[ no ] set dhcp relay

set dhcp relay { dhcpServerAddress [ proxy ] | agent [ circuit-ID-only |
remote-ID-only ] |inhibit-access-route-creation | discard-access-routes
{ all | interfaceType interfaceSpecifier | | unknown } }
no set dhcp relay { dhcpServerAddress | agent | inhibit-access-route-creation }
Command introduced before JunosE Release 7.1.0.
Command used without any keywords introduced in JunosE Release 8.2.0.
unknown keyword added in JunosE Release 9.2.0.
When used without any optional keywords, creates and enables DHCP relay in the current
virtual router independent of any DHCP servers.
When used with optional keywords, adds a new DHCP/BOOTP server and specifies that
the E Series router is either a DHCP relay or DHCP relay proxy between the DHCP client
and DHCP server. Optionally, configures the DHCP relay agent, including specifying the
DHCP relay agent information (option 82) that is included in all packets forwarded to
the DHCP server.
If you issue the set dhcp relay command when a local server has been configured, the
local server is deactivated.
The no version used without other keywords deletes the DHCP relay agent and its
configuration from the virtual route. The no version used with optional keywords removes
the specified server or disables the specified relay agent configuration.
NOTE: The set dhcp relay agent command, when used to configure option
82 suboptions, is a legacy command, which JunosE Software continues to
support to provide backward-compatibility for existing scripts. We recommend
that you use the dhcp relay agent sub-option command for new option 82
suboption configurations.
dhcpServerAddress—IP address of the DHCP server
proxy—Specifies that the router is a DHCP relay proxy between the DHCP client and
DHCP server; if omitted, the router functions as a DHCP server
agent—Adds the agent information suboptions (circuit-ID and remote-ID) to every
packet the router relays from a DHCP client to a DHCP server
