Release Information
Statement introduced in Junos OS Release 9.4 (MX Series routers only).
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 to the MAC address of the client. These filters help prevent DHCP spoofing.
Configure DHCP snooping by including the appropriate interfaces in the DHCP relay configuration.
The statements are explained separately.
