DHCP Relay configuration diagram

Experiment topology diagram:

①R1 for DHCP server, configure 172.16.1.0/24 and 172.16.2.0/24 two address pools

②PC1 Get 172.16.1.0 network segment IP, gateway for 172.16.1.254

③PC2 Get 172.16.2.0 network segment IP, gateway for 172.16.2.254

1.R1, R2 Configure IP and open port.
