Release Information
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.
Description
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.
