Configure dhcp servers for networks 192.168.3.0/24 and 192.168.4.0/24, even though they are not directly connected to the Core.Configure the two interfaces connecting to Site1 and Site2 routers with IP addresses 192.68.1.1/30 and 192.168.2.1/30 respectively.The following tasks will be performed on the Core router: Let’s look at the network topology below before we proceed. The task is simple with very minimal configuration commands but must be done carefully, considering that Site1 and Site2 LAN hosts are not directly connected to the core router. But wait a minute, why can’t we just configure Site1 and Site2 routers as dhcp servers to the hosts behind them instead of provisioning them as Cisco dhcp relay agents? Well, you can, but that will mean having multiple dhcp servers as your network grows and that could make the job of IP management a complex task. Their job is to help take dhcp requests from hosts to the dhcp server and deliver IP addresses from the dhcp server to hosts. Site1 and Site2 routers will be configured as Cisco dhcp relay agents. For this lab, my core router is going to be configured to serve as a dhcp server to the two local area networks attached to site1 and site2 routers.
