  VLANs are used to divide a physical LAN into multiple broadcast domains to isolate services with the aim of improving the security and management of the network. Hosts within a VLAN can directly communicate only with other hosts in the same VLAN and must use a router to communicate with hosts in other VLANs. Put IP Address to every PC Like this:   PC0   PC1     Now go to Switch CLI mode and done those command:     Here are the Configuration command for two Switch:     Switch> Switch>en Switch# Switch#conf t Enter configuration commands, one per line. End with CNTL/Z. Switch(config)#vlan 15 Switch(config-vlan)#name SRK Switch(config-vlan)# Switch(config-vlan)#ex Switch(config)# Switch(config)#vlan 16 Switch(config-vlan)#name SK Switch(config-vlan)#ex Switch(config)# Switch(config)#int range f0/1-2 Switch(config-if-range)#switchport mode access Switch(config-if-range)...

    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....
