MAC Blinding in DHCP-Server on GNS3

-

   

If we want to make a FTP-server in network 172 and network 192. We have to give same IP address in FTP-Server. So we have to make sure that every time that FTP-Server get same IP address so that user can access.


In R1 we gone create DHCP-server for two different network. Let’s starts

R1 Configuration



R1#conf

R1(config)#hostname DHCP-Server

DHCP-Server(config)#int f0/0

DHCP-Server(config-if)#no sh

DHCP-Server(config-if)#ip add 172.16.32.1 255.255.254.0

DHCP-Server(config-if)#ex

DHCP-Server(config)#int f0/1

DHCP-Server(config-if)#no sh

DHCP-Server(config-if)#

DHCP-Server(config-if)#ip add 192.168.10.1 255.255.255.0

DHCP-Server(config-if)#ex

Create two different POOL for 192.168.10.0 and 172.16.32.0 network

For network 192.168.10.0



For network 172.16.32.0



Now we are done with our configuration …now just put command ip dhcp in all pc for automatic IP address.

 

PC 1



PC2



PC3



PC4


PC5



PC6



Now we can see in PC5 & PC6 IP address is assign. But we will blind IP address 172.16.32.50 in PC5 and in PC6 we will blind 192.168.10.100

In R1à

For PC5


 

For PC6



 

We have done our configuration. Let’s see result

PC5

 


In figure see the IP Address before and after. New IP are assign

PC6
