DHCP
DHCP
(Dynamic Host Configuration Protocol) is use to Provide Automatic ip address in
our Clients
{The exchange
of getting the ip address from the dhcp server is four step process}
To Configure Router as DHCP Server
Ø DHCP_Server(config)#interface f0/0
Ø DHCP_Server(config-if)#ip address 192.168.2.1
255.255.255.0
Ø DHCP_Server(config-if)#no shut
Ø DHCP_Server(config-if)#exit
Ø DHCP_Server(config)# ip dhcp pool DHCP_SERVER (DHCP_Server:- Pool Name}
Ø DHCP_Server(dhcp-config)#network 192.168.2.0
255.255.255.0
Ø DHCP_Server(dhcp-config)#default-router 192.168.2.1 (router int f0/0 ip address)
Ø DHCP_Server(dhcp-config)#dns-server 192.168.2.1
Ø DHCP_Server(dhcp-config)#exit
{To Reserve Some Address that we
will statically assigned}
Ø DHCP_Server(config)#ip dhcp excluded-address
192.168.2.10 {one ip address}
Or
Ø DHCP_Server(config)#ip dhcp excluded-address
192.168.2.10 192.168.2.20 {Range of ip
addresses}
{To Configure Router to Permit DHCP
{Broadcast} Request}
Ø Router1(config-if)#interface fastEthernet 0/0
Ø Router1(config-if)#ip helper-address 192.168.2.1 {this will allow Router to Pass
the DHCP Request from Client to DHCP Server}
