interface (DHCP Spoofing Prevention)


Hierarchy Level


Configure Dynamic Host Configuration Protocol (DHCP) snooping on the router. When acting as a snooping agent, the MX Series router typically is located between the client and the DHCP relay agent. It creates filters by “snooping” DHCP messages and binding DHCP-issued IP addresses with the MAC address of the client. These filters help prevent DHCP spoofing.

DHCP snooping is configured by including the appropriate interfaces.
