) outside the local area network, there is a WEB server built by server2016, and the virtual machine host is established to provide two websites, namely www.kgc.com and www.yun.com, to customize the differential display of home page content.

6) realize the final interconnection of the whole network and improve the function access.

DHCP + DNS + WEB Integrated Architecture Topology Diagram:

1. Install the DHCP service installation package and the DNS service installation package in CentOS 7

2. Set all the network cards to host-only mode, and turn off the function of automatically obtaining DHCP services.

Assign Vmnet1 to win 10, Vmnet2 to win 7, Vmnet3 to CentOS 7, and Vmnet8 to windows server.

3. Configure layer 2 switch sw2

Turn off the routing function

Create 3 vlan, namely vlan10, vlan20 and vlan100

Enter port f1max 1, assign it to vlan10, and set vlan mode to access

Enter port f1max 2, assign it to vlan20, and set vlan mode to access

Enter port f1max 3, assign it to vlan100, and set vlan mode to access

Enter interface f1max 0, set the vlan mode to Trunk, and specify the encapsulation protocol as 802.1q

4. Configure layer 3 switch sw1

Create 3 vlan, namely vlan10, vlan20 and vlan100

Enter interface f1max 0, set the vlan mode to Trunk, and specify the encapsulation protocol as 802.1q

Enter vlan10, configure IP address, and subnet mask, specify DHCP server port address, and open

Enter vlan20, configure IP address, and subnet mask, specify DHCP server port address, and open

Enter vlan100, configure IP address, and subnet mask, specify DHCP server port address, and open

Enter port f1max 1, convert layer 2 port to layer 3 port, configure IP address, subnet mask, set speed, and turn on weighted duplex mode

Set default rout

5. Configure router R2

Enter port f0max 0, configure IP address, subnet mask, and turn it on

Enter port f0max 1, configure IP address, subnet mask, and turn it on

Configure static rout

6. Configure DHCP service

Enter the network card directory and configure a static IP address

Restart the network information and view the network card information

Enter the dhcp configuration file for configuration

Set DNS resolution address

Add the network segment and subnet mask of the DHCP relay service, and assign the range. And Gateway

Set a fixed IP address to a client

Return to the win 10 client and use ipconfig / all to view the physical address

Configure win10 with a fixed IP address

Restart the DHCP service

Verify the DHCP service

7. Configure DNS service

Enter the main configuration file of the DNS service to configure

Go to the zone profile and configure it

Copy a copy of the configuration file in named.localhost to kgc.com.zone, and configure it under kgc.com.zone.

Copy a copy of the configuration file under kgc.com.zone to yun.com.zone

Turn off firewall and security features

Enable the named service

Verify DNS parsing

8. Configure WEB web pages

Enter windows server to configure IP address, subnet mask and gateway

Create two web pages in windows server

Add a web web service

Create two successful websites

Next, let's test the connectivity between the web page and the Internet.

Through the client pingCentOS7 server and windowsserver server

We have completed the above framework.
