Group-Specific DHCP Relay Options

You can include the following statements at both the [edit forwarding-options dhcp-relay group group-name] hierarchy level to set group-specific DHCP relay agent configuration options, and at the [edit forwarding-options dhcp-relay] hierarchy level to set global DHCP relay agent configuration options:

• active-server-group—Configure an active server group to apply a common DHCP relay agent configuration to a named group of DHCP server addresses. For information, see Configuring Active Server Groups.
• authentication—Configure the parameters the router sends to the external AAA server.
• dynamic-profile—Specify the dynamic profile that is attached to a group of interfaces.
• interface—Specify one or more interfaces, or a range of interfaces, that are within the specified group.
• overrides—Override the default configuration settings for the extended DHCP relay agent. For information, see Overriding the Default DHCP Relay Configuration.
• relay-option-60—Use the DHCP vendor class identifier option (option 60) in DHCP client packets to select a DHCP server to which to forward packets. For more information, see Using Option 60 Information to Forward Client Traffic to Specific DHCP Servers.
• relay-option-82—Enable or disable the insertion of option 82 information in packets destined for a DHCP server. For information, see Enabling and Disabling Insertion of Option 82 Information.

The statements configured at the [edit forwarding-options dhcp-relay group group-name] hierarchy level apply only to the named group of interfaces, and override any global DHCP relay agent settings configured with the same statements at the [edit forwarding-options dhcp-relay] hierarchy level.
