group (DHCP Spoofing Prevention)

Syntax

Hierarchy Level

Description

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.

Configure DHCP snooping by including the appropriate interfaces under the group statement.
