User devices can automatically obtain IP addresses after DHCP is configured. If a 
user connects a small router to the intranet and enable the DHCP server on the router, 
authorized intranet users may obtain IP addresses allocated by the small router and 
cannot access the Internet. To prevent this problem, configure DHCP snooping.
Department A is used in the example below.

Enable DHCP snooping on interfaces that connect to user devices.

After the preceding configuration is complete, user devices in department A can 
obtain IP addresses from only the authorized DHCP server, and will not use IP 
addresses allocated by the small router.
