Create «trusted» security zone and determine the inherence of the network interfaces being used to zones:
esr# configure
esr(config)# security zone trusted
esr(config-zone)# exit
Create address pool named «Simple» and add IP address range intended for server clients lease into this pool.
Specify parameters of the subnet that the pool belongs to, and the lease time for addresses:
esr# configure
esr(config)# ip dhcp-server pool Simple
esr(config-dhcp-server)# network 192.168.1.0/24
esr(config-dhcp-server)# address-range 192.168.1.100-192.168.1.125
esr(config-dhcp-server)# default-lease-time 1:00:00
Configure transfer of additional network parameters to clients:
