To configure an interface as a trusted source of the Dynamic Host Configuration Protocol (DHCP) relay
agent information option, use the dhcp relay information trusted command in interface configuration
mode. To restore the interface to the default behavior, use the no form of the command.
Command Syntax
dhcp relay information trusted
no dhcp relay information trusted
Default
All interfaces on the router are considered untrusted.
Command Mode
Interface configuration
Usage
By default, if the gateway address is set to all zeros in the DHCP packet and the relay information
option is already present in the packet, the DHCP relay agent will discard the packet. If the dhcp relay
information trusted command is configured globally, the DHCP relay agent will not discard the packet
even if the gateway address is set to all zeros. Instead, the received DHCPDISCOVER or
DHCPREQUEST messages will be forwarded to the addresses configured by the dhcp-server
command as in normal DHCP relay operation.
