In case declaring DHCP server in CISCO routers, should define pool with network addresses.↓
Example
Router(config)#ip dhcp pool net1
Router(dhcp-config)#network 192.168.1.0 255.255.255.0
The router has predefined interfaces ip address and subnet mask.
Thus for each interface can only define dhcp service enable or disable? and dhcp options. and excluded-address
.
Why should we write Router(dhcp-config)#network 192.168.1.0 255.255.255.0
?
