DHCP configuration on Mountain Sky Router

Although each school has its own DHCP server, the Cisco Router may be configured as a DHCP server but the overall network congestion and delays will be higher than if the addresses are obtained via a DHCP server.

To configure the router as a DHCP server the following commands have to be implemented:

MtnSky(config)# no ip dhcp conflict logging
(to disable conflicts about DHCP)
MtnSky(config-dhcp)#ip dhcp pool student_network

MtnSky(config-dhcp)#network 192.168.4.0 255.255.252.0

MtnSky(config-dhcp)#dns-server 150.150.95.3

MtnSky(config-dhcp)#default-router 192.168.4.1

MtnSky(config-dhcp)#lease 3

MtnSky(config-dhcp)#exit

(and the Ethernet interface must be configured)

MtnSky(config)#interface ethernet 2.1

MtnSky(config-if)#ip address 192.168.4.1 255.255.252.0

MtnSky(config-if)#no shutdown

An individual configuration based on each computer NIC MAC address may be implemented but that would need a high amount of NVRAM to save configuration, so the configuration presented would be better.
