ip bootp-use-intf-ip

Configures a Dynamic Host Configuration Protocol (DHCP) relay agent to set the source IP address of a DHCP-client packet with the IP address of the interface in which the DHCP-client packet is received.
Syntax
ip bootp-use-intf-ip
no ip bootp-use-intf-ip
Command Default

The DHCP relay agent sets the source IP address of a DHCP-client packet with the IP address of the outgoing interface to the DHCP server.

Modes

Global configuration mode

Usage Guidelines

You can configure ACLs on a DHCP server to permit or block access to the DHCP server from particular subnets or networks. You can then use this command on the DHCP relay agent to reveal the source subnet or network of a DHCP packet to the DHCP server, which enables the DHCP server to process or discard the DHCP traffic according to the configured ACLs.

The no form of the command restores the default behavior. The DHCP relay agent sets the source IP address of a DHCP-client packet with the IP address of the outgoing interface to the DHCP server.

Examples

The following example configures a FastIron DHCP relay agent so that it sets the source IP address of a DHCP-client packet with the IP address of the interface on which the DHCP-client packet is received. 

device(config)# ip bootp-use-intf-ip
