Syntax source-address-giaddr;
Hierarchy Level [edit forwarding-options helpers bootp],
[edit forwarding-options helpers bootp interface interface-name]
Release Information Statement introduced in Junos OS Release 10.1 for EX Series switches.
Description Configure the gateway IP address (giaddr) as the source IP address of the switch for
relayed DHCP packets when the switch is used as the DHCP relay agent.
When this statement is entered in the [edit forwarding-options helpers bootp] hierarchy,
the gateway IP address is configured as the source IP address of the switch for relayed
DHCP packets exiting all interfaces on the switch.
When this statement is entered in the [edit forwarding-options helpers bootp interface
interface-name] hierarchy, the gateway IP address is configured as the source IP address
of the switch for relayed DHCP packets exiting the specified interface of the switch.
In Junos OS Release 10.1 for EX Series switches and later releases, the IP address of the
interface that the DHCP packet exits on the switch acting as a DHCP relay agent is used
as the source IP address for relayed DHCP packets by default.
In Junos OS Releases 9.6 and 10.0 for EX Series switches, the gateway IP address of the
switch is always used as the source IP address for relayed DHCP packets when the switch
is used as the DHCP relay agent.
In Junos OS Releases 9.3 through 9.5 for EX Series switches, the IP address of the interface
that the DHCP packet exits on the switch acting as a DHCP relay agent is always used
as the source IP address for relayed DHCP packets.
